The screen of cyclone screen is cylindrical and placed in the machine body. After passing through the spiral conveying system, the materials are mixed with the air flow and atomized into the screen barrel; The materials are subjected to centrifugal force and cyclone propulsion force through the wind wheel blades in the mesh drum at the same time, so as to force the materials to spray through the mesh and be discharged from the fine material discharge outlet. The materials that cannot cross the mesh are discharged from the coarse material discharge outlet along the mesh drum wall. Feature introduction 1. The whole machine has the advantages of small volume, light weight, stability, no vibration, low noise, good tightness and high efficiency; 2. Simple installation and convenient operation; 3. It can be used with single machine or multiple machines, and can operate continuously for a long time; 4. The screen is washed by the cyclone and can be cleaned automatically; 5. Redispersion function for agglomerated materials; 6. The new type of outer spherical bearing prolongs the service life; 7. The machine can be matched with the pneumatic conveying system and directly connected into the air path to save resources; 8. New design: the gas protection system can deliver the purified air to both ends of the equipment, which can effectively reduce the temperature produced by the equipment during operation; Form a gas isolation layer for the bearing, so as to eliminate the entry of dust, effectively prolong the service life of the bearing, reduce the maintenance frequency and improve the work efficiency; 9. Can be specially designed; Mesh drum rotation system to meet special needs.
