Rotary drum cooler is a new generation of high efficiency cooling machine developed by our staff for many years of compound fertilizer production experience. It is paired with the rotary drum dryer for cooling the fertilizer particles in a certain temperature and particle size during the production process of compound fertilizer. This rotary drum cooler can greatly improve the cooling speed, reduce labor intensity, improve the yield, further to remove part of water and reduces the fertilizer particle temperature. At the same time, it can also be used for the cooling of other powdery and granular materials. The equipment is with compact structure, high cooling efficiency, reliable performance and adaptable to any materials.
The main motor drives the belt and pulley and transform the energy to the driving shaft through reducer, then the counter gears installed on the driving shaft are drove to meet the large gear that installed on the machine body, so that these gears began to rotate to opposite directions to drive the body began to work. The material is added from the feed end to the inner part of the barrel. Under the influence of the draft fan (match with the machine), the air flow in the cylinder body is accelerated, and the lifting plate installed on the inner wall of the whole body continuously turns the material up, so as to achieve the goal of uniform cooling. The cooled material flows out of the discharge port, and the material continues to enter as the motor continues to rotate so that mass production can be achieved.
