Four Main Types of Secondary Stone Crusher

The working principle of crushing process is not difficult, but the accomplishment needs to be supported by high quality machine. The hard rocks are placed between two solid surfaces and while the surfaces move against to each other, the materials can not withstand the pressure and they will be broken into pieces. Toggle crusher is a popular type which complete crushing process with series of jaws. The distance between the jaws at the top is much farther than at the bottom. So, the materials will become smaller and smaller while they are flowing down in the cavity.There are mainly four modes of secondary crusher: gyratory crusher, cone crusher, roll crusher and impact crusher. Each of them has its own features and applications. The materials in gyratory crushers are broken down by the pressure that comes from the spindle and hopper. The rocks are pressed by the hopper and spindle. To prolong the lifespan of the spindle, it is protected by a durable mantle. The rocks are being crushed until the size is small enough to pass the discharging opening.The crushing process of cone crusher is similar with gyratory crusher. But the crushing zones are much parallel. Some engineers describe the working of cone crushers as the daily juicer. As the name of roll crusher implies, it takes advantage of two steel wheel to accomplish crushing. The rocks are crushed between the two wheels. Impact crusher is the commonly used crusher and it is one of our hot-sale products. According to the design of impact crusher, it can be separated into two types - the horizontal shaft impact crusher and the vertical shaft impact crusher. The latter uses velocity to crush rocks while the former uses hammers to achieve the same purpose.Generally, secondary stone crusher need to cooperate with its primary counterpart. The size of rocks which can be crushed by secondary crushers are much smaller than the size that can be crushed by primary crusher. To reduce the size of rocks fed into secondary...
