Patterson Industries - Continuous-Type Ball & .

Open Circuit Operations Continuous open circuit operation is smooth, simple and positive. Material passes steadily through the open feed trunnion of the mill. It is then ground to desired fineness and discharged at the opposite end. Closed Circuit Systems Continuous Mills are used in closed circuit operations for maximum control of product size, economical grinding and low contamination ...

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 that is ground from the mill in to coarse and fine ...

Grinding Circuit - an overview | ScienceDirect Topics

Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.

Definition of closed-circuit grinding - Mindat

Definition of closed-circuit grinding. A size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit. Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill with a classifier. See Also: circulating load.
