VSI series crushers(Sand Making Machine) made by kefid are specially designed for sand making and trueing of various stones and rocks. Kefid has developed internationally advanced patent technology which is able to provide users with high efficiency, less using cost. We have two types of VSI crusher: Deep Rotor VSI Crusher and B Series VSI Crusher. They are suitable for medium and fine crushing of different hardness of varied ore and rock, such as iron ore, nonferrous ore, diamond, bauxite, quartz sand, corundum, perlite, basalt and other aggregate material’ medium and fine crushing.
Deep Rotor VSI Crusher
Deep Rotor VSI Crusher integrates many patents and three crushing methods, is a new and high efficiency crusher. The rotor of deep rotor VSI crusher has been specially optimized design, which makes the capacity increased by about 30%. Around guard adopts innovative design to improve the service life of over 48%. Increase vice hammer to prevent from damaging the side plate after the main hammer wear and tear. The most key wear resistant material uses wear resistant and high temperature resistant material in American important area. Japanese hydraulic opening cover device is originally imported.

B Series VSI Crusher
B series VSI crusher is newly researched equipment, with international advanced level. The machine is specifically for the production of high-quality gravel aggregate used in highway, railway, high-rise buildings, municipal, hydroelectric dam construction, and concrete mixing sand, and it is the first choice of the artificial sand making area and stone shaping area. It is applicable to the fine crushing techniques in the front of mining sector, and applicable to the material crushing of building materials, mining, refractories, cement, and abrasive industry. Besides, it also can be used in highly abrasive material and secondary disintegration crushing of it.
