May 22 2019 · 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 forceFurther Details
in the ball mill takes place by impact fr iction and abra sion betwe en rocks a nd balls inside the mill during rotation 1 2Steel balls are charged int o a cylinder along with the materialFurther Details
THEORY The ball mill is classified as an intermediate and fine grinder where the action of the grinding is based on impact and attrition The ball mill consists of a cylindrical shell slowly turning about a horizontal axis and filled to about half its volume with a solid grinding mediumFurther Details
Dec 24 2013 · The first factor is the speed of rotation while operating the ball mill At high angular velocities the balls are thrown onto the mill wall by centrifugal force and no size reduction occurs At low angular velocities the balls move with drum until the gravity force exceeds the frictional force of the bed on the drum then it will slide back to the base of the drumFurther Details
The proper operating speed of a ballmill increases as the size of the ball load increases Due to interference between the balls the volume of the charge should not be over 60 per cent of the volume of the millFurther Details
