Ore Ball Mill Closed Circuit Introduction
A two-stage grinding circuit using a rod mill in a a two-stage grinding circuit using a rod mill in an open circuit with a ball mill in a closed circuit with a cyclone classifier is used to grind 100 tonnes per hour of ore s.g. = 3 . the circuit layout is illustrated in the figure below. assuming that the circuit.Apr 01, 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 produce the desired final.
