Get PriceMost modern mills have variable-speed drives, and are considered low-energy mills when operated at low speeds (i.e., <1000 rpm). Such mills produce granulation within this desired particle-size range and are commonly used within the pharmaceutical industry for granulation-size reduction.
Get PriceThe ball mill usually contains differing sizes and diameters of balls. It can also have wet or dry designs. Ball mills actually reduce the size of pharmaceutical agents through impact and attrition. Initially, the active ingredients are flattened by the colliding balls. The ball mill is an effective tool in grinding delicate, brittle and sticky ...
