Overview of Bentonite Clay Rotary Dryer
The mineral raw materials like bentonite, clay, kaolin, etc. contain a certain amount of internal moisture due to long-term deep buried in the ground. So the initial moisture needs the rapid drying dehydration treatment, to meet the industry standards. Zhengzhou Dongding Machinery Co., Ltd. developed a series of mineral dryer, which are very good solution to this problem. The production line uses high temperature drying process, not only greatly reducing the operating costs, but improving the overall economic benefits.
Bentonite Clay Rotary Dryer Working Principle
Firstly, wet material is crushed by the crushing machine, then transported to the rotary drum dryer by the belt conveyor. Because of the inclination of drum dryer, material with hot air moves to the end of dryer body, during which process wet material gets fully contact with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The left materials mixed with dust continue go into the cyclone dust collector and the bag dust collector in sequence, where the dust will be collected. Lastly, with the function of induced draft fan, the left material will discharged through the conveyor.Features of Bentonite Dryer Machine
1. Large processing capacity, less fuel consumption, low drying costs.
2. Downstream drying mode, hot air and wet materials are from the same side into the dryer, obtaining a high evaporation intensity and high thermal efficiency.
3. New feed and discharge device, eliminating the feeding blockage, discontinuous, uneven and recharge, reducing the load of dust removal system.
4. New internal structure, eliminating the adhesion phenomenon of the inner wall.
5. Wide application. The system is mainly suitable for materials with high water content, fine granularity and large viscosity.
