nov 26, 2019 and because the ball mill feed grain size is larger, ball mill feeding groove must have a larger slope and height, so that feed smooth. bearing. since the power of the autogenous tumbling mill is relatively small, it is appropriate to choose dynamic and static pressure bearing. the ball bearing liner is made of lead-based bearing alloy, and the
ball mills are also used for the particle size reduction of black powder, cement, fertilizer, silicates and even a variety of ferrous and non-ferrous metals. ball mills are very similar in design and operating concept to rock tumblers, which used milling media to polish rocks in a rotating cylinder.
the interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill. across international gear-drive 4-station planetary ball mills have built-in, reverse and timing functions. high energy ball mills grind down material to sub-micron level in minutes.
the mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

the design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material and the system for discharging the output product. the size of a mill is usually characterized by the ratio length to diameter and this ratio most frequently varies from 0.5 to 3.5. the
investigations were carried out in a laboratory ball mill having the size of dxl 200 mm with a ribbed inside surface of the drum. the mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. balls were made from steel: extra high quality, having hardness 62 hrc according to rockwell.
ball mills are generally used to grind material 14 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.
