The centrifugal sifter is a new kind of particle grading sieve machine. It has the advantages of high production efficiency, simple structure, low noise, easy operation, good sealing, no dust flying, convenient maintenance and so on. And it is widely used in chemical, pharmaceutical, food and other industrial fields.

Working Principle

The machine is made up of motor, base, housing, material in and out propelling device, screen barrel etc.

When it works, the material enters from the feed inlet at the upper end of the housing, and the rotating screw feeds the material into the screen barrel.

Material into the screen barrel is driven by rotating scraper, impacting the cylindrical screen mesh under the action of centrifugal force and cyclone propelling force, making the material smaller than the mesh through the screen and discharge from the fine outlet.

The coarse powder is bounced back by the screen, moving forward and discharging from the coarse outlet under the action of cyclone propelling force and scraper, thus completing the entire screening process.

The equipment can be divided into general type, convenient type and high efficiency type according to the structure.

The convenient type applies to the food and pharmaceutical industry. The internal weld arc treatment is for easy cleaning, and the structure is easy to disassemble.

The screen mesh barrel of the high efficiency type rotates, making the screen utilization rate higher, and increasing the capacity and the screen service life.


  1. Small size, light weight, steady and no vibration, no noise, good sealing performance, no dustand high efficiency.
  2. The shell structure is novel. Easy to control. Simple installationand low requirement forlaying foundation.
  3. It can be used by single machine or matching with multi-machines. Long time continuous operation. Safe and reliable.
  4. The screen mesh is washed by the cyclone and can be automatically cleared. It can be equipped with a variety of material screens: stainless steel wire mesh, stainless steel or carbon steel punching hole mesh. Long service life. The nylon fiber screen has anti-static and automatic cleaning function.
  5. Screening and crushing into one. It has the  recrushing function to the caking material.
  6. Without static electricity in the operation. The friction in the screening process is small. Not easy to produce static electricity.
  7. This machine can be matched with the pneumatic conveying system, directly connected into the wind path, saving 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. The gas isolation layer is formed on the bearing, thereby preventing dust from entering, effectively prolonging the service life of the bearing, reducing the maintenance frequency and improving the work efficiency.
