How the Dryer Machine Works

Power is generated by electricity, diesel power, wind power, flammable material power, etc., and the ambient air is heated, transported to the surrounding area, and then reaches an appropriate temperature for dehumidification treatment. The specific process is as follows: the wet material is sent to the hopper by the belt conveyor or the bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the low end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly obtained from the heat carrier, so that the wet material is dried, and then sent out through a belt conveyor or a screw conveyor at the discharge end. A copy board is installed on the inner wall of the cylinder, and its function is to copy and sprinkle the material, so that the contact surface between the material and the air flow increases, so as to improve the drying rate and promote the advancement of the material. Heating medium is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should also be discharged after passing through a bag filter or a wet filter.
