Working Principle of Sand Dryer

  Sand will be sent to hopper by belt conveyor or bucket elevator. Then, materials will enter charging door through charger of hopper. The inclination angle of charging pipe should be larger than natural inclination angle of materials, which will make materials enter dryer smoothly. The body of sand dryer is a rotary cylinder which forms a small inclination with horizontal level. Materials will enter from the higher end and heat carrier will enter from the lower end. There will be a countercurrent flow formed between materials and heat carrier. Sometimes, materials and heat carrier will enter the drying cylinder together. With the rotation of cylinder, materials will come to the lower end by the function of gravity. In the process of moving forward, materials will be heated by heat carrier directly or indirectly. Then, materials will be sent out by belt conveyor or screw conveyor. There are lifting plate installed in the inner wall of cylinder, which can increase the contacting surface between materials and air flow. Accordingly, the drying and moving speed can be improved. Generally, heat carrier consists of hot air and flue gas. After the heat carrier’s passing by dryer, a cyclone dust collector is always needed to catch materials contained in air. If you want to reduce exhaust gas further, you can discharge the exhaust gas after bag filter or wet precipitator.
