What is a gyratory screen?

The Gyratory Vibrating Screen (also called Gyratory Screener, Gyratory Screen, Gyratory Sifter, Gyratory Separator, Gyratory Separator machine) is a new high-standard screening equipment, also known as Swing vibrating screen.

Gyratory sifter is driven by a motor with an eccentric mechanism operation, the screen box section swing in the horizontal plane as the plane through the three solutions, the trajectory of the screen box near the traditional manual screening trajectory sieve

Gyratory Vibrating Screen of screening machine is fully sealed structure, the overall structure is more compact, screening efficiency, high utilization screen, long screen life, low noise, can be installed hanging, seat type, easy to use, no pollution, is a piece of ideal environment-friendly screening equipment. It can be widely used in chemical, ceramic, pharmaceuticals, metallurgy, mining, food, and other industries in the accurate classification of fine materials.

Principle of Gyratory Sifter

The materials do the reciprocating-gyratory motion along with the gyratory sifter running, and there is no vertical jump during the gyratory screen running period, the little size material will go to the bottom of the flow bed along moving forward, the material particle will pass the mesh aperture when the particle size is less than the gyratory separator aperture size. The reciprocating gyratory motion will make the material flow bed touch the screener mesh surface for a longer time to increase the screening efficiency.

The reciprocating gyratory motion of the Gyratory vibrating screen will spread the material flow bed evenly along with the screener mesh bed after the material fall into the inlet, the material flow bed will be very thin after being spread, it is good for material screening, and the material screening precision and capacity will be increased.

The screen deck of gyratory sifter equipment consists of mesh, spring clamp, ball trays, and self-cleaning balls. The self-cleaning balls jump ceaselessly along with gyratory screener operation, the ball could hit the screen mesh in order to let the mesh vibration, so the material blocked in the mesh aperture or adhered to the mesh surface will be cleaned out, it could make sure the aperture ratio so guarantee the screening efficiency.

The gyratory sifter does not have vertical vibration, so it does not have much load request on the base foundation, it is much lower than the vibration model screener, so the gyratory screener could save steel structure cost, the customer does not need to consider the install load limited.

Feature of Gyratory Screener

  • Reasonable design, mature technology, easy installation and maintenance, wide application scope;
  • High screening efficiency, precision, and processing capacity;
  • sieve box tranche adjustment can swing stroke.
  • The vibrating screen below to play with high elasticity vibration makes the material not easy to block;
  • Good sealing and balance weight can provide slight vibration and low noise, and environmental protection.
  • Combination of Circle, elliptic, linear motion, high screening effect. Suitable for various material screening
  • Equipped with automatic tension and automatic cleaning sieve net installation system which can make the screen mesh long service life and high efficiency, change the screen mesh conveniently.
  • A reinforced base ensures the equipment operation machine more balance, can also according to the actual site conditions the perching hook to meet customer’s reform needs
  • Improve wire rope hanging structure, to avoid steel wire wear
  • Two or three deck screen frame designs can be chosen.
  • Used for powder or granule feed screening and grade, can also be used for avoidance of raw materials in feed factory, the grading of intermediate products after second smashing.
  • Workforce on the sieve material particles is small, the material by gravity through the screen, so the screening process small damage to the material, particularly suitable for the convection resistance, brittle material for screening.

Advantages of the gyratory sifter

Reciprocating Gyratory Motion

Gyratory sifter with Gyratory reciprocating motion provides efficient distribution, stratification, and sifting resulting in higher yields and less rejection of good material.

Easy Operation

Stable operation, high performance, reduce the screening costsThe self-cleaning ball could avoid the mesh blocked.

Easy Sifter Mesh Replacing

The mesh is fastened on the deck vis a spring clamp, it is easy to change the mesh

Wearable and Reliable

High quality and wearable structure featuring abrasion and corrosion-resistant stainless steel.

Application of gyratory screen

About the separation equipment, we usually call it a plant rotary screen because its moving track is gyratory along with a circular on one plane.

It has been successfully applied to screening granular urea in fertilizer plants.

But it is also used to screen other thousands of different materials and is suitable for many industries and applications as below:

Chemical, carbon product, wood chips, grain cleaning, mineral, fertilizer, steel shot, clay, animal feed, etc. wet river sand, sea sand, sugar, refractory material Gyratory Vibrating Screens, Etc.
