Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill which is convenient for feeding and discharging materials. Background Art

[0002] A ball mill is a common grinding equipment, which is widely used in various industrial fields, such as mineral processing, ceramics, cement, refractory materials, etc. It uses the rotation and impact of the balls inside the ball mill to break and grind the materials inside the ball mill into fine powder. There are many types of ball mills on the market, mainly including horizontal and vertical types. A feed port is generally set at the end of the ball mill to facilitate the feeding and adding operation. In addition, a discharge port is set on the cylinder of the ball mill to facilitate the discharge operation.

[0003] However, when the ball mills on the market are used, the feed port is generally arranged horizontally, and the inner diameter of the feed port is relatively small, which makes feeding inconvenient. In addition, the discharge port is generally fixed on the ball mill with a plate body and fastening bolts. Although multiple fastening bolts can achieve a stable fixation effect, it is not portable to unscrew the fastening bolts for disassembly each time, which brings inconvenience to users. In view of this, we propose a ball mill that is easy to feed and discharge. Utility Model Content
