The working principle of Sand Dryer
Sand sent to the hopper by the belt conveyer and bucket elevator, and the angle of materials, so that material flows into the sand dryer. Dryer cylinder is a rotating cylinder. Material from the high-end to join, heat carrier from the low-end entry, countercurrent contact with material, also have heat carrier and material flow into the cylinder together. With the rotating cylinder materials by gravity run to the lower end. Wet material in the cylinder body to move forward, heat by heat carrier directly or indirectly, so that the wet material to be dried, then at the discharge end through a belt or a screw conveyor send out. In sand dryer inner wall of the cylinder is provided with a copy board. Its role is to bring up material then down, increasing the contract surface of material and gas flow, in order to improve the drying rate and promote material progress. Heat carriers are generally divided into hot air, flue gas. Heat carrier through the dryer, then the material in the gas was collected by cyclone dust collector.
