PYF series compound cone crusher widely used in metallurgical industry, building materials industry, road building industry, chemical industry and industrial acid, applied to middle-and middle-broken over the hardness of ore and rock, this machine has broken force, high efficiency , high capacity, low cost movements, to facilitate adjustment, the use of economic, and other characteristics. As part of rational design and material selection, the long service life, and the compound cone crusher of broken uniform size, reduces the load cycle, in the medium and large-sized stone crushing machine, using a hydraulic-chamber system, reducing downtime, and each specification of the cavity-breakers, according to different user needs, choose a different type cavity, to better adapt to user needs. The use of grease-sealed sealed to prevent the water supply and drainage systems easy to plug the shortcomings of the oil-water mixture and the shortcomings, the insurance system is the spring overload device, a foreign body, broken through the iron cavity without endangering crusher. The plane is divided into standard and short-head, in general, the standard size-feeding, nesting size also coarse, short-head over the steep broken cone, feeding small size is conducive to production of fine-grained Grade materials, the standard generally used for rough, broken, short for the first type, grinding.
