Problems solved by technology

Since the roller sleeve is a consumable product, many domestic manufacturers use high wear-resistant alloy materials to make it in order to improve its service life, which greatly increases the production cost of the roller sleeve. It can only be returned to the furnace for recasting, which greatly increases the production cost of the manufacturer and does not conform to the development principle of "reduction, reuse, recycling, and remanufacturing" of circular economy

Embodiment Construction

[0014] The following examples are used to illustrate the present invention, but are not used to limit the scope of the present invention, all equivalent technical solutions also belong to the category of the present invention, and the patent protection scope of the present invention should be defined by each claim.

[0015] From figure 1 It can be seen from the figure that a surfacing composite grinding roll includes a grinding roll sleeve 1, a shaft sleeve 6 and a grinding shaft 7, the shaft sleeve 6 is set on the grinding shaft 7, and the grinding roll sleeve 1 passes through the cone Wedges 4 and several evenly distributed bolts 5 are fixed on the shaft sleeve 6 , and there is a welding layer 2 on the outer surface of the base layer 3 of the grinding roll sleeve 1 .

[0016] In order to ensure that the wear resistance of the grinding disc 8 and the grinding roller sleeve 1 are basically consistent, the surfacing layer 2 of the same material is also surfacing on the grinding...

Abstract

The invention discloses a surfacing composite grinding roller applied to pulverized coal grinding equipment in the fields of electric power, metallurgy, coal, iron and steel and coal chemical industry. The surfacing composite grinding roller comprises a grinding roller sleeve, a shaft sleeve and a grinding shaft. The shaft sleeve is sheathed on the grinding shaft; the grinding roller sleeve is fixed on the shaft sleeve; and the outer surface of a base layer of the grinding roller is provided with a surfacing layer. The base layer is prepared from material with high toughness and good thermal stability through one-step casting forming; the surfacing layer made of high wear-resistant and heat-resistant material is deposited on the base layer, so as to solve a series of problems of an existing grinding roller sleeve. The surfacing composite grinding roller has the advantages of long service life, safety, reliability and low manufacturing cost; and at the same time, the surfacing layer can be reused in surfacing compound, so as to meet the requirements of the development of circular economy.

Description

technical field [0001] The invention relates to a grinding device for pulverized coal in electric power, metallurgy, coal, iron and steel, coal chemical industry, etc., in particular to a grinding roller on the grinding device. Background technique [0002] Coal is needed in industries such as electric power, metallurgy, coal, steel, and coal chemical industry, but these coals must be ground into coal powder of a certain particle size before use, so these manufacturers use grinding equipment to grind coal . In the grinding equipment, the grinding roller is the main component for crushing and crushing the material. It is composed of a grinding roller sleeve, a shaft sleeve and a grinding shaft. As a key component for grinding, the grinding roller sleeve not only affects the service life The level of output and the safe operation of roller sleeves at the same time determine the realization of the production efficiency of the enterprise. During the grinding process, various m...
