A typical salad bowl is about 3040 cm wide, whereas the LHC has a diameter of km. The LHC's huge size is one of the reasons why it can accelerate particles almost to the speed of light. In the salad bowl accelerator, the speed of the ball is limited by friction and by the rate of charge transfer between the strip and the ball.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

The third step in crushing, or tertiary reduction, depends upon what is required. Twoinch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½ or 5/8in. size before wet crushing, particularly in the case of ball milling.

2. History of development and different mill designs Originally, tumbling ball mills were often used for wet fine and ultrafine grinding. But since the power consumption of tumbling ball mills is limited by the number of revolutions at which the grinding media are centrifugated at the chamber wall, the power density is relatively small.

The prepared PBG was milled using a small horizontal ball mill. Two kilograms of the material were loaded into the ball mill each time. The ratio of PBG to balls was 1 : 1, and the samples were then grouped according to the duration of the ball milling process (10, 20, 30, 40, 50, 60, and 70 min), as shown in Table 2.
