Mill (grinding)

Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore,

Ball Charge and Grinding Efficiency Grinding

Ball Charge and Grinding Efficiency (22 replies) Ball size will also affect the grind P80. Efficiency is in part determined by the Axb value of the ore. A small lab mill can give guidance on the influence of ore strength and ball size. Larger balls will increase P80 in ball mill, thereby reducing overgrinding.
