In contrast, mills closed by fine screens are limited to using only the most competent media. the power efficiency of coarse isamilling with ceramic media is much higher than for conventional ball or tower milling.

Grinding Control Strategy On The Conventional Milling :

to the second milling circuit that runs in closed circuit with its own cyclone ball mill discharges to a sump where water is added before the slurry is pumped to cyclone cyclone overflow gravitates to a distributor and is combined with cyclone overflow before gravitating to the flotation circuit. cyclone underflow In an open circuit system, the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system, coarse particles are separated from the finer product and returned for a further grinding. In a closed circuit mill, the total throughput is higher and hence the size of material from closed circuit ball mill system clinker, gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams coarse and fines.closed-circuit or open-circuit. ball mills may operate in a closed-circuit, or open-circuit. closed circuits return a certain amount of the ball mills output back to the ball mill for further size reduction. typical closed system grinds the ore between two to three times.
