In Italy ,South Africa ,Spain ,India ,Taiwan and such other countries whose stone material industry have high level are widely using the common large abrasion block polihsing machines to process the facing slabs . These machines have high price (approximately millions of dollars ) and high using cost ( the power is about 120-130 KW ) In China ,except few enterprises which use the common four or six paws abrasion disk to process the facing slabs ,most of the stone proceesing enterprises adopt the hand-guided form or bridge form of polishing machines which have low price and low efficiency and are popular at the early days in the stone material industry . At that time ,the cost of the labor is low and now with the development of the China economy , the cost of prosuction rise along with the rise of the labor cost . Now the multi-disc bridge polihing machi ne are widely used in China , Its application greatly improve the production efficiency low the labor cost and save the labor intensity .But this kind of machine has some insurmountable faluts which are : needing to stop the machine and replace the abrasive disk frequently ; too complicated of the slab loading and unloading ; needing to adjust the stroke each loading ; can not process the varied length of slabs at the same time . Due to that reason and in order to adjust to the current developing situatin of the industry , our company has researched and deveolpped the RPM09/9 multi-Resin abrsive enterprises ,and it illustiates a good prospect of application and extension .
