Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grinding equipment, relates to a roller press grinding roller, and particularly relates to a split-type grinding roller sleeve. Background Art
[0002] As an energy-saving grinding equipment used to replace the ball mill pre-grinding system, the roller press has the advantages of simple structure, small volume, low energy consumption, high efficiency, etc., and is widely used in the cement industry. During production, the grinding roller sleeve on the roller press is prone to wear and damage due to direct contact with materials. It is a vulnerable roller pressing part on the roller press, and its quality directly affects the overall production output, quality, and operation cost. Therefore, the sleeve plays a very important role in the use of the roller press.
[0003] Currently, the grinding roller sleeves all adopt an integral design. When the wear caused by long-term operation is serious and it can no longer be used, the entire grinding roller needs to be removed from the roller press to replace the sleeve. The replacement and repair processes are complex, with a large workload, long time consumption, and cumbersome construction. Moreover, sometimes only part of the grinding roller sleeve is worn. If the whole is replaced, it will increase the production cost, which is not conducive to the development of the enterprise.
[0004] Patent CN218742233U discloses a detachable grinding roller sleeve for a medium-speed coal mill, which includes a grinding roller sleeve carcass and an outer anti-wear component. Based on the grinding roller sleeve carcass as the basic part, the ends of several outer anti-wear components are abutted and spliced on the grinding roller sleeve carcass through sliding grooves, and the outer anti-wear components are fixed on the grinding roller sleeve carcass by screws. The utility model only needs to replace the severely worn part without replacing the whole grinding roller sleeve, effectively shortening the maintenance time.
[0005] However, the grinding roller sleeve described in the above patent still has some problems: the outer anti-wear components are spliced by fitting, and do not form an integral grinding roller sleeve. There is no mutual force between adjacent anti-wear components, which easily affects the stability of the sleeve, reduces the strength and durability of the structure, and needs to be fixed by multiple screws, making it difficult to disassemble, greatly increasing the production cost and workload. Summary of the Utility Model
