A variant of the rotating or tumbling ball mill is the planetary ball mill This variant imparts a higher degree of energy in an attempt to create finer or more homogeneous powder size distributions Instead of relying on gravity to accelerate the balls the mill chamber is placed offcenter on a rotating platform
Chat OnlineMotion of Balls through the Porous Bed The transport of slurry through the ballbed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill When balls of different sizes are present in the mill then there is a tendency for the balls
More DetailsThe following article describes types of ball mill affecting factors ball mill grinding media and working principle The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated “ball mills”
More DetailsWhen the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length New feed entering at one end of the mill causes the rod charge to spread at that end This produces a series of wedge shaped slots tapering toward the discharge end The tumbling and rolling rods expend most of their crushing force on the
More DetailsBall Mill Operation Ball mills ride on steel tires or supported on both ends by trunnions Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive The prime movers are usually synchronized motors During rotation a portion of the charge is lifted along the inside perimeter
More DetailsA 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
