The function of High Efficiency Sand Maker : The Vertical Shaft Impact Crusher is also called Sand Maker .Our company develop this domestic,international ,advanced level efficient crushing equipment combining the actual situation in domestic sand making ,and it is based on the “stone hit stone ”principle and technology .It is widely used in all kinds of hard and brittle materials for medium ,fine crushing .Such as ,rocks ,abrasive ,refractory,cement clinker ,quartz,iron ore and concrete aggregate and so on . And building sand ,building road gravel are the most appropriate . Operating principle of sand maker : The materials vertically fall into the impeller through high-speed rotation from the top of the machine .Under the high-speed centrifugal force ,the materials shunted with another part around the impeller in the form of the umbrella produce at a high speed,striking and crushing .Materials which not bumping into each other ,can form vortex striking with each other between impeller and case .And then they will be discharged from the under part directly , forming a lot of circulation of closed path .They will reach the required size through the controlling of the sieve . Features : 1 The structure is simple and reasonable ,the operating cost is moderate . 2 High broken rate ,saving energy . 3 Have the function of fine crushing and coarse grinding . 4 Little influence by the water content ,water content can reach about 8% . 5 Best for crushing medium hard and especially hard materials . 6 Excellent product grain size ,cube shape ,very few is pin sheet . 7 The impeller is less wear and tear ,easy maintenance . 8 The working noise is not more than 75 decibel . 9 Easy operating and maintenance .
