Three cylinder dryer

Three-cylinder dryer equipment can dry dry mortar, yellow sand, cement slag, clay, coal gangue, mixed materials, fly ash, gypsum, iron powder and other raw materials, widely used in building materials, chemicals, castings, etc. industry.

working principle
The material is fed into the inner layer of the rotary drum of the three-cylinder dryer by the feeding device to achieve the downstream drying. The material is continuously picked up and scattered under the copying board in the inner layer and spirally conveyed to achieve heat exchange. The material is moved to the inner layer. The other end enters the middle layer and is counter currently dried. The materials are continuously raised in the middle layer, and it is a two-step step backwards. The material in the middle layer not only fully absorbs the heat dissipated by the inner drum, but also absorbs the heat from the middle drum. At the same time, the drying time is prolonged and the material reaches the optimum dry state here.
