DW series belt dryer

The material to be treated is distributed on the conveyor belt through an appropriate laying mechanism, such as star distributor, swing belt, crusher or feeder. The conveyor belt passes through a channel composed of one or several heating units, each heating unit is equipped with an air heating and circulation system, and each channel has one or several moisture drainage systems. When the conveyor belt passes through, Hot air from the top down or from the bottom up through the conveyor belt on the material, so that the material can be evenly dry. The material is evenly spread on the net belt by the feeder. The net belt is generally made of 12-60 mesh stainless steel mesh, which is moved in the dryer by the driving device. The dryer is composed of a number of units, each unit of the hot air independent circulation, part of the exhaust gas is discharged by the special exhaust fan, the exhaust gas is controlled by the regulator, the hot gas from the bottom up or from the top down through the net belt covered with materials to complete the process of heat and mass transfer, take away the material moisture. The net belt moves slowly, the running speed can be adjusted freely according to the temperature of the material, and the finished products after drying fall into the feeder continuously. The upper and lower cycle units can be flexibly equipped according to the needs of users, and the number of units can be selected according to the needs.
