The sand is sent to the hopper by a belt conveyor or a bucket elevator, and then enters the feeding end through the feeding pipe through the hopper feeder. The inclination of the feeding pipe should be greater than the natural inclination of the material so that the material can flow smoothly into the sand dryer. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier (such as hot air, flue gas, etc.) enters from the lower end and contacts the material in countercurrent. There are also heat carriers and materials that flow into the cylinder together. 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 is directly or indirectly heated by the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through a belt conveyor or a screw conveyor. A lifting plate is installed on the inner wall of the sand dryer cylinder. Its function is to lift up and scatter the material so that the contact surface between the material and the airflow is increased to increase the drying rate and promote the material to move forward.
