1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to .

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 in the product particle size of Cyclone 2. Water addition to Cyclone 1 feed sump therefore not only controls the Cyclone 1

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in .

CONCLUSION The circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and HPGR circuits. This is a well-known fact for ball mill circuits that has been recognised for almost 100 years. For HPGR circuits the knowledge is more recent, and is still being investigated.
