Cone Crusher is widely used in some trades like metallurgy, building materials, road building, chemicals and silicate industry. Taper crusher is applicable for various ores and rocks of medium break hardness or above. Taper crusher has strong break force, high efficiency, large process quantity, low operation cost, easy adjustment and economical application. For it has reasonable parts materials and structural design, it has long service life and even break granularity to reduce circulation load. For the middle and large crushers, hydraulic pressure chamber-cleaning system is adopted to reduce the stop time. And the chamber type of different crushers can be selected by users according to their demand. Taper crusher is sealed with lubricate grease to avoid the block of water supply and drainage system and the mixing of water and oil. Spring insurance system is overload protection device to make extraneous substances and iron pieces pass breaking chamber not to damage crusher. Trapper crusher includes standard type and short-end type. Generally, the standard type works for large feed grains and discharged grains are rough and the short-end type has steep break wimble and works for small feed grains and produce of fine materials. So the standard type is always used for rough and medium materials break and the short-end for medium and fine materials break.
