Production. Copper. This long row of large capacity ball mills is used for fine grinding of copper ore at one of the concentrators of the Utah Copper Company. Its mills at Magna and Arthur in Utah are treating vast quantities of the copper so vital for war purposes. United States Salt Lake County Utah, None.
Based on the results, low (30 minute) or high (50 minute) grinding time reduces fractal dimension and recovery because low grinding time is resulted in a coarse grain product while high grinding ...
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
