22 may, 2019. the ball mill consists ofetal cylinder andall. 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. atertain height, it will automatically fall and impact and grind the material.
22. for effective operation of ball mill the ball charge volume of mill filled by the balls should be07005000. 23. critical speed of the ball mill is the speed at whichalls begin to centrifuge with the millalls cascade over one anotheralls are carried up the sides and fall freely onto.

A ball mill also known as pebble mill or tumbling mill isilling machine that consists ofallow cylinder containing balls mounted onetallic 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.
A ball mill is one kind of grinding machine, and it isevice in which media balls and solid materials the materials to be ground are placed inontainer. the materials are ground by moving the container. because the structure of ball mills is simple and it is easy to operate, and so they are widely used.
A ball mill,ype of grinder, isylindrical device used in grinding or mixing materials like ores, chemicals, ceramic raw materials and paints. ball mills rotate aroundorizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls,flint pebbles.
