Liming has built a basalt crushing and sand-making production line with an annual output of 3.4 million tons in Zhejiang. It adopts jaw crusher primary crushing, cone crusher medium and fine crushing, vertical shaft crusher sand-making shaping and vibrating screen grading technology to achieve efficient and green production. The finished aggregate has excellent particle shape and precise grading, setting a new benchmark in the industry.

In the field of hard rock crushing, basalt poses severe challenges to production equipment and process flow due to its high hardness and high wear resistance. With its profound experience in hard rock crushing and many successful project cases, Liming has successfully built a basalt crushing and sand-making production line with an annual output of 3.4 million tons in Zhejiang, and supplies high-quality aggregates to the market with advanced process flow and high-end equipment configuration.

Primary crushing of raw materials: jaw crusher starts efficient crushing

The basalt raw materials are evenly and stably fed into the jaw crusher through the feeder to start the crushing journey. As the core equipment of the primary crushing link of the production line, the jaw crusher has a strong crushing capacity. It uses the reciprocating motion of the movable jaw and the fixed jaw to forcefully squeeze and crush large pieces of basalt, crushing large-sized raw materials into smaller pieces, and providing materials of suitable particle size for subsequent crushing processes. This process not only effectively reduces the processing pressure of subsequent equipment, but also ensures the continuity and stability of the entire production process.

Medium and fine crushing: Cone crusher progressively grinds and grinds

After the primary crushing, the basalt material enters the medium and fine crushing link, and the single-cylinder hydraulic cone crusher and the multi-cylinder hydraulic cone crusher appear in turn. The single-cylinder hydraulic cone crusher achieves efficient and accurate medium crushing operations with its unique hydraulic system and optimized crushing chamber. It can flexibly adjust the size of the discharge port according to the material characteristics and production needs to ensure that the particle size of the crushed material is uniform and meets the requirements.

The multi-cylinder hydraulic cone crusher further crushes the material. Its multi-cylinder hydraulic protection system can effectively buffer the overload pressure when facing high-hardness basalt, protecting the equipment from safe and stable operation. At the same time, the advanced laminated crushing principle makes the materials squeeze and rub against each other in the crushing chamber, which not only improves the crushing efficiency, but also improves the finished product particle shape, making the aggregate particles more regular and round, laying a good foundation for the subsequent sand making process.

Fine sand making and shaping: vertical shaft impact crusher shapes high-quality sand and gravel

The materials that have been processed by medium and fine crushing enter the vertical shaft impact crusher for sand making and shaping operations. The vertical shaft impact crusher adopts the working principle of combining "stone hitting stone" and "stone hitting iron". Driven by the high-speed rotating rotor, the materials collide and rub against each other to achieve efficient sand making. At the same time, the unique shaping function can finely grind the aggregates, remove sharp edges and corners, so that the finished sand and gravel particles are excellent and the grading is reasonable, which fully meets the needs of high-quality aggregates.

Screening and grading: The vibrating screen accurately controls the particle size of the finished product

The materials after sand making and shaping are sent to the vibrating screen for screening and grading. The vibrating screen uses screens of different specifications to accurately separate the materials into finished products of various particle sizes such as 0-3mm, 3-5mm, 5-10mm, 10-15mm, and 15-26.5mm. This link strictly controls the particle size of the finished products to ensure that each batch of products meets the standard requirements. Moreover, the production line can flexibly adjust the screen specifications according to the actual market demand to achieve rapid switching of the finished product particle size, which greatly enhances the adaptability and market competitiveness of the production line.

In the entire production process, the dry treatment process avoids the use of water resources, reduces production costs, and reduces environmental pressures such as wastewater treatment. With scientific and reasonable process flow and advanced and reliable equipment configuration, the production line has achieved efficient, green, and intelligent production goals, setting a new benchmark for the basalt aggregate processing industry.
