produced by the ball mill, so the cyclone overflow allows a lot of these middle size particles to escape the grinding circuit. this results in a decrease of material that the ball mill would have to grind, which lowers its efficiency. also, unwanted particle sizes are leaving the grinding circuit to next process stages.background OF the invention In the present state of the art there are few ball mill grinding devices that have any type of load control. regulation of the rate of feed of new material to a grinding mill circuit has been tried, whether the grinding mill circuit is arranged in a normal or a reversed circuit arrangmeent, at a substantially constant rate.
one stage grading process with checking grading operation is the most widely used. the ore is directly fed into the grinding machine, and the optimum particle size for the ore is generally mm. particle checking classifier separates the ground material into qualified products and unqualified products, the unqualified materials are sent back to grinding mill.the ball mill will be equipped with a single 4,200 kW wound rotor induction motor, trommel screen and retractable feed spoutchute. the combined mills discharge slurry will be pumped to the mill cyclone cluster operating in closed circuit configuration with the ball mill.
