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..basic operation of a ball mill | prominer (shanghai,basic operation of a ball mill. basic operation of a ball mill-ball mill. cement ball mill basic operation principles the operating principle of the ball mill consists of following steps in a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media the material grinding . get price.construction of ball mill/ ball mill structure | henan,ball mill introduction. structurally, each ball mill consists of a horizontal cylindrical shell, provided with renewable wearing liners and a charge of grinding medium. the drum is supported so as to rotate on its axis on hollow trunnions attached to the end walls (attached figure 1 ball mill)..amit 135: lesson 7 ball mills & circuits – mining mill,ball 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.
mechanisms of grinding in a ball mill can be broadly grouped as either impact or attrition with at least two forms of breakage attributable to each type. impact breakage may occur as a result of a particle being smashed between balls or between a ball and the mill lining, but is also generally defined to include slow compression fracturing, or crushing of particles between grinding media..the operating speed of a ball mill should be the critical,the operating speed of a ball mill should be __________ the critical speed. a. less than. b. much more than. c. at least equal to. d. slightly more than. answer: option a..the working principle of ball mill - meetyou carbide,the ball mill consists of a metal cylinder and a ball. the working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force..operation of a ball mill of gold- exodus mining machine,for efficient operation of ball mills necessary to observe the right balance between balls size and feed material size if the feed material contains many large lumps and grinding balls cant crush them it leads to a gradual accumulation them between the balls as a result mill suspends own operation. more details
