It is generally suitable for the granular materials and also used for the partially mixed materials with dry sticky paste materials or materials with high water content.
Principle of operation
During the drying process, the wet material is added from the higher, the heat carrier from the lower end to enter into the drying drum, then it contact with the wet material, As the rotating material of the cylinder is moved by gravity to the lower end.
Different heat sources can be used depending on the requirements of the drying product. Such as: gas producer, direct heating hot blast stove, indirect hot blast stove, heat transfer oil, electric heating, steam, etc.
1. Large production capacity
2. Wide application range
3. Small flow resistance
4.Widely used for drying sand, mineral powder, slime, chicken manure, cow dung, etc
