Rolling Drum Dryer
From Drying Equipment
Rolling drum dryer mainly from the rotary body, lifting plate, gear, support equipment and seals and other components. The utility model has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation. The working principle of the tumble dryer: the dry wet material 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 feeding machine of the hopper.
The slope of the feeding 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 process of moving the wet material forward in the cylinder, the heat supply of the heat carrier is directly and indirectly obtained, so that the wet material is dried, and then sent out at the discharge end by a belt conveyor or a screw machine.
The heat carrier is generally classified into hot air, flue gas, and the like. After the heat carrier is dried, a cyclone is generally required to collect the materials 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 wet dust collector.
