Three common shapes of the grinding medium

The shape of the grinding medium can be divided into spherical shape, rod shape, short cylindrical shape, frustum shape as well as some other forms. Due to different shapes, the principles are different, which provides possibility for the selective grinding. At present, the common shapes of grinding medium are as follows. 1. Sphere.
