A ball mill for use in mechanical alloying and grinding comprising a plurality of ferromagnetic balls within a spherical or cylindrical chamber or cell of a paramagnetic material. The chamber has a substantially horizontal axis of rotation. At least one magnet is mounted outside the chamber to produce a magnetic field within the chamber.

Wet Grid Ball Mill Crushing Screening Conveying

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.
