In recent years, more and more roads are built in the village, rows of bullet trains moves across the country ...... The infrastructure construction of roads, high-speed rails and highways are put onto the schedule. Aggregate demand is increasing year by year, and the product quality requirements are also increasing. Traditional sand makers are unable to meet the industrial needs. The upgrading of sand making machines has become an inevitable trend of the times.

The upgrading of sand making machine is mainly reflected in the following aspects. First of all, improve the quality of sand making machines, and prolong the service life of the equipment. Since the traditional sand making products are of poor quality, problems are often occurred in the course of application, which seriously affects the producing efficiency. It is necessary to monitor the equipment quality with an intensified force. Secondly, we must avoid the homogenization of impact crushers. For Chinese sand making machine relies mainly on imitating foreign equipment, and at the same time each domestic manufacturers also make cross-references, the equipment is seriously homogenized. We must increase innovations on our equipment, creating our own sand products. Finally, the development of sand making machines should be guided towards the diversification direction to adapt to the developing changes in our country.

Today, the national economy developes at a rapid speed. Each industries are all competing with a fierce competition. Sand making industry is no exception. To have a foothold in the impact crusher industry, we must increase our investment on the R&D of the equipment, promoting the upgrading of equipment.
