Compound Cone Crusher Compound Cone Crusher, widely used in the industries of metallurgy, building material, road construction, chemical engineering & silicate, is suitable for crushing all kinds of ores and rocks with medium or above hardness. Compound Cone Crusher is divided into standard type and short-head type. Generally speaking, the standard type has big feeding granularity and relatively coarse discharging granularity, and the short-head type has steep crushing cone and small feeding granularity which is conducive to producing fine particle materials, for this reason,the standard type compound cone crusher is generally used for coarse and medium crushing and the short-headed type compound cone crusher is generally used for medium and fine crushing. Compound Cone Crusher Features: It has unique hydraulic clearing system,hydraulic opening adjusting function,easy for changing movable and fixed plate,decreasing management and maintenance cost. It is widely used for medium and fine crushing of granite,basalt,cobble,cobblestone,iron ore etc, which is well received by customers. Working Principle : Cone crusher when working, the motor drives the eccentric bearing via the spring coupling, the transmission shaft and a couple of cone gear wheels. The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner, and sometimes far away from the bowl liner. The raw materials are pressed, impacted and finally crushed in the copper.
