    Multi-Screen Series Rotary Brush

    Rotary brush system for multi-screen separators consists of a brush system and mobile chassis. Rotary brush operates independently to the separator at low rpm. Lumps are broken apart by horizontal scraping motions and vertical crushing motions between the brush and screen. Particles too large to pass through are brushed aside to prevent clogging of the screen, improving efficiency and productivity of easily clustered material.
