ball mill for grinding system

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.

The High Energy Ball Mill Emax combines high-frequency impact, intensive friction, and controlled circular jar movements to a unique and highly effective size reduction mechanism. The grinding jars have an oval shape and are mounted on two discs respectively which move the jars on a circular course without changing their orientation.

Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials.

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 occurs during impact falling grinding balls and abrasion the particles between the balls.

Your mill liner has a critical role to play in the performance of your ball mill – which is why you need a liner that is perfectly designed for your grinding application. Whether you need step and wave liners that optimise your coarse grinding operation or corrugated
