diamond saw some important influence

1, stone mining technology and equipmentAt present, China still has a lot of stone mines using drill blasting this backward approach to the production of stone blocks, not only productive but also job insecurity, especially due to detonation caused by rock rupture, severely damaged the diamond blade saws  stone resources, produced irregular size of blocks, or even scrapped due to a crack, finished product rate is very low. It is estimated, using drill blasting method mining blocks only 5% to 8% of the extraction can be processed timber. The early 1980s, a number of stone industrialized countries have banned use of blasting mining stone and replaced diamond wire saws and other advanced technologies. Stone can say this is a sign of modern mining technology. The  masonry saw blades  stone mining techniques to measure an important indicator of the degree of modernization is: day number of cubic meters per capita mining blocks. The industry believes that China International Chamber of stone mine production is low. The reason is the lack of mechanized equipment, mining technology behind the production mismanagement. The average annual number of mined stone mines only a few hundred to several thousand cubic meters, a few mining of stone mines in more than 10,000 cubic meters, annual per capita yield of 6 m3. . Equivalent to the monthly per capita production is only 0.5 m3, lower than India. As we all know, India is also the largest producer of stone. But it's granite mines are small, no modern equipment, so stone blocks low productivity. Day per capita is only 1 m3. Finland is one of the Scandinavian countries, the largest stone exporter. Its granite mine production system is world class, the dry polishing pads annual export of granite at least 25 million metric tons, up to date mine production efficiency per 40 m3. Stone mines in South Africa is a middle level of productivity, daily per capita 8-10 m3.
① assembling high cost, which is about four times the diamond wire saws;
② operating personnel, need at least two person operation. Replacement blade more people when they co-operation;
③ sawing slow, old-fashioned frame saws cutting speed is only 2cm / h. New framework for cutting speed but also 3.5-3.8 cm / h. While diamond wire saw cutting speeds of up to 20cm / h, may be increased to 30cm / h;
④ Frame Sawing sheet rough surface, flatness is also poor, so polished low speed, as 100cm/min, while Diamond Wire Sawing sheet surface is smooth, polished speeds of up to 160 cm / min , thus reducing the grinding and polishing process time;
⑤ energy consumption and material consumption is higher;
⑥ scrap disposal and mortar workplace dust causing serious environmental pollution.
