Development of Mechanism Sand Industry Enter Fast Lane

Since the 1990s, many places in China where is no natural sand began the study of the application of the mechanism sand. Then a lot of mechanism sand production lines were established. Since there are no entries for the mechanism sand in the national standard, there are still a lot of restrictions and resistance in the engineering use. After entering the new century, the implementation of new national gravel and sand standards provides the theoretical basis for the production and application of the mechanisms sand. Now the mechanism sand gradually embarks on the road of rapid development. Mechanisms sand is suitable for the policies of the country and it has a lot of advantages. For example, the mechanism sand can compensate for inadequate supply of the coarse sand and medium sand in the natural sand resources. The grade of the sand can be manually deployed and the composition of the sand can be artificially controlled. You can take full advantage of the various kinds of abandoned tailings or waste rock to achieve the purpose of the comprehensive utilization. The shortage of the sand resources opens a broad space for the promotion, application and the development of the mechanism sand.
In recent years, the commercial concrete mixing station with high degree of mechanization has been widely used. These enterprises have strength to do a lot of matching researches. In China, the mature application of the mechanism sand is in the large-scale water conservancy project. The supporting engineering construction aggregates production systems and experience in the use of the mechanism of sand are very perfect and mature.
 The gravel industry is a kind of resource industry. After experiencing the rapid development, the natural sand is also facing the reduction of resources and depletion problem like other resource products. Product quality of the natural sand decreases significantly. The resource depletion and the poor quality or specifications of the natural sand can not meet the requirements of the project and particularly can not meet the needs of the performance of the high-quality concrete.
In order to maintain the sustainable development of the sand and gravel industry, we should vigorously develop the mechanisms sand in response to the decline in quality and the reduction or depletion of natural medium coarse sand. We should also make full use of the tailings or waste rock and process them to replace the research and application of the natural sand. We should solve the problem of comprehensive utilization of resources in order to promote environmental protection.
The sand making machine produced by Henan Hongxing Mining Machinery is the ideal equipment for producing the mechanism sand. We should truly do well the work of comprehensive utilization of resources to guide the scientific development trend of the sand and gravel industry in China.
