WM4500 Industrial Sawmill

Robust, High-Performance Industrial Sawmill

 

Thin-Kerf Blade Technology

Put the robust, high-performance WM4500 to work as a primary industrial sawmill to saw boards, grade, and dimensional lumber or integrate it into a larger operation to break down logs for further processing. Capitalizing on thin-kerf blade technology, the WM4500 produces accurate lumber while reducing capital, material, labor, energy, and maintenance costs without compromising production.

Key innovations of the WM4500 sawmill bed include stronger angled bed rails, reinforced dual-rod side supports, adjustable material drag back, off-feed conveyor & roller with suspension, pull down cinch clamps, modular toeboards, and a longer cutting length up to 6.85 m. The more robust sawmill head is equipped with 51 mm blades, balanced steel band wheels, 76 mm diameter blade guide rollers, 50% stronger head structure and vertical tube and an enhanced strain system with a higher capacity air bag.

Honey Grove Hardwoods improved efficiency, yield, and profits by replacing their circular sawmill with a WM4000 headrig. Read Their Story

The WM4000 is ideal to:

  • Launch a startup sawmill operation.

  • Add to a circle mill operation to get the most profit out of high-grade and irregular logs.

  • Add to a thin kerf operation to boost productivity with a smaller initial investment.

  • Add to a WM3500 operation to more than double production capabilities.

  • Replace an expanding portable sawmill operation to meet increasing production requirements.
