2015 new rotary drum dryer for fertilizers for mining from China zhengzhou

      2015 brand new gas sand dryer  rotary drum dryer for mining from China zhengzhou

1.      rotary drum dryer

      rotary drum dryer   is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, etc. This 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 (generally 350-380°) of the rotary drier.

2.Components of     rotary drum dryer   : 
       rotary drum dryer   is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover and so on. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, which is of functions like guiding, current-sharing, and material raising. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.

3.Working Principle of    rotary drum dryer   :
The auto-combustion device provides heat resource for our 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.
