An example of technological transformation in the field of sand and gravel construction materials production at Shibang: how to transform an inefficient sand and gravel crushing line?

The problems are related to the incorrect selection of crushing and screening equipment, outdated equipment leading to high maintenance costs, and an outdated process flow, resulting in unsatisfactory aggregate particle size distribution and low market competitiveness. Below are several examples of inefficient sand and gravel production lines that have been upgraded with Shibang solutions.

Consulting on sand and gravel production line modernization

Ningbo VU Tower sand crushing plant modernization project:

Previously, the customer used purchased sand with high moisture content, unstable quality, and high cost. Choosing the Shibang VU Tower dry sand production system instead of purchased sand not only saved on drying costs but also significantly improved the quality of the sand used at the concrete plant. After the upgrade, the resulting sand has an excellent particle size distribution, which greatly pleases the client.

Zhejiang Jiaotong Mining tuff crushing and sand production equipment modernization project: The client required modernization to increase sand production capacity while maintaining the quality of the finished aggregate. After evaluation, Shibang's technical staff increased the linear speed of the impact crusher by 15%, increasing sand production capacity by 10% and significantly improving the quality of the finished product, thus achieving the client's modernization goals.

The limestone/granite crushing and grinding modernization project on Chongming Island: the initial process design encountered screening problems with mesh sizes from 0 to 80 mesh during production, resulting in finished products that did not meet the customer's requirements. After a thorough on-site investigation, Shibang's technical staff made minor modifications to the process and recommended adding a classifier. After the upgrade, the efficiency of material screening and classification significantly improved, and the customer was very satisfied.
