The Dominant Place of Vertical Impact Crusher

A large number of gravel field in North America use the Ellay VSI vertical shaft impact crusher produced bySand Cedarapids.   The biggest characteristic of this type of machine is the running speed  is faster than Bamare type, therefore, the wear of the impeller and anvil hoop are relatively small ,but the product qualified grain output rate is high . The Original Nordberg launched VI series of vertical shaft impact crusher, its structure is basically similar to Cedarapids production Ellay VSI type , the difference is that the outer ring lining, drum liner can "rotate", The idea is to make the bushing continue work in rotation to extend life, but  if we analysis from structure , when the roller was filled materials constantly ,the rotating roller will lose its rotating characteristics,  In addition, non-positive impact between the material and the drum speeds up the local wear of the roller. VI model is actually the Svedala rotor, Nordbert, drum liner ring.so the the Svedala rotor inadequacies  exists in Nordberg also.
 It is Recently reported that Svedala launched the production which is similar with Cedarapids EIJay's vertical shaft impact crusher  type ,  I believe Nonlberg is bound to change the design of the VI series and go EllayVSI broken machine road in future. Shanghai Dowling Watson Machinery Co., Ltd. has developed PLC series vertical impact crusher. The model prototype is the U.S. the Cedarapids company C vertical shaft impact crusher which characterized by simple structure, large capacity, unobstructed discharge and both can be used to crushing and devoted to sand, the product grain shape is good. It contains Φ is 900 mm, φ1 000 mm φ1170 mm 3 total sizes. Shanghai Longyang Machinery Factory absorb the successful experiences of the domestic and international vertical shaft impact crusher, exposed the  old  problems in use and  improved, now , assessment of industrial operation is completed , which the styling products will promoted to market: Zhengzhou Yifan  Mechanical Equipment Co., Ltd. constantly improve the product on the basis of years of sales,which is now maturing, the structural strength and stiffness are greatly improved, especially the improvement in the structure and material impact heads, after the long-term using, its life is over the import prototype (in the same conditions) and  leap to the domestic advanced level. Vertical impact crusher manufactured by the company ranks first in China's domestic market share.
