  • The internal adopts assembled structure, which has improved the accuracy of the equipment. It is easy to transport and stall.
  • According to the characteristics of different fertilizers, we have arranged the second granulation zone reasonably so as to improve the granulation effect.
  • Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption.
  • Temperature induction monitor, uniform vibration and airproof setting improve performance and productivity efficiently.
  • The assorted combustion furnace is a type of energy-efficient and equipped with greenhouse.

Working principle of rotary dryer:

 

The auto-combustion device provides heat resource for our Industrial 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 dried gradually
