Impact mils are high-speed "beater mills" used for pulverising and micro-pulverising dry materials. In addition to (micro) pulverisation in the < 100 µm range, the Impact Mill has proven to be very reliable and efficient in defibrating organic substances (paper, paperboard, cellulose, etc.), grinding-coating, cryogenic grinding, combined grinding/blending and grinding/drying.
