Cone crusher is widely used in metallurgy industry, building materials industry, road building industry, chemical industry and silicate industry, apply to broken above the middle-and middle-hardness of various minerals and rocks, this machine has broken force, high efficiency, processing a high level, action, low cost, easy to adjust, the use of economic and so on. As part selection and structural design is reasonable, so long life, while the broken products, uniform particle size, reducing the cycle load, in the medium to large-sized crusher, using the hydraulic system, clear cavity, reducing downtime, and each specifications crusher cavity multi-users according to different needs, choose a different cavity type, in order to better adapt to user needs. The machine seals with grease seal, avoiding the water supply and drainage system easy to plug the shortcomings and deficiencies in water and oil miscible, springs insurance system is overload device can be combined foreign body iron through the crushing chamber without detriment to the crusher. The machine is divided into standard and short head type, in general, standard feed size large, size is also discharging coarse, short head cone crusher type steep, feeding a small size is conducive to producing fine grain size of materials, so standard generally used for rough, medium broken, the short head type is used, the broken bits.
