Shibang Group's 500 tons/hour green sand and gravel production line in Shandong adopts intelligent crushing and screening technology to achieve efficient conversion of limestone to fine aggregates. The fully enclosed design reduces dust and noise by 60%, the recycling rate of water resources reaches 100%, and the added value of machine-made sand products exceeds 20%. It supplies high-quality building materials for the infrastructure in the Yangtze River Delta and sets a benchmark for the integrated demonstration of "crushing-screening-environmental protection" in green mines.

Under the background of vigorously promoting the construction of ecological civilization, Shibang Group has successfully built a 500-ton-per-hour fine sand and gravel aggregate production line in Shandong with its rich industry experience and advanced technological advantages. This project not only achieves efficient resource utilization, but also sets a new benchmark for the development of the green building materials industry.

1. Scientific configuration, precise matching

The production line adopts the advanced configuration plan of "jaw crusher + impact crusher + impact crusher", equipped with 4 core equipment such as vibrating screens and sand washers. According to the characteristics of limestone raw materials (feed ≤800mm), efficient crushing is achieved through scientific layout to ensure stable and reliable quality of finished products. The main products include 4-10-23mm standard stone and 0-4mm fine machine-made sand, which fully meet the high standard requirements of the southern market and local key projects.

2. Process innovation, excellent quality

Intelligent screening and washing system: The intelligent screening and washing process is adopted to effectively control the powder and mud content of the finished aggregate, ensuring the high cleanliness and quality of the machine-made sand and gravel.

Wet production technology innovation: Through a perfect sewage treatment system, water resources are recycled to create good economic and environmental benefits.

Fully enclosed environmental protection design: The fully enclosed warehouse structure is adopted to significantly reduce dust and noise pollution, providing a model for the construction of modern green mines.

3. Green environmental protection, circular development

Water resource management: Equipped with advanced sewage treatment equipment such as filter presses, the whole process of production wastewater purification and recycling is realized, and the water use efficiency is significantly improved.

Intelligent logistics system: Apply smart shipping technology to achieve accurate measurement and efficient transportation, and escort the product quality throughout the process.
