Dryer is widely used in mineral processing, building materials, metallurgy, and chemical industry etcs ; drying a certain humidity or particle size of materials. The dryer has strong adaptability to materials, can dry all kinds of materials, and the operation is simple and reliable.
working principle
In the process of drying: wet material is sent to the hopper by belt conveyor or bucket elevator, and then the feeder through the hopper enters the feeding port through the feeding pipe. The inclination 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 slightly inclined to a horizontal line.The material is feeded from the higher end, the heat carrier enters from the lower end and is in contact with the material in a countercurrent, and also the heat carrier and the material flow downstream into the cylinder body. A material lifting plate is installed on the inner wall of the cylinder body, and its function is to lift up and scatter the material, increase the contact surface between the material and the air flow, increase the drying speed and promote the material advance.
