Description

Technical Field

[0001] This utility model relates to the technical field of barite processing equipment, and in particular to a structure for barite powder grinding. Background Technology

[0002] Barite is the most common barium mineral, composed of barium sulfate. It is an important non-metallic mineral raw material with wide industrial applications. In actual production, large pieces of barite need to be ground into powder before use, requiring initial crushing during the grinding process. Existing barite crushing equipment suffers from the problem of easily ejected fragments during operation. This not only impacts the surrounding working environment but, more seriously, poses a threat to the personal safety of operators. If high-speed fragments strike workers, they could be injured, leading to accidents. Currently, there is an urgent need in the market for a barite grinding structure that can effectively prevent fragment ejection and ensure worker safety. Utility Model Content

The upper end of the feeding pipe 502 is fixedly connected to the lower part of the grinding box 501. The upper end of the transmission shaft 504 passes through the side wall of the feeding pipe 502 and is fixedly connected to the middle part of the grinding shaft 506. The outer periphery of the grinding shaft 506 is arranged in the middle part of the grinding block 505. The outer periphery of the grinding block 505 is fixedly connected to the lower part of the inner side of the grinding box 501.
