Chat OnlineA 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 axishe balls which could be of different diameter occupy 30 -50 of the mill volume and its size depends on the feed and mill size.
Chat Online2012-11-26the critical speed is used for the determination of ball mill ideal operating speedut for comparison, rod mills would operate between 50 to 95 of the critical speedhe faster the mill speed, the greater the wear on the rods and linerso, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the.
Chat OnlineBall mill critical speed mineral processing metallurgy ball mill critical speed actually ball, rod, ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell.

Chat OnlineBall mills are usually operated at 75 of the critical speedhe critical speed is the speed where, mathematically calculated, the grinding media would centrifuge outills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2ms mill of this size equipped with.
Chat OnlineBall mill critical speed transsporthe critical speed of ball mill is given by, where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm, n c 307 rpm but the mill is operated at a speed of 15 rpm therefore, the mill is operated at 100 x 15307 4886 of critical speed.
Chat OnlineA ball mill grinds material by rotating a cylinder with steel or ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be groundll mills have been successfully run at speeds between 60 and 90 percent of critical speedwever, most ball mills operate at speeds between 65 and 75 percent of critical speed.
Chat OnlineThe common range of mill speeds is 65 to 80 of critical, depending on mill type, size and the appliionhe critical speed of a ball mill is calculated as 54 divided by the square root of the radius in feethe rotational speed is defined as a percentage of the critical speedmaller diameter mills.
