Along with the rapid development of domestic mining machinery and equipment industry, in order to keep up with the pace of the trend of the system ore milling equipment times, each big system sand vendors constantly generated new technology based on the introduction of sand processing equipment. The sand processing technology is more advanced, and a new type ore milling equipment or equipment with high efficiency and energy saving sets gravel and plastic for an organic whole, and is commonly used in artificial sand aggregate producing and this sand process equipment promoted the sand technology and infrastructure development. This equipment is welcomed by customers on a wide range after its introducing into the market, so the new ore milling equipment equipment is very popular in sand production field. Application field of sand making machine is very wide, commonly used in construction sites, regions such as sand, sand production lines, correspondingly plays a key role in the cement production line. Strong sand processing equipment is often met in highway, high-speed rail, Metro, large engineering construction project. Sand processing machine equipment in core equipment of whole article line in artificial sand production line, can fine crush hard river pebble, granite, limestone and other material into gravel aggregate meet building sand grain degrees requirements, and keep stones material original characteristics of strong anti-pressure, wear corrosion, etc., which can reduce cost while improve production, guarantee smooth development of infrastructure and also thrive the mining machinery industry development. So ore milling equipment plays a very important role in sand production line.
