Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a dust reduction chute at a ball mill feed port. Background Art

[0002] Ball mills are key equipment for pulverizing materials after crushing. They are widely used in industries such as cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics, performing dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding a variety of ores and other materials, and are widely used in industries such as mineral processing, building materials, and chemicals. They can be divided into two types of grinding methods: dry and wet.

[0003] The prior art describes a dust reduction chute for a ball mill feed inlet. It comprises a receiving chamber with a square cross-section, the lower end of which communicates with one end of a transition chamber with a square cross-section. The other end of the transition chamber is connected to a square port of a square-round pipe, which in turn is connected to a circular feed pipe. A baffle is mounted on the outer ring of the feed pipe, and a brush ring is provided on the baffle along the outer ring of the feed pipe. The brush ring is configured to consist of brushes protruding from the baffle.

[0004] However, in the current existing technology, the feed hopper of the ball mill is mostly designed with an inclined design to facilitate the input of materials into the ball mill from above. Due to the inclined design, the inclined surface of the feed hopper will be continuously impacted by the crushed materials for a long time. Therefore, it is the area of the feed hopper that is most severely worn and is also the main reason for the maintenance and replacement of the feed chute. However, since the damage caused by the mineral materials to other areas is relatively small, it is costly to replace the entire chute just because of the damage to the inclined surface, and the replacement frequency is high.
