Ball Mill Bearing Problems. On the 116quot × 220quot ball mill, the bearing lubrication problem of the ball mill is that the trunnion bearing lubrication system provides continuous low-pressure overflow oil for the cooling and lubrication of the bearing, and provides high-pressure oil for the hydrostatic lifting of the feed and discharge trunnions during the start-up of the mill

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in
