Gyratory screen is one precise sieving machine, the screening box do the reciprocating movement of forward and backward under the action of inertial forces, which from driving unit’s force rotated around the dead axle. The materials on the screening mesh surface of Gyratory screen do the directional jumping movement. This movement effectively reduced the dynamic-static ratio and dynamic load, and there is automatic cleaning device under the screening mesh.

Gyratory screen is widely used in fertilizer, chemical industry, metallurgical, ceramsite, refractory materials, grain, abrasives, mining and other industries which are accurate screening.

1. No vertical vibration, the screening mesh service life is longer (6~12 month)
2. There are cleaning unit for each layer, no blocking on the screening mesh, extending the operating period.
3. As adopting of gyratory reciprocating motion, the distribution state of materials is improved obviously, thus the effective utilization rate of screen surface is improved, and finally the screening efficiency is improved, and the powder content in finished materials is reduced.
4. Fully enclosed structure, no dust pollution, improving operator’s working environment.
5. The dynamic load to foundation is very small.
