Coal Dryer

Coal Slime Rotary Dryer Introduction Coal slime has high water content, large viscosity, small particles, not easy to transport, its economic value is low, very unstable, easy to weathering, According to these characteristics, Dongding has developed a special coal slime dryer, strictly control the drying temperature of the dryer, pressure, air volume and speed. Besides, it also equipped with different forms of feeding device, cleaning device, crushing device, fully realizing heat exchange and thermal transformation, improoving the drying efficiency and heat utilization rate, and reducing the emission of exhaust dust, which is energy saving and environmental protection. Coal Slime 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 with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The left material mixed with dust continue goes 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. Coal Slime Rotary Dryer Features 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. According to the properties of different coal slurry to change the operating parameters, so that the material can be evenly transmitted, achieving more adequate heating exchange. 4. New feed and discharge device, eliminating the feeding blockage, discontinuous, uneven and recharge, reducing the load of dust removal system. 5. New internal structure, eliminating the adhesion nomenon of the inner wall. 6. According to user requirements to control product granularity and moisture, finial products can be about 10%. 7. Wide application. The system is mainly suitable for materials with high water content, fine granularity and large viscosity.
