Gyratory Screen

Overview of Gyratory Screen:
Gyratory screen is also called gyratory screener, gyratory separator, gyratory sifter, gyratory screening machine, planar rotary screen, plane rotary screen, rotary flat sieve, flat screen, square precision screening machine, reciprocating screen etc. Driven by an ordinary motor, this screening machine drives the eccentric wheel to do gyratory reciprocating motion. It is often used for screening quartz sand, urea, fertilizer, resin, glass bead, wood pellet, sodium carbonate, melamine, tea, sugar, salt, petroleum coke etc.
 
Working Principle of Gyratory Screen:
The gyratory reciprocating motion of gyratory screen begins with a circular motion at the feed end, gradually diminishing along the length of the machine to elliptical movement in the middle, and finally to an almost straight-line motion at the discharge end.

 
1.Circular motion at the feed end
The gyratory movement at the feed end can quickly complete the material’s spreading, stratifying, separating and moving forward across the full width of the screen surface.
 
2. Changing to elliptical motion at center
The long-stroke elliptical movement can enhance material stratification, improving the screening capacity and sieving effect of near-size particles.
 
3.Straight line motion at the discharge end
The linear sifting motion at the discharge end has almost no particles jump vertically, which ensures that the material is in constant contact with the screen surface.

Advantages of Gyratory Screen:
1. unique gyratory reciprocating motion
2. automatic screen surface tension device
3. ball cleaning system
4. double-balanced motor system
5. convenient and quick compensating clamps for head cover

Features of Gyratory Screen:
1. Super large capacity and high screening accuracy, suitable for industrial continuous screening.
2. The effect of anti-clogging screen mesh blinding is good. Especially suitable for the screening of materials which are easy plugging and sticking the screen mesh.
3. Screen service life is long. It is 5~100 times than the ordinary vibrating screen.
4. The soft running does not damage the particles original structure of the material.
5. Three types of screen tensioning spring clips and screen side pull mode. Easy to remove and replace the screen.
6. It is not easy to generate static electricity, especially suitable for the screening of materials those are flammable and explosive, and easy to generate static electricity.
7. Smooth operation, no special requirement for the plant.
8. Totally enclosed structure, no dust, low noise to 70 decibels.
