Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0030] Such as Figure 1~5 As shown, a pulverizer includes a housing 1, a gear 11, a reduction motor 3 and a bearing seat 2, the two ends of the housing 1 are rotatably connected to the bearing housing 2, and the outer wall of the housing 1 is provided with a gear , the gear meshes with the output wheel of the reduction motor 3, the housing 1 includes a feed end and a discharge end, the feed end is higher than the discharge end, and the diameter of the housing 1 is from the feed end to the discharge end. The end is stepped and reduced; the housing 1 is provided with a partition ring 6 that divides the housing 1 into a plurality of cavities along the feed end to the discharge end, and each of the cavities is provided with multiple cavities. A steel ball 8 and a plurality of guide grooves 7, a plurality of said guide grooves 7 are arranged in an annul...

Abstract

The invention relates to a grinder. The feeding end of a shell is higher than the discharging end, and the diameter of the shell decreases from the feeding end to the discharging end in a stepped mode; and a plurality of guide edges and a plurality of separation rings are arranged on the inner surface of the shell, the separation rings divide the inside of the shell to form a plurality of cavities, each of the cavities is internally provided with a steel ball, and the separation rings are perpendicular to the axis of the shell. The separation rings, the guide edges and material passing holes screen the ground materials in the cavities, the finely ground materials are transferred to the next cavity to be ground, the situation that fine particles absorb the impact energy of the steel balls when being mixed with coarse particles is avoided, the impact strength of the steel balls is ensured, the ground materials can be classified with multiple particle sizes, the steel balls of different proportions are used for grinding materials of different particle sizes, and the grinding efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of material pulverization, in particular to a pulverizer. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. This type of grinding machine is filled with a certain number of steel balls in its cylinder as the grinding medium. [0003] It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, glass ceramics and other production industries, for dry or wet grinding of various ores and other grindable materials; Ball mills are suitable for grinding various ores and other materials, and are widely used in mineral processing, building materials and chemical industries. [0004] The patent document with the authorized notification number CN203750630U discloses a ball mill with a ball mill baffle. direction, the length is one eighth to one tenth of the diameter...
