Technical data

  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 need to further reduce the dust content of the exhaust gas, you should also discharge it after passing the bag filter or dust collector.

 Rotary drum dryer is the most common and widely used drying machine in mining equipment.Suitable for dry metal and non-metallic ore magnetic separation, gravity separation, flotation concentrate and cement industry clay and coal mine industry slime.It is characterized by high productivity and easy operation.Rotary drum dryer cylinder body is a horizontal rotary cylinder, its internal front to back welding with a staggered array of different angles of various types of plate, rotary kiln body according to the needs of different types of firebrick, in order to prevent the feeding end with a door ring and spiral plate.It has the advantages of reasonable structure, excellent production, high output, low energy consumption and convenient operation.
