Ball mill - Wikipedia

2018-12-21 · Critical speed can be understood as that speed after which the steel balls (which are responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines
