a ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. the balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size..ball mill operation -grinding circuit startup & shutdown,normal shutdown sequence of ball mill and grinding circuit . shut off cyanide metering pump. put weight controller into manual mode and turn controller output to 0%. run the ball mill for 15-30 minutes. put density controller into manual mode, set output to 0%. put flow controller into manual mode and set output to 0%. turn off ball mill lime timer..ball mill maintenance & installation procedure,how to start a ball mill or rod mill start the lubrication system and run it for about ten minutes, adjusting the oil flow at each bearing. check all of the bolts and nuts on the mill for tightness and remove all ladders, tools and other obstructions prior to starting the mill..ball mill - an overview,oleg d. neikov, in handbook of non-ferrous metal powders, 2009 tumbling ball mills. tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. grinding elements in ball mills travel at different velocities. therefore, collision force, direction and kinetic energy between two or more elements vary
