Abstract
The utility model discloses a composite wear-resistant grinding roller, which belongs to parts of a grinding machine, in particular to a grinding roller of a Raymond mill used for milling power. The composite wear-resistant grinding roller comprises a grinding roller body provided with a central tapered hole, and is characterized in that the grinding roller body includes the grinding roller body and a wear-resistant bushing ring installed at the outer periphery of the grinding roller body. In the utility model, an original grinding roller body made of a single material is changed into the composite wear-resistant grinding roller including the grinding roller body and the wear-resistant bushing ring installed at the outer periphery of the grinding roller body; the grinding roller body can be made of general materials, so that the cost can be reduced; the wear-resistant bushing ring is made of wear-resistant alloys, so that the wear-resisting property thereof is good and the service life is long; and when the wear-resistant bushing ring is seriously worn down, the grinding roller can be reused again as long as the wear-resistant bushing ring is replaced, therefore, the material is saved and the use cost is reduced.
Description
Technical field
The utility model belongs to the grinding roller of the Raymond mill that the parts of disintegrating apparatus, particularly abrasive dust use.
Background technology
Conventional industrial powder manufacturing apparatus adopts the Raymond mill powder more, this equipment is compared with ball mill has the little advantage of noise, but because the manufacturing expense of the main working parts grinding roller of this equipment, bull ring is higher, and the life-span is shorter, can only scrap processing after being ground to certain limit, have the higher weakness of use cost.
The utility model content
In order to overcome short deficiency of existing grinding roller life-span easy to wear, the purpose of this utility model provides a kind of compound wear-resistant roll, and this compound wear-resistant roll not only wearability is good, and is convenient to repair.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of compound wear-resistant roll, comprise the grinding roller body that has the tapered centre hole, and it is characterized in that: form by grinding roller body and the wear-resisting grommet that is installed on the external circumference of grinding roller.
Described wear-resisting grommet is made by antifriction alloy.
The utility model is with original grinding roller body of being made by homogenous material, be transformed into by the grinding roller body and be installed in the compound wear-resistant roll that the wear-resisting grommet on its excircle is formed, the grinding roller body can be made and can reduce the cost with common material, it is long that wear-resisting grommet is made the good life-span of its anti-wear performance with antifriction alloy, after wear-resisting grommet serious wear, can only change wear-resisting grommet, grinding roller is utilized again, can economical with materials and use cost.
