The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer ...

Media Milling, Dry and Wet. Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high or lowenergy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.

Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
