How The Dryer Works

The power is generated by electric power, diesel power, wind power, flammable materials, etc., and is heated by the ambient air, and is transported to the surrounding area to reach a proper temperature for dehumidification treatment. The specific process is as follows: the wet material is sent to the hopper by a belt conveyor or a bucket elevator, and then fed through the hopper through the feeding pipe into the feeding end. The slope of the feed pipe is greater than the natural inclination of the material so that the material flows smoothly into the dryer. The dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the lower end, and is in countercurrent contact with the material, and the heat carrier and the material are simultaneously flowed into the cylinder. As the rotating material of the cylinder is moved by gravity to the lower end. During the forward movement of the wet material in the cylinder body, the heat supply of the heat carrier is directly or indirectly obtained, so that the wet material is dried, and then sent out at the discharge end by a belt conveyor or a screw conveyor. A copy board is arranged on the inner wall of the cylinder, and its function is to copy and sprinkle the material, so that the contact surface of the material and the air flow is increased to increase the drying rate and promote the advancement of the material. The heat carrier is generally classified into hot air, flue gas, and the like. After the heat carrier passes through the dryer, a cyclone is generally required to trap the material contained in the gas. If you want to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or the wet dust collector.
