They also fit into stationary crushing plants or where headroom is limited. Installed beneath crushers, they eliminate surge loads in delivery conveyors while protecting conveyor belts. Our larger feeders utilize a heavy-duty, wide flange beam construction which provides a sturdy, rigid frame that is resistive to twisting. This allows you to choose the model that best suits your needs and provides you with maximum production rates.
All grizzly designs feature adjustable, tapered grizzly bars.
Pioneer installs the most rugged bearing offered in the industry, designed to perform with excellence under the toughest operating conditions. Feed material is moved forward and upward in an elliptical path. The resulting turning motion of the material provides high capacity and excellent scalping action as the material is turned to expose all sides to the grizzly openings. Fines are shook loose by this motion and drop through the grizzly to be by-passed. Pioneer utilizes precision engineered, spur type, case hardened timing gears to insure exact synchronization and maximum effectiveness for a long service life.
