Rotary dryer, also known as rotary dryer, is a type of dryer that processes large amounts of materials. Due to its reliable operation, high operational flexibility, strong adaptability, and large processing capacity, it is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, pharmaceutical and mining industries.

working principle:

Dry and wet materials are transported to the hopper by a belt conveyor or bucket elevator, and then enter the feeding end through the feeding pipeline through the feeding machine of the hopper. The slope of the feeding pipeline should be greater than the natural inclination angle of the material, so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined from the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, coming into counter current contact with the material. There are also cases where the heat carrier and the material flow together into the cylinder. As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material inside the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry, and then is sent out through a belt conveyor or screw conveyor at the discharge end.
