High moisture content in raw coal will lead to low calorific value, insufficient combustion and other adverse conditions, has a negative impact to the economy and safety. Zhengzhou Dongding has developed a raw coal dryer production line in accordance with the features of raw coal in order to improve the quality and storage and transportation performance of raw coal.
Firstly, wet material is crushed by the crushing machine, transported to the screw conveyor by the belt conveyor, then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.
1. The hot flue gas directly contacts with the materials, sufficient heat exchange and high production capacity.
2. Reasonable system configuration, it can use part of coal powder drying for fuel production, reduce costs and secondary pollution.
3. The system is equipped with PLC control system and video monitoring system, with a high degree of automation and simple operation;
4. The system through a unique sealing structure, no leakage, completely solve the sealing difficulties, to achieve a full range of non-oxidation negative pressure operation, eliminate the possibility of lignite combustion explosion, safe and reliable operation;
5. Low investment, low operating cost and and short investment recovery time.
