The gyratory sifter is an advanced industrial screening separator and high-performance gyratory industrial screening machine generating a gyratory vibration motion close to level plane at low angles in a reciprocating side to side motion.
This unique industrial gyratory sifter was designed to provide a cleaner cut of materials while still allowing higher screening capacity.
The Gyratory Sifter can increase your plant’s productivity by reducing the costs associated with routine maintenance and unscheduled repairs, which means fewer production outages and fewer instances of pulling employees away from other duties for unscheduled maintenance.
It all adds up to less frustration, greater productivity, and lower production costs.
The working principle of the gyratory screen machine is through the design of the eccentric structure of the sifter and the screen surface with a certain inclination angle, so that the materials make a uniform swing reciprocating motion on the mesh cloth. The materials quickly pass through the screen mesh, greatly improving production capacity and screening efficiency increasing longer stroke, the material travels farther, the screening accuracy is high, and the optimum mechanical structure design can avoid damaging the material's own characteristics.
Material trajectory: The material makes a horizontal circular motion while feeding, during the movement, it gradually changes to an elliptical motion and finally adjusts to an approximately reciprocating linear motion at the discharge port. Typical application industries include food, urea compounds, diammonium phosphate, silicon alloy particle, soda ash, glauber's salt, graphite, PVC powder, activated carbon, abrasives, wood cores, tobacco and tea, etc.
The Gyratory Reciprocating Motion gradually diminishes along the length of the machine to an elliptical path and finally to a nearly straight line motion at the discharge end.
The gyratory motion at the feed end of the machine immediately spreads the material across the full width of the screen surface to maximize screen utilization.
Meanwhile, the motion stratifies the material, causing the fines to sink down against the screen surface. Particles appreciably smaller than the openings quickly pass through at this part of the screen.
As the circular motion diminishes into an elliptical path, the gentle near-horizontal in motion causes the particles closer in size to the screen mesh to fall through the mesh openings, these particles are known as near-size particles.
The nearly linear reciprocating motion at the discharge end of the Screener removes those particles closest in size to the mesh openings while gently conveying the oversize material off the screen.
