With the rapid development of cities, the disposal of construction waste generated from infrastructure construction or house demolition is currently a matter of great concern. At the same time, mobile crushers for processing construction waste in the crushing industry are also facing huge development opportunities.

In fact, the sand and gravel aggregates used in our country in the past were basically natural sand and gravel collected directly from rivers and mines. Years of mining have put the resources at risk of depletion. As my country's ecological civilization construction continues to advance, resource and environmental constraints and controls have become increasingly strengthened, making the contradiction between supply and demand more prominent.

As a last resort, coastal areas such as Guangdong, Fujian, Zhejiang, Jiangsu, and Hainan have begun to import large quantities of sand and gravel from countries such as Malaysia and North Korea.

Sand and gravel are basic and indispensable building materials in engineering construction. The Party Central Committee and the State Council attach great importance to the healthy and orderly development of the sand and gravel industry. In order to stabilize the sand and gravel market supply, maintain overall stable prices, and promote the healthy and orderly development of the industry, with the approval of the State Council, on March 25, fifteen departments and units including the National Development and Reform Commission jointly issued the "On Promoting the Healthy and Orderly Development of the Sand and Gravel Industry" Guidance of
