Rotary Drier is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature
Rotary drier is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. rotary drier is designed with the best working conditions, which enables it to save energy and increase productivity compared with common dryers.
Rotary Drier Working Principle:
The device provides heat resource for rotary drier, which adopts down-flow heating method. When the mineral materials are fed into the cylinder, it flows down as a result of gravity. Meanwhile, they are repetitively scattered in the air so that they are in full contact with the hot air. The material is thus dried gradually.
