Rotary dryer is used for the drying process of materials, which is by far the most widely used drying equipment. It is widely used in building material, light industry, medicine, metallurgy, coal mining and other industries.
Applied Materials: gypsum, sawdust, wood shavings, sand, slag,clay,etc.
Capacity:1.9-76TPH
Rotary dryer is used for the drying process of materials, which is by far the most widely used drying equipment. When compared with the ordinary drying equipment, the heat and material of rotary dryer enters into the drying machine at the same end. The biggest characteristic of rotary dryer is that it has spiral lifter in the drying machine. In the drying process, lifting plate makes the material do rotary motion inside, and the material is dried in the process of hot air. In contrast, the drying effect of rotary dryer is more uniform. Rotary dryer also has other names, such as rotary drum dryer and rotary dryer plant.
Rotary dryer is widely used in building material, food, light industry, medicine, metallurgy, coal mining and other industries. It can be adapted to the drying of the clay, gypsum, coal, slag, coal gangue, mixture, sand, iron and other raw materials. In addition, rotary dryer is also used to dry raw materials in the production process of chemical fertilizer.
1. Rotary drying makes the material have full contact with the hot air, so that the drying of material is more uniform.
2. The application scope of rotary dryer is wide, which can handle a variety of materials.
3. The speed can be adjusted, and the drying degree controllable.
4. Short drying time, large processing amount in unit time, and its efficiency is 50% higher than the ordinary dryer.
5. Small heat radiating area, good heat utilization rate, which reduces the production cost.
6. High degree of mechanization, simple and convenient operation.
7. Good sealing effect, clean working environment.
8. Fine structure, low failure rate.
9. The motor has dust-proof and anti explosion functions.
1. Pay attention to the working load of equipment during the running period, which generally does not exceed the rated 80%, and it should be arranged the suitable workload.
2. After the running period, it should be conducted a comprehensive maintenance.
3. Usually check the lubrication oil of the required parts and make record.
4. Before and after use of the machine, keep it clean; timely tighten the loose parts.
5. If there is any problem, immediately stop and check, before eliminating the failure, it should not continue to work.
6. Follow the instructions and training from rotary dryer manufacturer.
