High-Speed Gyratory Screening

High-speed gyratory screening equipment at BM&M Screening Solutions uses a patented design to deliver higher G-loads and greater screening efficiency than vibratory or conventional gyratory screening systems. The horizontal, circular motion of our screeners maintains more direct contact with the material on the screen, providing better sizing and screening performance. Our screeners are useful for materials like wood, pulp, paper, grain, nuts, corn, pet food, animal feed, powders, and more.

Patented Weight Drive Technology Ensures Effective Screening

The key to our enhanced industrial screening performance is our patented weight drive technology. BM&M’s drives use a stationary shaft and a high-speed eccentric weight that rotates on a bearing assembly to generate an eccentric gyratory motion. Our screening equipment is engineered to, essentially, “rotate around itself”, based on the center of gravity of the machine. This enables our systems to dissipate more energy for more efficient and effective performance.
Competitors’ gyratory screening machines use a more traditional crankshaft design that is inherently limited in the amount of energy it can dissipate and that often fails at high-speeds or under high load. Thanks to our unique design, our gyratory screening equipment is capable of higher speeds and larger strokes (diameter of gyratory movement) that combine to create a higher G-load. A high G-load is critical to the effective screening of any material.
Additionally, the design of other manufacturers’ gyratory screeners generally result in gyratory motion at only one end of the screen—the infeed end usually remains mostly stationary. Our drive units are positioned at the absolute center of the machine, and so create the same screening motion and efficiency over the entire screen surface.
