Granite has is the the oldest application and most widely used, but also the most common crustal rocks. Granite, basalt, diabase, river pebbles stone have high hardness and high silicon content, they are hard to crush. Therefore, in the actual situation of crushing, investment cost of the production line and practicality issues must be considered,in order to get the maximum return on investment.In many stone quarry that has less demanding for grain type, customers are more willing to use the production line made up of jaw crusher, fine type jaw crusher or cone crusher. Jaw crusher and cone crusher belong to squeeze crushing, the influence on wear parts is relatively small, the used stone crusher in south africa barite ore mineral grinding machine production cost would be relatively low. The biggest feature of impact crusher lies in its producing of the material with good particle size. It owns the double functions of crushing and shaping. The stone with good particle size can increase the bearing capacity of the building. But its wearing parts have higher cost than that of the fine type jaw crusher and cone crusher. Thus, impact crusher low intensity magnetic separator mainly provides excellent stone with the highway, railway, airport, port, high-rise buildings etc.Shanghai Zenith Machinery Equipmenthas accumulated broad industry experience, not only has a first-class design team, is also rapidly expanding domestic and international cooperation. The range of use has rapidly around the world. Zenith jaw crusher has large crushing ratio, deep crushing chamber and no dead zone, increasing feeding capacity and output. Wide range of adjusting of the discharge opening, fully meet the feeding and out of the material.
