ball mill

Abstract

The invention discloses a ball grinding mill. The ball grinding mill comprises a fixed frame, an outer cylinder body, an inner cylinder body internally arranged in the outer cylinder body, a rotating shaft and a motor; a grinding cavity is formed in the inner cylinder body, the rotating shaft comprises a left rotating shaft body and a right rotating shaft body which are coaxially arranged, one end of the left rotating shaft body and one end of the right rotating shaft body are connected with the fixed frame, and the other end of the left rotating shaft body and the other end of the right rotating shaft body penetrate the outer cylinder body and are connected with the inner cylinder body; the motor drives the rotating shaft to rotate; the rotating shaft and the outer cylinder body are coaxially arranged, and the central axis of the inner cylinder body and the central axis of the outer cylinder body are intersected and form an included angle; and the inner cylinder body is arranged, an included angle is formed between the central axis of the grinding cavity of the inner cylinder body and the rotating axis of the inner cylinder body, materials in the inner cylinder body more easily roll over along rotation of the inner cylinder body, sufficient mixing of the materials is facilitated, collision grinding of a grinding body, the materials and the inner wall of the inner cylinder body is facilitated, and grinding uniformity and the grinding efficiency of the grinding mill are both higher.

Description

technical field [0001] The invention relates to grinding technology, in particular to a ball mill. Background technique [0002] The ball mill is mainly used for grinding materials. The existing ball mill mainly grinds the material into powder through a horizontal cylinder and a grinding body arranged in the cylinder. The grinding body rolls in the cylinder and collides with the material. However, when the material in the cylinder exceeds the height of the central axis of the cylinder, the grinding effect of the material is poor and the grinding uniformity is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and propose a ball mill to solve the technical problems of poor grinding effect and low uniformity of the ball mill in the prior art. [0004] In order to achieve the above technical purpose, the technical solution of the present invention provides a ball mill, comprising: [0005] a...
