Abstract
The invention relates to a grinding device which comprises a grinding cylinder, a grinding mechanism and a material separation mechanism. The grinding mechanism comprises a grinding scattering wheel which comprises a grinding wheel body with a center through hole. Axial holes distributed in the periphery of the center through hole are evenly distributed in the two sides of the grinding wheel body. The axial holes are communicated with radial blind holes evenly distributed in the grinding wheel body in the radial direction to form an axial channel. A radial channel formed by the radial through holes of the outer side and the inner side in the radial direction is arranged between the adjacent radial blind holes. As the axial channel formed by the axial holes and the radial blind holes and the radial channels which are distributed at intervals are arranged on the grinding wheel body, and grinding balls and grinding materials form axial circulation on the axial channel of the grinding wheel body and form radial circulation on the radial channels of the grinding wheel body. The grinding balls move in the tangential direction and at the same time, has the rotational velocity, so that tangential torque is generated between the grinding balls and the probability of capturing the ground materials is improved. Thus, materials are prevented from being re-aggregated after being ground for a long time and thus, the grinding efficiency is improved.
