About

With over 70 years under our belt, we're not the new kids on the block.

WSM started in Pacific Northwest sawmill operations. Rainfall exceeds 120" per year – trees and mills grow big here. We served them.

We entered the recycling industry before anyone knew what it was. As our reputation spread, other industries wanted WSM's unique combination of mill-duty machines and systems that delivered reliable operation. We responded to their needs.

WSM brings customers an over 70 year reputation for performance, durability, and reliability – and we’re just getting started.

WSM is your source for trommel screens, disc screens, hogs, grinders, hammermills, pellet processing, chippers, and shredders.
