ZJH mainly focus on producing and supply laboratory and pilot scale type of ore dressing equipment for Mining and Mineral Processing Industry.Our aim is to work together with Mines, Mineral Beneficiation Plants for helping to reduce the operating cost,to improve the operating efficiency.
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 …
mill is the limiting factor for long-term, permanent installations, as it is a high-wear, high maintenance machine. A ball mill is a logical and more permanent upgrade that can be installed later, to replace the hammer mill. With a ball mill, the turn-key ore processor is suited to run for 10,000s of tons with only routine maintenance.

For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
