West Salem Custom Grinders & Hogs

WSM horizontal feed grinders offer a comprehensive solution for your industrial grinding and processing needs

Full range of sizes available to process from 1 to 150 tons per hour. WSM horizontal grinder systems deliver superior processing performance while minimizing maintenance and horsepower requirements.

The horizontal feed design allows for easy handling of long and bulky piece size material.  Material is loaded on the infeed conveyor to WSM's revolutionary powered feel roll which provides a metered, controlled feed to the grinder.  Automatic load sensing maximizes thru-put and improves the handling of surge conditions.

Powered Infeed Mechanism is a key component in the horizontal grinding system, consisting of a pivoting steel frame around a powered feedroll mechanism. The frame adjusts using hydraulic cylinders maintaining positive downward pressure, while the feedroll aggressively grips the material to provide a positive, consistent, and controlled flow of material to the grinder.

Hammer pins constructed from high strength alloy steel, with ends drilled and tapped for easier removal

Rotor assembly constructed with heavy-duty machined shaft, rotor discs, and alloy steel hammer pins

Abrasion-resistant steel screen bars or perforated plates produce a finished product in a single pass. Available in a full range of sizes, screens are modular and interchangeable for extended wear life.

Removable bearing support blocks allow for bearing removal without lifting rotor assembly

Heavy-duty double row spherical roller bearings and pillow block bearing housings provide superior bearing life

The optional pivoting split front housing on larger units with dual hydraulic cylinders mounted on the sides of the machine provides for easy routine inspections and maintenance making the grinder faster, simpler, and safer to open.

Heavy-duty fabricated steel housing with massive frame doors for superior strength and wear life. Extra-heavy interior AR steel wear liners for extended machine life.

Rotor shaft end is drilled and rifled on each end for hydraulic bearing removal
