Is a horizontal grinder right for your site? As a leader in screening and size reduction machinery, WSM has the right solutions for your industrial grinding and processing needs. 

West Salem Machinery produces rugged and reliable grinding, screening, and conveying equipment as individual components or as the core of a customized, fully engineered package. With the most extensive product line available, we deliver customized and integrated solutions for a wide range of needs.


West Salem offers a line of horizontal grinders in a full range of sizes that can process from one to 150 tons per hour.

West Salem’s horizontal grinders and horizontal wood hogs offer superior processing performance, while minimizing the need for maintenance and additional horsepower. 


WSM’s industrial grinders are designed with maintenance friendly design features to save you time, money, and headaches. Businesses reduce their maintenance budgets with features like a front section that pivots down for a maintenance working surface. The pivoting hog case assembly can be open while the infeed system remains in place. 

Belt conveyors include a “speed-up” roll for extended wear life. Large grinding systems use our multi-strand chain conveyor for direct loading of batch loads and has reversing capabilities. 


We get the best results by using the unbeatable combination of field/application experience, in-house testing, and innovative design staff – learning fast and applying what we learn – to correctly design, size, and improve our machines and systems to ensure successful installations.

Design features include:

  • Heavy duty fabricated steel housing for superior strength and wear life
  • Abrasion-resistant steel screen bars or perforated plates produce a finished product in a single pass
  • Inspection ports and rear access doors allow access to upper and lower housing
  • Rear access doors allow for a “quick check” of the machine with case still in place.
  • Heavy-duty double row spherical roller bearing and pillow block bearing housings for superior bearing life
  • Interior housing lined with 1”-3” thick bolt-in AR wear liners for long machine life
  • Massive hammer bodies with reversible, rebuildable tips available
  • Easy to handle modular grate screens make for easier maintenance, cost savings, and consistent product size
