Abstract: Sand able to start at the main or a comprehensive ban on Chinese popular river sand dug from China. In 2005, the state issued a series of prohibitions against large-scale dredging of river sand behavior, for a time, resulting in a sand source of tension, in addition to the third generation of Sand, sand than natural sand has a larger surface area, higher with sand preparation of concrete strength. Secondly, sand production can be combined with gravel production process, greatly reduce production costs mechanism sand. Finally Sand, sand beneficial utilization of mineral resources, not only to solve environmental problems and improve the utilization of natural resources. Efficient crushing machine plays an irreplaceable role as the sand core production line of broken equipment. Faced with these phenomena and problems, sand production will have a significant market opportunity, manufacturing high-quality sand and gravel in order to become a gold industry. 1, the production technology behind the current domestic impact Sand, mostly imitation, less developed, started earlier but the development of unpleasant vsi crusher, the manufacturers of similar products. While with the price advantage in the market to take advantage of the number of sales, compared with foreign advanced level is still lagging behind in terms of technical quality: Domestic Sand wearing parts (butt head, manifold, bearing plate, back plate, impeller body) life expectancy is lower than the foreign advanced products. 2, made a number of sands, but generally small scale, low management level. The sand there are many companies in various parts of China, but are generally less natural mechanisms mining more production, fewer small-scale production of large scale informal enterprises, which caused great difficulty for the management of sand industry. 3. The need to improve standards. Compared to other industries, policy and planning on the introduction of small gravel, part of the policy and the relevant provisions of the relatively backward. People on the concept of sand to cement production lighter. This restricts the production of sand in large part. Sand also known as impact crusher, Barmac US companies use the famous "stone at stone" crusher works and production technology, combined with sand production technology at home and abroad to develop out of the situation with the international advanced level stable performance, low emissions equipment, its performance in a variety of fine ore broken equipment can not be replaced, and the most effective, practical and reliable. The crusher is used in construction sand, road sand, asphalt concrete and cement concrete aggregate ideal production equipment, can be used for transportation, construction, etc; in the field and is an indispensable machine. It is suitable for crushing soft or medium hard and extremely hard materials, plastic, widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and various metallurgical slag, wide range of applications, especially for silicon carbide, silicon carbide, sintered bauxite, the US high sand hard, special hard and abrasion resistance material is higher than other types of crusher production efficiency.
