Abstract

The utility model discloses a medium-speed coal mill roller sleeve with metallic ceramic composite, which comprises a roller sleeve body. A composite grid made of high-chromium alloy and ceramic particles is compounded onto the surface of the roller sleeve body. The medium-speed coal mill roller sleeve is reasonable in structure, can effectively meet work condition requirements of equipment crushing resistance and wear resistance, can prolong service life by more than multiple times, and accordingly realizes long service life, and stable and reliable production in use of equipment.

Description

Medium-speed pulverizer grinding roller cover with cermet compositions
Technical field:
The utility model relates to a kind of medium-speed pulverizer grinding roller cover.
Background technology:
Existing medium-speed pulverizer grinding roller cover (comprising HP, MPS type etc.) generally adopts the high-chromium alloy casting to form, higher extruding force, shearing force are born in the work because surface, general 8000~12000 hours life-spans, roller surface after the wearing and tearing forms groove and waveform pit, common process adopts built-up welding, returns to original size and continues to come into operation.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, anti-fragmentation, the medium-speed pulverizer grinding roller cover with cermet compositions that wear resistance is good.
Technical solution of the present utility model is:
A kind of medium-speed pulverizer grinding roller cover with cermet compositions comprises grinding roller cover body, it is characterized in that: the composite gridding that high-chromium alloy and ceramic particle are arranged in the surface recombination of grinding roller cover body.
The composite gridding of grinding roller cover body and high-chromium alloy and ceramic particle links into an integrated entity by pouring type.
The utility model is rational in infrastructure, and the equipment that can effectively reach is anti-broken, working condition requirement resistance to wears.Can improve or prolong more than the service life several times, long thereby the equipment use reaches the cycle, produce stable, reliable.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
Embodiment:
A kind of medium-speed pulverizer grinding roller cover with cermet compositions comprises grinding roller cover body 1, and the composite gridding 2 of high-chromium alloy and ceramic particle is arranged in the surface recombination of grinding roller cover body.
The composite gridding of grinding roller cover body and high-chromium alloy and ceramic particle links into an integrated entity by pouring type.
