(1)The dry wet material is transported to the hopper by a belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. (2)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 that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, forming a countercurrent contact with the material. There are also heat carriers and materials flowing together into the cylinder.
(3)As the cylinder rotates, the material moves to the lower end under the action of gravity. During the forward movement of the wet material in the cylinder, it directly or indirectly receives heat from the heat carrier, allowing the wet material to dry and then be sent out through a belt conveyor or screw conveyor at the discharge end.
(4)There is a board installed on the inner wall of the cylinder, which is used to pick up and scatter the material, increasing the contact surface between the material and the airflow, and improving the drying rate.
(5)Heat carriers are generally divided into hot air, flue gas, etc. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials carried in the gas. If it is necessary to further reduce the dust content in the exhaust gas, it should also be discharged after passing through a bag filter or wet dust collector
