electric control circuits for ball mill for iron ore

  • Supervisory expert control for ball mill grinding circuits

    01/04/2008· Ball mill grinding circuits are important unit operations in the production of metals from ore. The function of the grinding mill is to reduce the particle size of the ore such that the valuable mineral constituent is exposed and can be recovered in the subsequent flotation operation.

  • A guide to maximising ball mill circuit classification

    G = ore grindability (grams per revolution) MGeff = Mill Grinding Efficiency [(metric tonnes per kWh) / (g/rev)] The equation components are measured by means of a ball mill circuit survey and a laboratory test of the ore grindability. As can be seen in the equation, the mill power (kW) being used ‘effectively’ (on coarse particles) is simply the product of the mill power and the CSE

    Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators.

    circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to

  • Grinding Circuit an overview ScienceDirect Topics

    To liberate minerals from sparsely distributed and depleting the ore bodies finer grinding than generally obtained by the conventional Rod Mill –Ball Mill grinding circuits is needed. Longer grinding periods in the conventional milling processes prove too expensive mainly due to large power consumption. Stirrer mills have been tried in mineral industry with considerable success and have
