Description

technical field

[0001] The invention belongs to the technical field of rock crusher equipment, in particular to a multipurpose rock crusher for civil engineering. Background technique

[0002] With the development of the modern civil engineering industry, the requirements for civil engineering rock crushers are getting higher and higher. At present, the commonly used crushing machines in civil engineering include jaw crushers and hammer crushers. In the process of use, the noise is too large, the inertial force is large, the load on the parts is large, and the vibration is relatively severe, so the requirements for the firmness of the parts are relatively high. When the feeding is uneven, it is easy to block the crushing chamber, and the vertical stroke of the movable jaw is greatly increased. In addition to energy consumption, the hammer crusher produces a lot of noise during use, and the crushed particles are large, so it cannot process wet stones, and the production effic...
