Vibrating Grizzly Feeder Working Principle
AGICO CEMENT vibrating grizzly feeder is driven by an electric motor and uses a dual eccentric shaft exciter connected by a V-belt to generate a synthesized linear excitation force, thereby forcing the entire unit to vibrate on supporting springs. When the material enters the hopper, vibration serves as the driving force, causing the material to slide and throw inside the hopper, gradually moving forward and achieving the goal of continuous and uniform feeding.

The two eccentric shafts of the vibrating feeder are connected by a pair of gear pairs with a transmission ratio of 1, ensuring that the two shafts rotate at the same speed and in opposite directions. Due to the equal eccentric mass and eccentricity on both shafts, the inertial forces generated during rotation cancel each other out in one direction and superimpose in the other direction, forming a stable directional excitation force that causes continuous vibration of the feeding tank body rigidly connected to the exciter.
When materials pass through the chute, smaller particles can fall directly through the gaps between the grizzly bars on the chute, avoiding entering the subsequent crushing process and playing a pre screening role. This design fully ensures the efficient operation of downstream crushing equipment, avoids unnecessary material processing steps, and further enhances the processing capacity and efficiency of the entire crushing line.
Our Vibrating Grizzly Feeder effectively combines feeding and scalping in one solution. It is designed to deliver material to a crusher in a primary application, most commonly in mining and mineral processing. Such applications can also be found in aggregates, concrete & recycling industries. Our Vibrating Grizzly handles high-impact loads and operates at high g-forces in order to produce efficient separation of lump and fine ore with the linear motion being produced by exciter units mounted below the grizzly. The fine ore passes through the tapered grizzly fingers and bypasses the crusher, whereby the lumps are fed into the primary crusher. The process will maximize the overall crushing plant capacity and reduce the wear within the crusher.
