Mining broken sand is the important aggregate that is indispensible to configure concrete aggregate and accounts for more than sixty percent of the concrete proportion. With the fast development of the infrastructure construction, building sand becomes more and more important for the quality of the engineering projects. The natural sand is decreasing day by day, so the artificial one is the best building sand that is used for replacing the natural one. It has three different specifications of coarse, medium and fine that are produced by the mining sand crushing machine crushed the large sized stone. With proper use of the stone powder in the sand, it will perfectly be suitable for the design and proportioning of the concrete and has the advantages of resisting compression and anti permeability.

According to the demand in the domestic infrastructure construction, large quantity of sand and stone materials will be invested and put into use and effectively processing and making full use of them. The stone is sent into the sand crushing machine and using three crushing methods of pressing, impacting and crushing. There are many mining crushing equipment at present such as hammer crusher and impact crusher. As for the final sand and stone aggregate, the quality and graduation can only be excellent after they reach some standard. Zhongjiao Mining Machinery researched, developed and launched and new type of mining sand crushing machine and launched high comprehensive crushing and production capacity for domestic high sand making standard.

The mining sand crushing machine is the crushing machine that has the widest application in the crushing stone and sand aggregate in the basis construction. Concrete is the most important building materials so that the quality of the sand and stone aggregate. The artificial one is the most advanced crushing equipment in the crushing technology field. In order to guarantee the quality of these materials, adopting the technology of screening and washing and ore dressing will improve the quality of them and improve the economic benefits of the crushing and grinding machines.
