Description

Technical Field

[0001] The invention relates to the technical field of alloy roller sleeves, in particular to a modular alloy roller sleeve. Background Art

[0002] Roller mill is a kind of mining machinery that uses the pressure generated by the rolling of two rollers to crush and grind the passing materials. It is widely used in many industries such as metallurgy, mining, building materials, power generation and chemical industry. The wear resistance of the roller surface material determines the crushing accuracy of the material and the service life of the wearing parts.

[0003] At present, the roller surface of the roller mill mainly adopts composite wear-resistant materials, and processes such as gluing and inlaying cemented carbide are used to improve its service life. As the direct working surface for material processing, the roller surface is subjected to high impact loads and wear consumption. The roller surface wear and alloy shedding processed by the existing process are relatively serious. Daily maintenance is usually carried out by surfacing wear-resistant materials, replacing and supplementing alloy studs, etc., which has a large workload, high labor intensity, and low safety factor for personnel; the performance of the sleeve and shaft material is reduced after the high-temperature repair construction of the roller surface; when the roller surface is severely worn, the entire set of roller shaft body needs to be disassembled and returned to the factory for repair or scrapped and replaced. Long-term shutdown maintenance directly reduces the utilization efficiency of the equipment, and the replacement of the roller shaft body additionally increases the maintenance and use cost of the equipment. With the demand for efficient production and processing, the manufacturing and use of large and heavy roller mills have increased, and the processing difficulty and maintenance and replacement cost of the roller surface have increased accordingly.

[0004] For example, the Chinese patent with publication number CN218796223U effectively solves the above problem. However, the segmented roller sleeve in the above patent has a high density and multiple transverse gaps. Under long-term wear, the gaps may expand, causing the two parts to collide and cause damage.
