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.
