Apr 09, 2015· Product size can be as small as 0.005 mm, but product size is dependent upon the time the charge spends in the grinding zone and therefore the reduction rate is a function of the throughput. The speed of rotation is optimum at about 75 % of critical speed. Some mills are compartmentalized with each subsequent section having a smaller ball size.

Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Inside a ball mill, the balls move round in a circle as the mill turns, crushing the ore into a powder. This process of reducing the size of the rocks requires a lot of energy. Just image how hard it is to break a rock. How much more energy do you think is needed to crush a rock until it is like sand?
