#### Closed circuit ball mill Basics revisited ScienceDirect

2013-4-1 · It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. This is because of the reduction in classification efficiency from 50% to 30% as calculated by Eq. (11).

#### Grinding control strategy on the conventional milling

2009-8-27 · Water addition at Cyclone 1 is used to control particle sizeof the overflow stream of this circuit. In essence this onlydetermines the mass cut to overflow and underflow. With afiner particle size in the overflow, there is thus less materialin the overflow. This implies more material in the under-flow, which is the fresh feed to the second ball mill. If circulating load in the second ball mill is kept constant,any variation in the fresh feed will ultimately be reflected inthe product particle size of Cyclone 2. Water addition toCyclone 1 feed sump therefore not only controls the Cyclone 1product particle size, but ultimately also Cyclone
