Rotary cooler

　　The dried wet material is transported to the hopper by a belt conveyor or bucket elevator. It then enters the feeder through the feed pipe and into the feed end. The feed pipe's slope should be greater than the material's naturalinclination to ensure smooth material flow into the cooler. The cooler cylinder is a rotating cylinder slightly inclined to the horizontal. Material is fed in at the higher end, while the heat carrier exits at the lower end, interactingwith the material in countercurrent flow. Sometimes, the heat carrier and material enter the cylinder together. As the cylinder rotates, the material flows by gravity to the lower end. As the wet material moves forward within the tube, it receives heat directly or indirectly from the heat carrier, cooling it. It is then discharged at the discharge end via a belt conveyor or screw conveyor. A lifting plate is installed on the inner wall of the cylinder to liftand lower the material, increasing its contact surface with the airflow, thereby increasing the cooling rate and promoting material forward movement. The cooling medium is generally composed of cold air and other media. After the heat carrierpasses through the cooler, a cyclone dust collector is typically required to capture any material carried in the air. If you need to further reduce the dust content in the exhaust gas, it should also pass through a bag filter or wet dust collector before discharging.
