The sample was crushed 100 to 6 mm.All operating variables were measured under controlled conditions to produce a mass balance of the test.A laboratory batch ball mill was used to characterize the sample in order to determine the energy specific selection function and the breakage function.
READ MOREStockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn.When the load becomes critically high, the feed needs to be cut in order to grind the mill out.This dramatic change in mass flow and particle size is passed to the downstream processes, causing.
READ MOREChromite rich fraction through the ball mill.This circuit is typical of a ug2 plant in which maximum silicate with minimal chromite breakage is targeted.As a result of the circuit change an opportunity for optimisation around the industrial scale ball mill was considered for this study.
READ MOREIt is commonly referred to as a sabc circuit, for semi-autogenous ball mill crusher sabc.This circuit shows a semi-autogenous grinding sagball mill circuit where both grinding mills are in closed circuit, with the sag mill closed with a crusher to control the amount of critical size material in the circuit.
READ MOREThe tool to identify energy losses in a wet grinding circuit was delivered to cmic.Despite the complexity of the processes and the difficulty in measuring slurry temperatures, it is relatively easy to determine a circuits detailed energy balance.Data from the three grinding circuits studied show that on average 77 of the electrical energy.
