Description

Technical Field

[0001] The utility model relates to the field of hammer crushers, in particular to a hydraulic adjustment device for a sieve bar frame of a hammer crusher. Background Technique

[0002] A hammer crusher is a device that crushes materials in an impact form. It is divided into two forms: single-rotor and double-rotor. It is a primary crusher that directly crushes materials with a maximum particle size of 600 - 1800 mm to 25 mm or less than 25 mm. The hammer crusher is suitable for crushing medium-hard materials in industrial sectors such as cement, chemical industry, electric power, and metallurgy, such as limestone, slag, coke, coal, etc. for medium crushing and fine crushing operations. It is divided into two forms: single-rotor and double-rotor. The single-rotor is further divided into two types: reversible and irreversible. The single-rotor hammer crusher and the ring hammer crusher are widely used.

[0003] Generally, the hammer head strikes the crushed material to form the first crushing. The crushed material is struck onto the counterattack frame assembly to form the second crushing. The sieve bar frame is an important component of the hammer crusher. It is installed below the rotor. The material is screened through the sieve bar frame. During the process of the hammer crusher crushing the material, due to the inconsistent particle sizes of the crushed material, the sieve bar frame is often blocked, and it is necessary to manually clean the blocked material. Moreover, one side of the sieve bar is severely worn after long-term screening, while the other side is intact, resulting in the sieve bar not reaching the service limit and breaking at the severely worn side, which greatly reduces the service life of a sieve bar. Content of the Utility Model
