Stone making machine the vertical shaft impact crusher, also called sand making machine and rubble shaping machine, is a kind of crusher impacted by the materials the mselves. It is of high energy but low consumption and of intemational anvanced level developed by introducing fo reign outstanding technology of the same type of products. At present, it is the most advanced and practical equipment for medium-sized and fine crushing and shaping. Stone making machine is widely used for medium-sized and fine crushing and shaping in the following industries: Minerals, quarry, abrasive, cement, refractory materials, alumina, quatrzsand, emmery, glass and so on. Operating Principle: The materials fall into the impeller from the head of the maching and with the function of high-speed centrifugal force, they strongly hit against and highly grind the other parts of the materials bypass flowing around the impller in an umbrella form. After mutual impaction and between the impeller and the machine shell, the materials will move like a vortex and will be impacted, rubbed and pulverized many times. Then they will come fo the required fineness controlled by screening equipment, and discharge from the bottom of the machine. Features: 1 it features of simple structure, high crushing efficiency and low production cost. 2it can fine crush and crude grind materials, and the crushed products are of cubic shape. 3the influence from the water in materals to the machine is little. 4it is suitable for srushing materals of medium, high and super hardness. 5it works by stones hitting stones, so there is ilttle wear for the machine and it can save energy and is of low consumption. 6the grade and the fineness of the sand for construction after being washed can be up to the national stabilization, low noise. And because it crushes materials in the cavity, the dust pollution is little. 8when used along with the rod mill and ball one, it can simplify the flowing process, lessen the energy consumption, improve the production efficiency and cut down the cost to a large degree.
