This type of cooler is meant for cooling of powder materials with transport achievement up to 100 t/h. Cooler’s wall consists of vertical cylinder shell. The cooling water flows down from outside of the shell. Cooling material is supplied to the lower part of the cooling cylinder on its bottom, where rotor moves by spiral blades. Rotor is driven by electromotor with frequency converter and gear-box. The material is moved to shell circumference by centrifugal force. The material is intensively mixed at the same time, which means high heat conversion between shell and cooled material. This process also prevents possible sedimentation of material on cooler’s wall
