Silicon carbide (SiC) is used broadly and there are extensive applications in abrasive, chemical industry, metallurgy, high-grade refractory materials, advanced ceramics, and etc. For different field, requirements for the grain size of silicon carbide are different, which needs crushing, acid and alkali wash, magnetic separation and screening or water separation and a series of processes to make products with various grain sizes to meet the needs of the field. Among them sand making machines are good for crushing and processing silicon carbide. Sand maker is suitable for crushing and shaping soft, hard and harder material, and widely used in all kinds of ores, cement, refractory material, aluminum every soil clinker, emery, glass raw materials, construction sand, stone and various metallurgical slag, especially for silicon carbide, emery, sintering bauxite, hard sand, very hard and abrasive resistant material, there are higher efficiency and yield than other crushers.

With the extensive use of silicon carbide, it becomes the engineering processing material for solar energy industry, semiconductor industry and piezoelectric crystal industry. Along with the exhaustion of traditional minerals energy, solar cells as a representative of the photovoltaic industry develop rapidly. According to the Development Plan for New Energy Industry, in 2020 renewable energy consumption share of primary energy in proportion will achieve 15%, and photovoltaic industry will develop steadily. Silicon carbide is the upstream link of photovoltaic industry chain -- the process of crystal wafer-special material. Stimulated by photovoltaic industry, silicon carbide industry obtains some chances for expansion of downstream demands through the improvement of product structure.

Following the innovations on equipment technology of sand makers, silicon carbide has its own broad functions which strengthen the development of new application and new market for silicon carbide. And there is mutual promotion between the application of silicon carbide and development of sand maker. The wide use of silicon carbide requires the technological promotion of sand making equipment so that it can realize its own application value. So the broad application of silicon carbide promotes the development of sand makers.
