Under the background of rapid economic development and transformation to high-quality development, the sand and gravel aggregate industry faces important opportunities and challenges. Actively responding to industrial restructuring will help achieve scale, low carbonization, environmental protection and sustainable development of the industry. However, under the changing raw materials and market environment, some newly built sand and gravel aggregate production lines failed to achieve the expected goals and a series of problems occurred. This article will analyze these problems and propose corresponding improvement countermeasures to promote the high-quality development of the industry.

Sand and gravel aggregate equipment consultation

1. Capacity and variety issues and countermeasures

With the growth of my country's economy, the market demand for sand and gravel aggregates continues to increase, and the types and performance requirements of finished products in various regions are also different. The construction standards of new production lines should be closely combined with market environment and resource conditions, and product types and annual output should be reasonably planned. The annual output of the production line is subject to the scale and equipment performance. The market environment and ore characteristics must be fully considered to avoid performance overflow or insufficient. Selecting suitable equipment and ensuring the efficient operation of various equipment will be the key to improving the efficiency of the production line.

2. Equipment selection issues and countermeasures

Equipment selection directly affects the quality and capacity of the production line. Reasonable selection should be made according to the physical properties of the local mining area to avoid affecting production efficiency due to blind pursuit of cost savings. It is recommended to hire a professional geological exploration agency to conduct on-site surveys to ensure that the equipment selection meets actual needs and reserve a certain amount of expansion space to adapt to future development.

3. Material warehouse and silo problems and countermeasures

The material warehouse is an important part of the sand and gravel aggregate production line. Climate factors may cause stone powder to be damp and difficult to discharge. To solve this problem, air cannons can be installed to keep the stone powder in the warehouse loose. The scale of the material warehouse should be controlled during design to avoid excessive moisture affecting production. At the same time, the discharge port structure of the coarse crushing feed silo should be improved to reduce dead corners and improve the smoothness of material discharge.

4. Material transfer drop problem and countermeasures

There is a problem of excessive drop during material transfer, which may cause equipment damage. The buffer roller can be replaced with a buffer material bed to optimize the discharge chute structure and reduce impact. At the same time, the chute form of the vibrating screen should be reasonably adjusted during design to reduce wear on the screen plate.

Conclusion

Sand and gravel aggregates are important raw materials for infrastructure construction in my country. In the context of the development of the new era, the industry should transform towards large-scale, low-carbon, environmentally friendly and high-quality development. By carefully analyzing the problems of the new production line and formulating reasonable improvement measures, the production capacity and quality of the sand and gravel aggregate production line can be effectively improved, which will help the sustainable development of the industry.
