Smooth gyraytory screen for a variety of materials

Working Principle

Judging from the trajectory of the sieve body, that is, the movement of the sieve box, the rotary screen is also called the large-scale re-screening. The vibration force generated by the driving device is an inertial force that changes the axis and the direction is changed regularly. The essence is The reciprocating inertial force formed by the eccentric rotating the shaft. According to the structural characteristics and working principle of the rotary screen, the screen surface is generally horizontal or slightly inclined. The working principle of the rotary sieve is as follows: after the sieve machine is started, the sieve shaker, that is, the sieve box, reciprocates back and forth under the action of inertial force, and the screen box drives the sieve surface to periodically shake, so that the material on the sieve surface is matched with the sieve box. During the directional jump movement, the physical space smaller than the sieve aperture falls into the lower layer through the sieve hole, and becomes the undersize material. The material larger than the sieve aperture is discharged from the discharge opening after continuous tumbling jump movement, and finally the screening work is completed. 

Product Application

(1) Chemical industry: fertilizer, soda ash, calcium powder, resin, melamine, etc.

(2) Food: sugar, salt, starch, milk powder, etc.

(3) Metallurgy: metal, magnetic materials, etc.

(4) Building materials: paints, refractories, etc.

Main Features

1. No vertical vibration, long life of the screen (6-12 months);

2. Each screen is equipped with a screen anti-blocking cleaning device. The screen does not block holes and prolongs the operating cycle. The screening machine cleans the screen continuously under continuous working conditions.

3. Due to the principle of plane rotation, the distribution state of the material is obviously improved, thereby improving the effective utilization ratio of the screen surface, finally improving the screening efficiency and reducing the powder content in the finished material;

4. The dust-free pollution of the fully enclosed structure improves the work environment of the sales assistant;

5, the dynamic load on the foundation is very small
