The Rotary Drier is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made of rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
Working principle 1.The material first goes into the inside drum, because there are the spiral shape boards fixed in the drum, when the dryer make rotary working, the spiral shape board will stir the material and make the material move forward. 2.When the material reaches the right side of the drum, it will go into the second drum for further drying. 3.The material then goes into outside drum in the same way, during the drying working process, the material will be dried for three times, so the material can be dried completely in this process.
