SFJH Rotatory Grading Sifter Introduction

The rotary vibrating screen is mainly used for pre-cleaning or grading of raw materials in milling, feed, chemical, food, oil, and other industries. By replacing the sieves of different apertures, it can granular materials such as wheat, corn, rice, oilseeds, etc.

In addition, they can also be widely used for screening and grading feedstuffs and finished products in cereal and food processing, chemical engineering, sugar engineering, mining, and paper production industries.

SFJH Rotatory Grading Sifter Advantages

1. It is suitable for the classification of granular and crushed materials, the secondary recovery and crushing process, and the cleaning and classification of some granular and powdery materials.

2. Simple and convenient screen pressing mechanism, quick screen change.

3. The transmission device operates in a gearless transmission mode, without oil lubrication, to avoid oil leakage.

4. Using counterweight, small vibration, and low noise.

5. The tail elastic support design effectively assists the vibrating screen to maintain balance, reduces noise, and greatly improves screening performance.

6. Optional double-layer sieve, triple-layer sieve, double-feed double-layer sieve (can be customized according to customer requirements).

SFJH Rotatory Grading Sifter Working Principle

The power is transmitted to the driving device by the motor through the V-belt, and the driving device drives the screen body to a certain slope. The driving device is equipped with an eccentric device so that the motion trajectory of the screen body from the feed end to the discharge end gradually changes from horizontal circular motion to elliptical motion, and finally to approximate reciprocating linear motion. The material enters the sieve body from the feed port, and is quickly and evenly distributed on the entire screen surface width under the action of the circular motion of the feed end of the sieve body, and automatically grades. Therefore, the material with a smaller particle size below the material layer is quickly screened, while the material with a larger particle size above moves to the lower end (discharge end) along the slope of the screen body. It is used in poultry feed, chicken feed, bird feed, cattle feed, sheep feed, pig feed manufacturing plants, and woody biomass pellet production plants.
