Abstract
The utility model discloses a wear-resistant grinding roll for a vertical coal grinder, comprising a grinding roll main body, wherein a wear-resistant compound sleeve is surfacing-welded on the working wall of the grinding roll main body. Therefore, when the vertical coal grinder using the grinding roll works, the wear-resistant compound sleeve on the working wall of the grinding roll main body interacts with to-be-crushed solid particles, and the direct contact of the grinding roll main body with the to-be-crushed solid particles is avoided, thus protecting the grinding roll main body, and enabling the grinding roll main body to be not easy to wear; and therefore, the grinding roll main body has no need to be replaced by a new one in quite a long time, thus decreasing the production cost and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of grinding roller, relates in particular to a kind of abrasive roller that is used for vertical spindle coal pulveriser.
Background technology
At present, vertical spindle coal pulveriser is owing to have that efficient height, volume are little, advantage of low energy consumption has obtained in fields such as power plant, cement plants using widely, and grinding roller is that vertical spindle coal pulveriser is broken, the most important parts of abrasive solid particle; Yet, expensive grinding roller with the mill processes of immobilized particles in the phenomenon of wearing and tearing takes place easily, cause its work wall pit bit to occur; Can reduce its work quality greatly like this, the small product size that obtains of causing milling is excessive, does not reach the standard of people's expection; The grinding roller that so will force people more to renew; Not only improve production cost, and changed grinding roller and need expend time in, therefore also can reduce production efficiency.
Based on this, people press for a kind of abrasive roller that is used for vertical spindle coal pulveriser of difficult generation wearing and tearing, the purpose that reduces production costs, enhances productivity to reach.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of abrasive roller that is used for vertical spindle coal pulveriser, and it is difficult for wearing and tearing, and can reduce production costs, and enhances productivity.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of abrasive roller that is used for vertical spindle coal pulveriser comprises the grinding roller main body, and built-up welding has a wear-resisting compound cover on the work wall of said grinding roller main body.
As a kind of preferred version, said wear-resisting compound cover is made up of interior supporting layer and outer wearing course, and this outer wearing course built-up welding is in the surface of interior supporting layer.
As a kind of preferred version, the thickness of said outer wearing course is the 60-80 millimeter.
As a kind of preferred version, said outer wearing course is a high chromium cast iron layer.
As a kind of preferred version, the thickness of said interior supporting layer is the 4-5 millimeter.
As a kind of preferred version, said interior supporting layer is the steel alloy layer.
A kind of abrasive roller that is used for vertical spindle coal pulveriser that the utility model is set forth; Its beneficial effect is: this product is that wear-resisting compound cover interacts with treating broken solid particle during use, thereby has protected the grinding roller main body through built-up welding one wear-resisting compound cover on the work wall of grinding roller main body; Make the grinding roller main body be difficult for wearing and tearing; In considerable time, do not need the grinding roller main body that more renews like this, therefore reduced production cost, improved production efficiency.
Description of drawings
Fig. 1 is the configuration diagram of the utility model embodiment.
Description of reference numerals:
10, grinding roller main body 20, wear-resisting compound cover
21, interior supporting layer 22, outer wearing course.
The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please with reference to shown in Figure 1, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of abrasive roller that is used for vertical spindle coal pulveriser; Comprise grinding roller main body 10; Built-up welding has a wear-resisting compound cover 20 on the work wall of this grinding roller main body 10, and said wear-resisting compound cover 20 is made up of with outer wearing course 22 interior supporting layer 21; Be somebody's turn to do outer wearing course 22 built-up welding in the surface of interior supporting layer 21, wherein:
Said outer wearing course 22 is a high chromium cast iron layer, and the thickness of this outer wearing course 22 is the 60-80 millimeter.
Supporting layer 21 is the steel alloy layer in said, and thickness of supporting layer 21 is the 4-5 millimeter in this.
During use; Described outer wearing course 22 cooperates with the mill of vertical spindle coal pulveriser to mill treats broken solid particle, treats that broken solid particle and outer wearing course 22 interact, and grinding roller main body 10 will can directly not contact with solid particle at this moment; Therefore be difficult for taking place the phenomenon of wearing and tearing; Thereby prolong its working life greatly, in considerable time, do not needed the grinding roller main body 10 that more renews, and; Even outer wearing course 22 or whole wear-resisting compound cover 20 wearing and tearing occurred after long-time the use, but also new outer wearing course 22 or the whole wear-resisting compound cover 20 of built-up welding continues to protect grinding roller main body 10.
The design focal point of the utility model is: this product is through built-up welding one wear-resisting compound cover 20 on the work wall of grinding roller main body 10; Be that wear-resisting compound cover 20 interacts with treating broken solid particle during use; Thereby protected grinding roller main body 10, made grinding roller main body 10 be difficult for wearing and tearing, in considerable time, do not needed the grinding roller main body 10 that more renews like this; Therefore reduce production cost, improved production efficiency.
The above; It only is the utility model preferred embodiment; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
