An Attritor Mill, also known as a Stirred Ball Mill or Agitated Media Mill, is a high-energy milling machine designed for ultra-fine grinding, blending, and particle size reduction. It operates by vigorously agitating a bed of grinding media (typically balls or beads) inside a stationary, vertical chamber using a rotating shaft with arms or impellers.
Attritor mills are ideal for wet or dry grinding and are extensively used in industries where fine dispersion, high-energy milling, and narrow particle size distribution are critical.
