Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material,

Coal slurry  Rotary dryer working principle:

One is leading materials part: wet material  enter this area ,contact with high temperature and hot hot blast and evaporate water rapidly.The material is lifted up by lifting blade ,and is lead to next working area before being caked.

The Second is cleaning area, wet material in this area have been lifted up by lifting blade, the material easy to be caked on the drum wall when they fall down.due to the design of the cleaning device, it is very reasonably clean-up adhesion of the wall materials ,In the process,Cleaning device also play the role of breaking the agglomerate materials, increasing the heat exchange area, improve  the speed rate of drying.

The Thrid is oblique lifting blade part, ,wet material in this area has shown a low-water loose status, materials in this area have not been caked,through heat exchange, materials reach the required water status,enter final discharging part, the drum in this area do not have lifting blade,the material in this area rolling and sliding to to discharging part to complete the drying process.

 The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation, and convenient and reliable operation; Therefore, the consumption of the coal and the electricity is lower than the common ones. While the production capacity is higher than 10-15%.
