The ROM SAG mill circuit—a brief description The typical ROM SAG mill circuit is depicted in Figure 1. The circuit is usually closed with either a screen or, more commonly, a cyclone for product size classification. The focus of control can be divided into two parts, viz. the mill and the cyclone. The importance of cyclone performance should ...

Maximising grinding mill efficiency with ... - Instrumentation
For SAG and AG mills there is an inverse parabolic relationship between mill power and mill load as shown in Figure 3. Thus maximum grinding efficiency, and therefore maximum production rate, occurs at the point of maximum power on the power/load relationship.

A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce ...
