Working principle of plane rotary screen

The working principle of plane rotary screen is introduced. Why choose Zhaoyang plane rotary screen?

As an enterprise specializing in the production and research of plane rotary screen, Zhaoyang screening technology expounds the working principle of plane rotary screen in detail as follows:

Application of plane rotary screen

The plane rotary screen can be used for filtering large particles, removing dust and small particles, and grading screening.

(1) Filter large particles and screen them, mainly to screen out oversize particles and other impurities in the material. Generally, oversize particles will not exceed 10% of the feed content, and most of them will be less than 5%. After a small amount of oversize particles are screened out, the undersize is the required finished granular material.

(2) Dust removal and fine material screening, which mainly screens out small unqualified materials smaller than the size of finished materials, and the ratio of fine materials is generally less than 10% of the total feeding amount. After removing fine materials, the screened materials are even the required finished materials.

(3) Classified screening, that is, screening according to the required material particle size. The plane rotary screening machine can be a single-layer screening machine or a multi-layer screening machine, and the material size distribution can be evenly distributed or greatly different.

Main characteristics of plane rotary screen

(1) The plane rotary screen has three trajectories during operation, the feeding end is round, the middle section of the screen is oval, and it moves in a straight line near the discharge port.

When the material falls on the screen of the screening machine, under the strong circular revolving motion of the screen itself, the material is quickly separated laterally along the screen surface until the material layers are completely separated according to the width of the screen surface.

After the first stage of material distribution, the material layer of the material is suitable for screening, and at this time, the movement track of the material changes from circular to elliptical, and the material can be fully screened at this stage.

After the first two stages of screening, the screening work of materials has basically ended at this moment, the movement trajectory of materials has changed from ellipse to straight line, the movement trajectory of materials has become shorter, and materials quickly flow into the discharge outlet of rotary screen and are discharged.

(2) Large swing

The amplitude of the plane rotary screen is between 40-90mm, and the running track of the material is longer under this swing. In addition, the plane rotary motion of the plane rotary screen greatly increases the running distance of the material and effectively increases the throughput of the screen.

(3) The material always runs on a plane, and there is little vertical jumping movement. The material clings to the screen surface, and the material smaller than the screen aperture can pass at any time.

(4) Small inclination angle

The installation inclination angle of the screen plate of the plane rotary screen is generally 4-8 degrees, and the projection size of the screen hole on the horizontal plane is very close to the actual screen hole size, so that the screened material is closer to the actual required size.
