BM&M 4' x 10' Two-Deck Chip Screen

High-Speed Chip Classification • Two Separation Decks • Ideal for Sawmill & Biomass Applications

The BM&M 4' x 10' two-deck chip screen is a compact, high-efficiency chip classifier widely used in sawmills, panel plants, pellet mills, and biomass facilities. Known for its unique balanced gyratory screening motion, BM&M screens deliver exceptional chip separation with minimal vibration transmitted to the structure, allowing installation in tighter spaces or lighter screening towers than traditional shaker screens.

This two-deck 4x10 unit provides precise chip sizing, separating overs, accepts, and fines to meet pulp, pellet, or fuel-chip specifications. BM&M’s simple drive system, long-life suspension mounts, and fast screen panel changeout make their screens some of the most maintenance-friendly in the industry.
