1. Low speed, large transmission torque, low noise, less dust generation and simple operation. 2. It adopts new claw-type cutter and adjustable-free movable blade design. After re-grinding the movable blade, the gap is adjusted to maintain a fixed cutting gap. 3. Slow rotation, the design of sharp-angle moving knife helps the mill to operate more smoothly . 4.The design of the surrounding of the crushing chamber of the aggregate box can effectively prevent the leakage of crushed materials during crushing. 5. Shear angle, small resistance, not easy to jam, improve cutting efficiency
