Description

Technical Field

[0001] This application relates to the technical field of engineering equipment, and in particular, to a wear-resistant single-roll crushing roll. Background Art

[0002] A crusher is a commonly used heavy machinery. The single-roll crusher for sintered ore is an important part of the sintering plant in iron and steel enterprises. It is used to crush large hot sintered ore cakes unloaded from the sintering machine. After crushing, the particle size is less than 150 mm to meet the subsequent process requirements of the sintered ore. Its working temperature is as high as (750~850)°C to 1000°C, and it works in a high-temperature, dusty and heavy-load environment for a long time.

[0003] The harsh working environment makes the service life of the single-roll crusher very short. The hammer head part generally lasts for (3~5) months, that is, it cannot be used continuously due to severe wear. Since the toothed roll is heavy and the disassembly is complex, the replacement or repair is time-consuming and laborious, which restricts the production of sintered ore and thus affects the steel output.
