Rotary dryer machine

Rotary dryer is one of the traditional drying equipment. It has a reliable operation, flexible operation, strong adaptability, and large processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin, sugar In other fields, the diameter is Φ1000-Φ4000, and the length is determined according to the drying requirements. In the center of the rotary dryer, it is possible to avoid adding a scattering mechanism, and the wet materials entering the drying cylinder are repeatedly picked up and dropped by the copy board on the drum wall and are broken into fine particles by the scattering device during the falling process. , The specific area is greatly increased, and it is fully in contact with hot air and dried.

The machine is mainly composed of a slewing body, lifting plate, transmission device, support device, and seal ring. The dryer is a cylinder that is slightly inclined to the horizontal direction. The material is added from the higher end. The high-temperature hot flue gas and the material flow into the cylinder. With the rotation of the cylinder, the material runs to a lower level due to gravity. One end. A copy board is installed on the inner wall of the cylinder to pick up and sprinkle the material so that the contact surface between the material and the airflow is increased to increase the drying rate and promote the material to move forward. The dried product is collected from the bottom of the bottom.

Scope of application:

1. Chemical industry, miner, metallurgy and other industries, such as ore, slag, coal, metal powder, clay, diatomaceous earth, kaolin.

2. Agriculture, feed, fertilizer industry, such as straw, forage, leaves, fish meal, corn sauce, starch residue, lees, medicinal residue, fruit residue, soy sauce residue, bagasse, peat, organic compound fertilizer, sludge, aquatic product waste, Food factory waste, slaughterhouse waste, organic fertilizer, inorganic fertilizer, ammonium phosphate fertilizer.

3. Dry powdery and granular materials with special requirements. Such as various crystals, light calcium carbonate, activated clay, magnetic powder, graphite, inorganic mud, clay, lime mud, ore mud, phosphate slag, red mud of aluminum plant.

4. Materials that require low-temperature drying and continuous drying in large quantities.

The main purpose:

The combined three-cylinder dryer is mainly used for drying granular materials in a certain humidity range, such as yellow sand used in the dry mortar industry and various specifications of sand used in the foundry industry. Blast furnace slag for the building material cement industry. Small particle size clay, used in the chemical industry for small particle materials that cannot afford chemical changes, and are not afraid of high temperature and smoke pollution. According to the requirements of different industries for the final moisture content of the dried material, the moisture content of the dried material can reach 1-0.5% or less.

The materials entering the dryer should be non-stick walls and poplar boards. The temperature of the gas entering the dryer for heat exchange should not be higher than 750 degrees Celsius. If there are special requirements for high-temperature drying, the inner cylinder and poplar board at the entrance of the dryer can be made of heat-resistant steel.
