Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a feeding structure of a ball mill. Background Art

[0002] A ball mill is a commonly used grinding or grinding equipment. Its working principle is that when the cylinder rotates, the spherical grinding body is lifted up due to the friction of the inner wall of the cylinder. When its rising angle exceeds the repose angle, the grinding body falls downward, and the material is crushed by the impact of the falling grinding body and the grinding action between the grinding body and the inner wall of the cylinder. It can be mainly used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, glass and ceramics and other production industries. However, during the use of the current ball mill, since the shapes and sizes of the materials to be crushed by the ball mill are different, the feed port of the ball mill will be blocked, which will cause interruption of feeding. Therefore, we propose a feeding structure of a ball mill to solve the above problem. Utility Model Content
