Simple requirements for each step of charcoal machine
Each production process of the charcoal machine has a direct relationship with the charcoal production effect. The charcoal process requires four steps: crushing, rod making, drying and carbonization. Each step requires different equipment and technical requirements. In order to produce high-quality charcoal, every step must be skillfully operated. So what are the requirements of each step of the charcoal machine?
1. In the process of crushing raw materials, the size of the crushed large materials should be kept between 10mm, and do not exceed this particle size, so as to affect the operation;
2. During the rod making process, the density of the rod body should be reasonably controlled, and the density value to be maintained should be a 1: 1 ratio;
3. For drying materials, the humidity of the materials should be controlled at the optimal dryness. Generally, the controlled moisture content is 6% ~ 12%;
4. During the carbonization process, the temperature of the carbonization should be controlled to the optimal carbonization temperature range. The carbonization temperature is generally required to be between 550-600 degrees, which is the optimal carbonization temperature range value.

How to prevent corrosion of finished charcoal made by charcoal machine
Recently, a customer friend from Shaanxi called us and said that he has a lot of fruit trees in his hometown. Every year, he cuts a lot of fruit branches and throws them away as garbage. It is a pity that messy throwing on the ground is also a hindrance, so I thought Find a device that can be used.
We also have customer response to the situation he responded to. This situation is most suitable for charcoal. The raw materials can be said to be free, so the profit margin is greatly improved. If there are many small branches, we recommend making charcoal. The equipment required for carbon is a pulverizer, rod making machine, dryer and carbonization furnace. If it is a large branch, it is recommended to use the original charcoal machine to directly carbonize, and the tree stem to directly carbonize the charcoal (fruit charcoal).
At present, the price of fruit charcoal on the market is still very ideal. Making good quality charcoal, using fruitwood or hard mixed wood, the carbon produced will have a higher calorific value than rice husk char.
The discarded branches can be solved by reasonable use, and the next problem comes again. Sometimes the charcoal produced cannot be sold in time and needs to be stored, but what should be paid attention to when storing? How to store it?
The charcoal machine completes the production process of charcoal after the raw materials are processed through the four processes of crushing, drying, rod making, and carbonization to produce charcoal. For some users, the charcoal produced is not directly sold and needs to be packaged and stored, and the storage time cannot be guaranteed.
Some charcoal is damaged and corroded when it is used. It cannot be used normally. This makes users question whether the charcoal produced by the charcoal machine is not effective, or what causes it. In fact, the key point is that the charcoal produced by the charcoal machine needs to be preservative treated.
The ingenious anti-corrosion treatment measures of the charcoal produced by the charcoal machine are natural drying. Natural air-drying requires that the finished charcoal machine is air-dried at the place where the test machine is used. This process is mainly aimed at the changes in the charcoal cell structure caused by changes in the external environment, so that it can be fully fixed to the greatest extent during the gradual change process, thereby avoiding the finished charcoal machine in Changes occurred during storage.

Production efficiency of continuous carbonizer
The finished products produced by the continuous carbonization machine all belong to the charcoal category. The raw materials are different, so the processed charcoal is also different. The main difference between them is the energy released by the charcoal. Charcoal produced from different raw materials releases different energy. Of course, this is also related to the production quality of the continuous carbonization machine.
The calorific value of charcoal and the carbonization temperature of the continuous carbonization machine, and the holding time of the continuous carbonization machine are directly related. Only a high-quality continuous carbonization machine can process high-quality charcoal. In the daily processing of continuous carbonization machines, the higher the carbonization temperature, the longer the holding time, and the greater the carbon content, the overall calorific value will also be higher, which also depends on the continuous carbonization machine Production of equipment.
Generally, the calorific value of charcoal processed by wood and corner waste from continuous carbonized is between 7000 kcal / KG, and the calorific value of charcoal processed by straw and rice husk from continuous carbonized is 6000 kcal / KG. Therefore, the calorific value of charcoal depends not only on the continuous carbonized equipment but also on the raw materials.

How is the continuous carbonization machine carbonized?
When the continuous carbonization machine is started, the furnace cover must be closed before ignition, and asbestos cloth must be added to prevent safety problems during production. There must be no fire or air leakage during production. In this case, the wooden stick can be ignited. Spontaneously ignited.
The general burning time of continuous carbonized equipment is about 8 hours, and the cooling time is also tightly required for about 12 hours, so the carbonization efficiency of continuous carbonized is still very high.
A continuous carbonization machine is a new type of environmentally friendly carbonization furnace. It needs to be placed on the horizontal ground during installation. The furnace cannot be tilted. The wooden rods need to be put into the iron frame one by one.
Due to the good sealing effect of the continuous carbonization machine and the recovery and purification of the carbonized flue gas into a flammable gas, the entire carbonization process can achieve no energy loss and no smoke emission, ensuring the environmentally friendly production of the continuous carbonization machine.

How to increase the charcoal output rate of charcoal machine equipment
For charcoal machine equipment, the charcoal output rate of charcoal machine equipment marks its production efficiency, that is, the higher the charcoal output rate, the higher the charcoal machine equipment production efficiency, so as to have better income Can make more customers like it. There are many ways to increase the charcoal output rate of the charcoal machine equipment, and there are many factors that affect the charcoal output rate of the charcoal machine equipment. These need to be paid more attention to production personnel.
Charcoal needs to undergo a high temperature and high pressure process during the carbonization process, so its production density is very large, about 3 times that of ordinary wood, much higher than ordinary charcoal, and the ash content is also very low Charcoal is one of the popular factors. If you want to improve the carbon yield, you can start from the source of the raw material. In the process of raw material crushing, you need to master the uniformity of the particles of the crushed material, improve the density of the charcoal rod, and then increase the carbon yield.

What are the important links of the charcoal machine production line?
The charcoal production line is manufactured by people in order to be able to produce more energy-saving and environmentally friendly resources, which can reduce the waste of resources in the society. These waste resources are processed into machine-made charcoal for processing, and the charcoal machine production line has many advantages. Users are investing in charcoal machine production lines, but for some users, the charcoal machine production line production mechanism charcoal is not comprehensive, do not know what important links in the charcoal machine production line production mechanism charcoal?
Drying and rod making in the charcoal machine production line:
After the raw materials are transported into the factory, the raw rods can be produced after screening and drying. The key step before forming the rods is drying. The moisture content of the drying must be reduced to 12% to 6% to make rods. Therefore, the selection of the dryer is very important, and the requirements are very high. Once the raw material with 35% water content is dried to 10%. Inexperienced beginners usually enter a wrong understanding, they think that the molding machine can not be molded.
After molding, the density of the raw material is small, the cracks in the rod, and the weight are all wrongly assumed that the molding machine is not good. They have forgotten the role of the dryer. Whether the moisture content of the original material has passed or not, there is a very important relationship between formation and failure. Drying is one, molding is two. Therefore, the drying effect determines the molding quality, which is very important.
The charcoal output rate of the charcoal machine production line is related to the temperature. The charcoal output rate of the charcoal machine production line is different due to different types of raw materials. The wood fiber content of the raw material has a positive effect on the production of charcoal. Dense materials can also produce dense and strong machined carbon. Although a lower carbonization temperature can obtain a higher carbon yield, but because of this mechanism, charcoal has low quality and corrosiveness, contains acid tar substances, and cannot be burned with a clean smokeless flame.
The solid carbon content of better commercial carbon should be higher than 80%, which requires us to control the final carbonization temperature above 500 ℃. However, as the carbonization temperature increases, the fragility of charcoal will also increase, and in actual production, when the final carbonization temperature is between 550 ℃-650 ℃, the fragility of the charcoal and solid carbon The content can reach a more ideal balance.

What is the use of charcoal machine production line in industry?
The machine-made charcoal produced by the charcoal machine production line is more and more popular in the market because of its low cost and longer burning time than traditional charcoal. Machine-made charcoal is not only in people's lives It still plays a very important role in the development of society. In addition, the machine-made charcoal produced by the charcoal machine production line has a great influence on industrial production.
1. Metallurgical industry
Previously, charcoal was used to smelt iron ore. The pig iron smelted with charcoal and coke has different structures and mechanical properties even if the chemical composition is the same. Pig iron smelted with charcoal generally has a fine-grained structure, compact castings, and no cracks. Pig iron produced with charcoal contains few impurities and is suitable for the production of high-quality steel.
In the production of non-ferrous metals, charcoal is often used as a surface flux. When the non-ferrous metal melts, the surface flux forms a protective layer on the surface of the molten metal to separate the metal from the gaseous medium, which can reduce the splash loss of the molten metal and reduce the melting. The saturation of the gas in the material. A large amount of charcoal is also used in the production of crystalline silicon. The charcoal used in the production of crystalline silicon should not contain green char and excessive ash.
2. Manufacture of carburizing agent
All steel products that require high hardness and wear resistance on the surface and good toughness in the center must be carburized. The carbon-containing mixture used to carburize steel products is called a carburizing agent. The carburizing effect of simple charcoal is poor. Therefore, charcoal is commonly used as raw material, and then a certain amount of contact agent is added to make a carburizing agent.
3. Carbon disulfide production
Charcoal is a better raw material for manufacturing carbon disulfide. The charcoal used to make carbon disulfide should be hard, large in volume, low in ash and moisture, and high in fixed carbon. It takes about 0.5 tons of charcoal to produce 1 ton of carbon disulfide.
4. Suppression of charcoal bricks
The transportation of crushed charcoal is very inconvenient, and the use is also limited. The method of pressing charcoal bricks can make small value charcoal into high-quality fuel. Charcoal brick has the advantages of low hygroscopicity and water absorption, large specific gravity and high calorific value, and has high mechanical strength during use. The calcined charcoal bricks are smokeless when burned and do not produce carbon dust. Charcoal bricks can be used in metallurgy, mobile gasifiers, etc.

Charcoal machine promotes the development of biomass energy
In recent years, the country has been encouraging the development of the charcoal machine biological resource industry, and the industrial development of biomass energy has been promoted. However, the development level of the industry has been slower than the use of wind and solar energy, and industrialization has not been well-formed. We Will question whether environmental protection will not bring the economy, and economic will not reach environmental protection. So how to effectively promote the problems of biomass energy and mobilize enthusiasm to effectively solve these problems?
The smaller output of the charcoal machine is 1 ton per day, so the characteristics of the small charcoal machine equipment equipped with the air dryer are particularly prominent. High thermal efficiency: the airflow drying adopts the material and gas co-current manipulation, and the temperature of the material and air can reach a fair state from the beginning to the end. The drying time is short, so a higher drying temperature can be used. The carbonization furnace carbonizes the quality and output of the finished carbon, so the application of the dryer in the charcoal machine equipment is very important.
At the same time, because of the dispersion and agitation action during drying, the negative vaporized surface is constantly updated, so the heat transfer process of drying is strong. The small charcoal machine is a raw material crushing and destroying machine, a dryer, a rod making machine and a carbonization furnace. Several links are complementary. The airflow dryer has: the airflow dryer has a high airflow speed, and the materials are well dispersed in the gas phase. The entire surface of the material can be used as an effective area for drying. Therefore, the drying area is greatly increased.
China is a largely agricultural country with rich biomass resources, wide variety, and wide distribution. This is the advantage of China's rapid development of biomass energy, but it is also a problem we have to solve. The biomass energy industry has always had insufficient raw materials and insufficient outlets for by-products. Although biomass resources are abundant, many raw materials have a small proportion, large body size, many types, and scattered distribution. It is difficult to collect, store, and transport resources such as straw. Labor costs continue to rise, if the national regulatory force is not enough, it will cause the raw material cost is too high or the raw material collection is insufficient, which can greatly affect the economic benefits of the enterprise.

Machine-made charcoal will inevitably replace the original charcoal
In today's society, people pay attention to their own health, and environmental factors are also one of the important reasons that affect people's health. The air pollution makes the smog more and more serious, people have to wear masks when going out. With the continuous improvement of people's awareness of environmental protection, equipment that damages the ecological environment is gradually being eliminated, and the development of charcoal machine equipment is bound to replace the original charcoal.
Because neither our country's economic or environmental development methods can develop retrogressively.
Let us introduce the advantages of machine-made charcoal compared with the original charcoal production method?
1. More environmentally friendly: The raw materials for the production of charcoal machines are diversified, and waste can be turned into treasure. The original method can only destroy the ecological environment by cutting down trees.
2. Good cleanability: machine-made charcoal has no probe, burning without sparks, and small ash content.
3. High energy: The calorific value of machine-made charcoal is about 1000-1500 kcal/kg higher than the charcoal caused by traditional methods.
4. Low water content: The charcoal produced by the charcoal machine undergoes a series of treatments and the originally manufactured charcoal has lower water content.
5. A particularly obvious advantage is that the shape rules, length, and size are relatively uniform.
The above analysis is that the replacement of the original charcoal with a charcoal machine is an inevitable reason for development. Now, whether it is rural or industrial, machine-made charcoal is used, which shows that the market for machine-made charcoal is very extensive.

Precautions for installing charcoal dryer
When you buy a wood dryer home, the technician's wood dryer company will return to your home and install it for free. The following are the precautions for installing the wood dryer:
Wood dryer
1. Foundation acceptance, mainly check the foundation concrete pouring quality and size position deviation. Its appearance requires that the foundation surface is clean, free of oil stains, dust, debris, no exposed steel bars, no crack angles, and no casting defects such as residual shell plates in the expected holes. The deviation of the size and position of the foundation should meet the following requirements: For the shape, size and position of the basic coordinates, the error of the vertical axis and the horizontal axis is less than 20 mm. The elevation error of different planes is less than 20 mm, only Xu and Negative are not allowed to be positive, the total length of slope error is less than 20 mm, whether the discharge end is allowed to be positive, the unevenness of the upper plane is less than 5m, and the total length is less than 10 mm.
2. Wood drying equipment inspection, packaging wood drying equipment, parts, components, standard parts, inventory and other random documents supplied by the anti-skid control device, sent to the wrong check for missing parts, deformation and damage, etc., and used for good records, so install Before that, purchase or prepare. When packaging transparent protective coatings and coatings of dust, grease, rust spots, etc., as well as handling, caused damage during transportation, the received dressing is deformed. The key fitting part is pre-detected and pre-arranged to avoid rework of the installation work and ensure the progress of the installation quality of the installation.
three. Prepare the installation process, including basic installation procedures, basic installation procedures, installation process methods, and safety technical requirements. Then set the bottom plate, determine the reasonable layout of the bottom plate, and pay attention to the bottom plate should be as close as possible to the anchor rod, placed at the center of gravity of the load, to prevent uneven load on the bottom plate. The number of base plates in each group shall not exceed 5 pieces. Thicker pads should be placed up and down, thinner pads should be placed in the middle, and stacked pads should be in good contact. When the adjustments cannot overlap completely, the contact area should be greater than 80%. The bottom plate and the foundation should have sufficient contact accuracy so that the foundation is tightly contacted, placed stably, and there is no hollow angle sloshing phenomenon, ensuring that the bottom plate is tilted up and down the same as the foundation in the longitudinal direction; it should be basically horizontal in the horizontal direction. The baseline marking adopts the optical theodolite, laser collimator or the wire drawing method with poor precision to horizontally level and align the roller base, and repeat the vertical alignment several times until the coordinate position, horizontal horizontal and vertical inclination angle meet the requirements.

Sawdust dryer main structure and characteristics
The main structure and characteristics of the dust collector of the wood chip dryer. The wood chip dryer is a mechanical device designed and manufactured for the drying of sawdust, small wood chips, wood veneers, and wood chips. The main principle is to apply the principle of thermal communication. There is plenty of contact in the barrel to complete the purpose of evaporating water, drying, and dehydration under the action of high temperature.
Feeding installation: Wet wood chips are fed into the wood chip dryer barrel. The built-in "rotary rake crushing" installation belt in the first drying stage breaks up and crushes the wet materials, and converts the wet materials into loose particles that are easy to dry Under the action of the board, it is fully contacted with hot air, dried countercurrently, and quickly evaporates most of the water. In order to remove the biological water in the wet material, the wood chips are transferred to the second drying stage of the wood chip dryer.
At this time, the material and the hot air stop counter-current drying, and the material is repeatedly lifted in the middle layer from time to time, which not only fully absorbs the heat distributed by the inner drum, but also absorbs the heat of the middle drum to reach a better dry state. The material moves to the other end of the middle layer and falls into the outer layer. The material travels in a multi-loop way in the outer drum, and the two-step and one-step backward travel mode make the material that reaches the dry effect quickly travel out of the drum.

Industry advantages of new charcoal machine
The longer the extinguishing time of charcoal, the more users can be trusted. When purchasing a charcoal machine, you want to consume high-quality charcoal. The performance of high-quality charcoal is the length of extinction time. When charcoal is extinguished for a long time, the amount will be reduced, and the cost can also be used sparingly. Therefore, as long as the charcoal that has been extinguished for a long time is more popular.
So what is the way to improve the extinction time of the charcoal consumed by the charcoal machine? Progress in the charcoal machine rod making machine using the forming pressure of the original parts, and then increase the density and strength of the rod. After the final carbonization temperature of the high carbonization furnace (or carbonization kiln), and slow down the heating and cooling rate, the produced carbon has high density and high hardness. Of course, the quality of the charcoal machine itself is also very important.
Good quality guarantees efficiency guarantees output and is capable of preventing unnecessary losses. Therefore, the purchase of charcoal machine should choose a professional manufacturer. With China's attention to the environmental protection industry, various environmental protection products and equipment are constantly being produced. The new charcoal machine is one of them. The charcoal produced by the new charcoal machine is widely used and has good development prospects and stable development space, It Is a good investment project for the majority of users.
The charcoal machine produces charcoal with a wide range of raw materials, low prices, inexhaustible and inexhaustible. Some raw materials do not even cost money, such as wood processing residues: sawdust, wood chips, bamboo chips, bark, board bark, etc. Firewood forest, forest logging residues: branches, tree roots, etc .; agricultural and forestry by-product wastes: chaff, walnut shells, chestnut shells and other fruit shells and cores.

Charcoal carbonization process
Although the charring stage is not the most expensive stage in the entire charcoal production process, it is decisive. If this work cannot be carried out effectively, the entire production process will be in a dangerous state, because with the consumption of bar and the increase in cost, the low output of the carbonization stage will inevitably lead to inefficiency of the entire production chain.
The core of the competition between carbon plants that are normally produced in the same area is carbonization technology. The same amount of salary rods are taken to different carbon plants for carbonization, and the quality and quantity of the final finished carbon are different because of the difference in carbonization technology level. Scientific and reasonable kiln body design, a good kiln burning method is the key to producing more charcoal. This directly affects the level of profitability of a carbon plant.
Charcoal semi-finished products-the main components of the fuel rod include cellulose, wood fiber and water. Among them, cellulose and wood fiber and some other components are closely combined, which is why the mechanical strength of the salary rod is. Water is absorbed in the cellulose/wood fiber structure in the form of water molecules. The water content of the baton is generally below 9%.
This water will be dissipated in the form of water vapor before the effective carbonization process begins. The heat comes from the burning of a small number of fuel rods in the kiln. This is the so-called drying stage. Since the raw materials undergo strict drying treatment before being formed into salary rods, the drying stage in the carbonization process takes less time and requires less heat.
When the moisture content of the salary rod is close to zero, we need to continue to increase the temperature in the kiln. The heat required still comes from the burning of some of the rods in the kiln. When the temperature rises to 280 ° C, the sticks will spontaneously decompose, producing charcoal, methanol, acetic acid, and more complex chemicals. These chemicals often appear in the form of tar and non-condensable gases containing mainly hydrogen, carbon monoxide, and carbon dioxide. Because the air is allowed to enter the kiln, there is also a part of nitrogen from the air in the gas.
Only when the carbonized residue can be called charcoal, the carbonization and spontaneous decomposition will end. Unless more heat can be provided, the process will be terminated. At this time, the temperature reaches its maximum value of 400 ° C. However, this charcoal still contains an estimated amount of tar residues and native wood ash. The ash content of charcoal is about 3%-5%. Asphalt residue content is about 30%.
The rest is the so-called solid carbon, about 65%-70%. Further heating can increase the solid carbon content by removing and decomposing more tar. When the temperature reaches 500 ° C, the typical solid carbon content of 80% and volatile content of about 10% can be obtained. The charcoal extraction rate at this temperature is about 2.6: 1. The charcoal extraction rate will decrease with the increase of the final carbonization temperature.

Charcoal burning kiln technology
It should be pointed out that the carbon yield shows a certain difference due to the different types of raw materials. In addition, the structure of the kiln and the method of burning the kiln directly affect the carbon yield, so the numbers in the table are only used as parameters for your reference.
Although a lower carbonization temperature can obtain a higher carbon yield, this charcoal has low quality and corrosiveness and contains acid tar substances, so it cannot be burned with a clean smokeless flame. The solid carbon content of high-quality commercial carbon should be higher than 80%, which requires us to control the final carbonization temperature above 500 ℃.
The wood fiber content of the raw material has a positive effect on the production of charcoal. Charcoal production welcomes mature materials with a strong structure. Dense wood can generally produce dense and strong charcoal. However, as the carbonization temperature increases, the fragility of charcoal will also increase. In actual production, it was found that when the final carbonization temperature is between 550 ℃ and -650 ℃, the fragility of charcoal and the solid carbon content Time can achieve a more ideal balance.
The key to the burning kiln is to control the kiln temperature. Through the adjustment of the air inlet, the purpose of controlling the temperature of the kiln can be achieved. The stable heating and cooling process is the guarantee for burning high-density charcoal. Taking the climatic conditions of Jilin in spring as an example, the entire process from ignition to charcoal discharge takes about 9 days, so that charcoal with a more ideal density can be obtained.
For the southern carbon plant, the cycle is longer. The high-temperature carbon refining stage after the end of the spontaneous decomposition stage determines the solid carbon content of the charcoal. If you want to burn good charcoal, you must work hard to control the kiln temperature and high-temperature charcoal. In addition, the kiln body must be kept sealed at all times, and no air leakage is required, which requires us to be very careful when building the kiln, especially in the drying stage of the kiln body.
