Abstract
The utility model relates to a roller sleeve for a powder grinding device. The roller sleeve comprises a sleeve body, wherein two margins of an inner ring of the sleeve body are respectively provided with a raised clamping ring for clamping the shaft roll, and the two margins of the inner ring of the sleeve body are also respectively and externally connected with semi-annular edges which are distributed in a staggered manner; the sleeve body at least has one radial fixing hole; an outer ring of the sleeve body is uniformly provided with projections, and two symmetric radial fixing holes which are communicated with each other are formed in the sleeve body. The roller sleeve has the characteristics that the structure is reasonable, convenience in use and installation can be realized, convenience in installation and repairing can be realized under the situation of guaranteeing high wear resistance and high rigidness, and the like.
Description
Technical field
The utility model relates to a kind of roller shell for abrasive dust equipment, belong to rolling equipment technical field.
Background technology
Flour mill is the visual plant on the construction material production lines such as cement, it is mainly used in the fragmentation processing to raw material, because this flour mill adopts the roll surface of roller shell, raw material is carried out to fragmentation processing, therefore can be referred to as again roll squeezer, roller shell roll surface wherein requires very wear-resisting and possesses very high hardness, also require between roller shell and beaming roller easy to assemblyly simultaneously, be convenient to be convenient for changing after damage; But existing roller shell has only been considered its wearability and hardness, only in selection, write an article, seldom in the structure of roller shell, consider, therefore its unreasonable structure, using installation and maintenance is not easily, cannot meet user's objective demand.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of rational in infrastructure, easy to install and use, can be in the situation that ensureing to have compared with high-wearing feature and hardness, and the roller shell for abrasive dust equipment being easy to install and maintain.
The purpose of this utility model completes by following technical solution, and it comprises a body, and the limit, two ends of body inner ring is provided with the collar for clamping beaming roller of projection, and on limit, two ends, is circumscribed with respectively the semi-ring limit that mutual dislocation is arranged; On described body, at least offer a radially fixing hole.
On the outer ring of described body, be evenly equipped with projection, on described body, offer the radially fixing hole that two symmetries communicate.
The utlity model has rational in infrastructurely, easy to install and use, can ensure have compared with high-wearing feature and hardness in the situation that, the feature such as be easy to install and maintain.
