In open circuit grinding, passage of material is only once through the mill. Consequently, a consistent product fineness is difficult to achieve. Installations having a hydraulic roll press prior to mills are common. In closed circuit grinding, a high efficiency separator (O-Sepa or Sepax, Sepol) is in operation which separates the material

The operation is classified as fine grinding if the bulk of the product passes a 200-mesh screen (7.6 x 10-5 m) or as superfine grinding if a powder of a few microns or less is required. Most pharmaceutical grinding falls into these classes, although coarser grinding is applied to vegetable drugs before extraction.
