Tuff Crushing and Sand Making Project of Liulishan Mine of Zhejiang Jiao Mining

In order to cope with the market's increasing requirements for sand and gravel quality, Haixin Mining decided to carry out technical transformation of the production line. By introducing advanced equipment and improving equipment performance, the capacity of machine-made sand increased by 10%, the quality was significantly improved, meeting market demand and gaining market competitive advantage.

With the continuous improvement of the quality requirements of the terminal market of sand and gravel in Jiangsu, Zhejiang and Shanghai for finished aggregates, Haixin Mining Company keenly captured this market change, actively changed its production strategy, and proposed the need to transform and upgrade the machine-made sand production line to improve production capacity and product quality.

Project Background

In order to cope with the increasingly stringent quality requirements of the market, Haixin Mining decided to carry out technical transformation of the existing production line. Especially for tuff, a raw material with high compressive strength (average 272MPa for limestone and 155MPa for felsic porphyry), they hope to ensure the high quality of finished aggregates while increasing the capacity of machine-made sand.

Technical transformation measures

1. Introducing advanced equipment In order to meet the needs of the owner, the HPT multi-cylinder hydraulic laminated crushing cone crusher of Shibang Group was used in the fine crushing process. This equipment is efficient and stable, and can effectively process high-strength tuff in the fine crushing process.

2. Improve equipment performance After a series of technical demonstrations and optimizations, the technical staff of Shibang Group increased the linear speed of the impact crusher in the production line by 15%. This adjustment not only increased the production capacity of machine-made sand, but also significantly improved the quality of machine-made sand, including particle shape and gradation.

3. Improve comprehensive benefits Through this technical reform, the production capacity of machine-made sand increased by 10%, and the quality of machine-made sand also improved significantly. High-quality machine-made sand can better meet market demand, making Haixin Mining occupy a favorable position in the fierce market competition.

Feedback from the owner

This renovation and upgrading project not only achieved the expected capacity increase target, but also significantly improved the quality of finished aggregates, fully meeting the market demand for high-quality sand and gravel. Haixin Mining highly recognizes the technical support and equipment performance provided by Shibang Group, and looks forward to continued cooperation on more projects in the future.

Conclusion

Through this technical reform, the tuff crushing and sand making project of Liulishan Mine of Zhejiang Jiao Mining has achieved a double increase in production capacity and quality. With its advanced equipment and professional technical support, Shibang Group helps mining companies to continuously make new breakthroughs in market competition.
