Work Principle

The wet material is sent to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe through the feeding machine of the hopper. The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and there are also the heat carrier and the material flowing into the barrel together. As the cylinder rotates, the material moves to the lower end by gravity. During the forward movement of the wet material in the cylinder, the heating medium is directly or indirectly heated, so that the wet material can be dried, and then sent out at the discharge end through a belt conveyor or a spiral classifier。
