Description

Sieve plate for crusher and crusher Technical Field The utility model relates to the technical field of screen structures of crushing equipment, in particular to a screen plate for a crusher. The utility model also relates to a crusher comprising the screen plate for the crusher. Background The crusher is efficient crushing equipment, realizes crushing and screening at the same time by combining a plurality of crushing modes such as impact, shearing, rolling and the like, can continuously roll and strike materials, and can continuously push unqualified particles forwards through a built-in pushing device until the required granularity is reached. The screen plate of the crusher is a key component for realizing effective screening of materials, and the materials are refined in a crushing and screening mode. The maintenance and replacement of the screen panels requires convenience and rapidness to reduce downtime and operating costs. At present, the following problems exist in practical application of a crusher screen plate: 1. after the sieve plate is used for a long time, abrasion can occur due to the impact and friction of materials, and even perforation of the sieve plate can be caused when the sieve plate is serious. 2. In the running process of the vibrating screen, if the screen plate is not firmly fixed, offset or loosening can occur, and the screening effect is affected. 3. Improper assembly of the screen panels may result in poor screening results. 4. The screen plate is inconvenient to install, time and labor are consumed in assembly and disassembly, and the screen plate is generally cast and is difficult to meet design requirements in installation.
