Gravel industry is sizeable today, and gravel supplying company is densely covered all over the country, and the number increase of gravel plant has also brought a lot of problems:
First, the increase in the number of gravel plant causes great environmental pressures, and the increase in the number of gravel plant also needs more mines and quarrying area.
Second, the increase in the number of gravel plant leads to the low utilization of mining area and enormous waste of resources.
Third, the increase in the number of gravel plant causes the unreliable quality of gravel. Sometimes, some of them cannot be used, but have been applied by public relations, leaving the security risks.
These are difficulties in development of gravel industry, so the State addresses the problems in gravel industry together the control and integrating of mineral resources.
First of all, control the number of gravel mining of rock and centralize the decentralized set of resources; Secondly, encourage small business to combine with large business, to efficiently use resources, improve sand quality on the market, and deal with mining tailings. For this reason, large stone crusher finds its spring, and large stone crusher includes a number of gravel mining crushers and sand crushers. Large stone crusher is widely used in large mines, applicable to large-scale mining, with large capacity and high efficiency, and avoiding the waste of mineral resources and boosting corporate profits.
