XY Heavy Duty Grizzly Feeder for Efficient Pre-screening and Uniform Feeding

In mining and aggregate processing, excessive clay and moisture in raw materials often become a major bottleneck for coarse crushing efficiency. Addressing this critical challenge, Sichuan Xinyida Machinery has developed the XY Heavy-duty Grizzly Feeder – a robust feeding solution that combines advanced vibration technology with a specially engineered three-stage grizzly design to deliver superior pre-screening performance and enhance overall production line productivity.

Core Advantages: Three-Stage Pre-screening & Variable Frequency Control

The feeder's standout feature is its unique three-stage grizzly structure, which effectively prevents material blockages while efficiently stripping and removing mud, fines, and small-sized gravel from the feed stream. This "pre-splitting" capability ensures that only clean, properly sized material enters the primary crusher, significantly reducing wear on crushing components and boosting coarse crushing capacity. Equipped with a variable frequency speed-regulating motor, the unit allows operators to easily and precisely adjust feeding rates, ensuring uniform, stable material flow. This results in smoother start-ups, simplified control, and optimized performance across the entire production line.

Engineered for Durability and Reliability

Built with a heavy-duty shaft-and-block eccentric excitation system, the XY Feeder delivers powerful vibration force while withstanding the impact of falling large materials. Its side plates are fabricated from high-yield strength steel with reinforced exciter areas, and the screen body utilizes Huck rivets and a hemming process – eliminating weld-induced stress concentration and preventing frame loosening or deformation under prolonged operation. This design grants exceptional fatigue strength and long-term durability.

Advanced Manufacturing & Maintenance-Friendly Design

Manufactured with precision on gantry boring and milling machines, the feeder ensures perfect alignment and concentricity for the exciter assembly. Bearing housings are cast from special alloy steel to resist wear and prevent outer race rotation, drastically reducing replacement frequency. An advanced thin-oil lubrication system, combined with a labyrinth seal to prevent leakage, delivers superior cooling and lower operating costs while more than doubling bearing service life.

With its proven performance, rugged construction, and customizable configurations, the XY Heavy-duty Grizzly Feeder is the trusted choice for improving feeding efficiency and maximizing crushing plant output.
