BM&M 4X10 Gyratory 2 Screen Screener

The BM&M 4×10 Gyratory 2-Deck Screener is a high-capacity industrial separation and particle sizing machine featuring a 4-foot wide by 10-foot long deck area per level.

Key Specifications & Design
• Decks: 2 decks (40 sq. ft. of screening area per deck).
• Operating Speed: Approximately 300 RPM (with a standard 2-inch diameter stroke).
• Screen Slope: Typically 3° to 7°.
• Drive Technology: Centralized static shaft drive located at the absolute center of the machine, producing a uniform gyratory/orbital motion across the entire screen surface.
• Suspension: Rigid four-hanger arm assembly that isolates dynamic balancing forces and minimizes structural/building vibration.

Main Features & Benefits
• Deblinding Efficiency: Equipped with ball decks beneath the screen mesh where bouncing synthetic balls dislodge near-sized particles or fines to prevent blinding.
• Screen Tensioning System: Keeps screen wire taut across the surface for higher screening consistency and easy element slide-out via hinged access doors.
• Applications: Widely used for wood chips, bark, sawdust, recycling materials, and general bulk material sizing or scalping.
