BM&M 12 x 20 Chip Screen

BM&M 12' x 20' Two-Deck Wood Chip Screen

BM&M is widely recognized as the industry leader in wood chip screening, and this 12' x 20' two-deck screen is a proven, high-capacity unit designed for demanding mill applications.

This machine is configured for three-way separation, producing overs, accepts, and fines in a single pass—ideal for pulp mills, biomass operations, and chip processing systems where consistent chip quality is critical.

The screen utilizes BM&M’s gyratory screening motion, providing aggressive, uniform material movement across the full deck surface. The result is high efficiency, excellent separation accuracy, and strong throughput compared to conventional vibrating screens.

Key Features:

• Two-deck design for three separations (overs / accepts / fines)
• Large 12' x 20' screening area for high capacity applications
• Single-bearing drive mechanism for smooth operation and reduced maintenance
• Suspended design with heavy-duty hanger arms and U-joints, isolating vibration and extending structural life
• Balanced gyratory motion for consistent screening across the entire deck
• Heavy-duty construction built for continuous mill service

Capacity:

Depending on chip size distribution and screening requirements, units of this size typically handle in the range of 150–300+ tons per hour of wood chips, making them suitable for medium to large-scale operations.

BM&M screens are known for maximizing recovery of acceptable chips while efficiently removing oversize and fines, helping improve downstream performance and overall mill efficiency.

This unit presently configured with heavy duty woven screens at both levels.
