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. 

Benefits

1. Adopting multi-combination material lifting device: the dryer designed and manufactured by our company has made many technical innovations in the material lifting device system, and adopted new multi-combination material lifting device, which overcomes the "wind tunnel" phenomenon of the traditional dryer.High thermal efficiency, reduced coal consumption by about 20%, and is suitable for various combustion furnaces, such as high temperature fluidized bed furnace, pulverized coal injection furnace and artificial coal feeding furnace. 

2. The transmission gear adopts pin column exchangeable gear, which replaces the traditional cast steel gear, saves cost and investment,and greatly reduces maintenance cost and time; has larger production capacity and simple structure, easy and continuously operation 。The dryer also has the advantages of few faults, low maintenance cost, widely application, and can be used to dry granular materials, which is also beneficial to the materials with large adhesion.
