    Sep 15 2011 · 1. Introduction. Due to their high energy density planetary ball mills are especially suited for fine and ultra-fine grinding of hard and brittle material down to the nanometre size range for mechanical alloying and for mechanochemical reactions (among others ) comparison to ball mills and vibrating mills higher stress intensities can be generated due to the centrifugal field. Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.

    When the ball mill works stably the amount of material entering the ball mill is basically equal to the amount of material discharged from the ball mill. But sometimes some reasons (such as the amount of returning sand increase the amount of raw ore increase) will lead to the amount of material fed into the ball mill increased which beyond the maximum capacity that ball mill allows so In the present case study the causes of the high vibrations on a double-drive cement mill is investigated by performing a series of vibration measurements on the cement mill pinion and the main
