The multi-cylinder cone crusher has high efficiency, low energy consumption and uniform product granularity, is suitable for medium and fine crushing of various ores and rocks, and is widely applied to multiple industries such as metal mines, metallurgy, cement, sand and stone. In the working process of the crusher, the size of a discharge hole between parallel areas at the bottom of the moving cone lining plate and the fixed cone lining plate directly influences the discharge granularity of the crusher and the production efficiency of the crusher. In the operation process of the crusher, the impact and the extrusion of ores and the friction between materials and lining plates can cause the abrasion of the fixed cone lining plate and the movable cone lining plate, so that the discharge opening is enlarged, and the size of the discharge opening must be adjusted regularly to ensure the product quality. For multi-cylinder cone crushers, the discharge outlet is generally adjusted once a week, and the lining plates are periodically replaced for 3-5 months. Therefore, the discharge opening can be adjusted more quickly, accurately and conveniently, so that the crusher has very important significance for ensuring the working efficiency of the crusher, and meanwhile, the automatic adjustment of the discharge opening has important significance for the intellectualization of crushing.

The multi-cylinder hydraulic cone crusher can not be avoided in the operation process, iron blocks and the like can not enter a crushing cavity through the crushed objects, and when the crushed objects cannot enter the crushing cavity, if the crushed objects cannot be discharged in time, huge damage can be caused to the crusher, so that the crusher still needs to pass through an iron protection and cavity cleaning device, and non-crushed objects in the crushing cavity are removed in time.
