Adaptive adjustment hammer wheel of vertical ring mill

Abstract

The invention discloses a self-adaptive control hammer wheel for a vertical ring mill. The hammer wheel is arranged on a hammer wheel seat, wherein the hammer wheel seat is arranged on a hammer wheel shaft through a self-aligning bearing; a sealing device is arranged among the upper side and the lower side of the hammer wheel and the hammer wheel shaft. The hammer wheel seat is arranged on the hammer wheel shaft through the self-aligning bearing, and a deflection angle can be formed between the hammer wheel shaft and the outer ring of the self-aligning bearing; the self-adaptive control hammer wheel has the characteristics that firstly, materials entering the hammer wheel and a milling ring can be grinded and milled, so that the materials with smaller sizes are prevented from passing through the hammer wheel and the milling ring under the condition of no grinding as much as possible; secondly, during the grinding process, the upper end and the lower end of the hammer wheel and the milling ring can be used for grinding simultaneously, so that the abrasion at the upper end and the lower end is uniform; thirdly, a spherical surface sealing structure is adopted, and sealing can also be ensured when the hammer wheel deflects.

Description

technical field [0001] The invention relates to a hammer wheel of a vertical ring mill. Background technique [0002] In the existing ring rolling mill technology, the grinding principle is that through the centrifugal movement of the hammer wheel, the grinding force formed by the hammer wheel on the grinding ring crushes the material, and the hammer wheel surface and the grinding ring surface are always maintained. Parallel, that is, the rolling distance between the hammer wheel surface and the rolling ring surface is the same in the upper and lower rolling areas. During the rolling process of the material, it first enters the upper end area between the hammer wheel and the rolling ring. When the material enters this area, a larger rolling distance will be formed in this area, and the crushed material will be crushed by the larger rolling distance caused by the larger material without being crushed by the hammer wheel and the rolling ring. , it will cause, first, part of t...

[0002] In the existing ring rolling mill technology, the grinding principle is that through the centrifugal movement of the hammer wheel, the grinding force formed by the hammer wheel on the grinding ring crushes the material, and the hammer wheel surface and the grinding ring surface are always maintained. Parallel, that is, the rolling distance between the hammer wheel surface and the rolling ring surface is the same in the upper and lower rolling areas. During the rolling process of the material, it first enters the upper end area between the hammer wheel and the rolling ring. When the material enters this area, a larger rolling distance will be formed in this area, and the crushed material will be crushed by the larger rolling distance caused by the larger material without being crushed by the hammer wheel and the rolling ring. , it will cause, first, part of the material passes between the hammer wheel and the grinding ring without being crushed, so that this part of the material cannot be crushed, reducing the grinding efficiency; second, the formed between the hammer wheel and the grinding ring The upper rolling area often needs to crush some large-sized and high-hardness materials, while the working conditions in the lower rolling area are opposite, so that the hammer wheel and grinding ring in the upper rolling area wear faster, and the upper and lower ends wear unevenly
