At a time when the sand and gravel industry is booming, Liming Heavy Industry has created a series of efficient, intelligent and environmentally friendly machine-made sand production lines with its profound technical background and outstanding innovation capabilities, setting a new benchmark for the industry.

The machine-made sand production line of Liming Heavy Industry is scientifically and rationally designed, taking into full account the needs and actual application scenarios of different customers. Its production line can be carefully designed according to the on-site survey or the actual requirements of customers, with significant characteristics such as large processing capacity, low wear and low operating costs. Whether it is hydropower, building materials industry, or highways, urban construction and other fields, Liming Heavy Industry's machine-made sand production line can show strong adaptability and high efficiency.

The core equipment configuration of this production line is first-class. As the key equipment in the coarse crushing link, the jaw crusher adopts high-strength wear-resistant materials and is equipped with an optimized crushing cavity. It can quickly crush large pieces of material into suitable sizes with strong bite force, laying a solid foundation for the subsequent crushing link. The cone crusher or impact crusher undertakes the task of medium and fine crushing. According to the characteristics of different materials, the materials are further crushed into uniform particles through precise discharge port adjustment and intelligent control system. The vertical shaft impact crusher (sand making machine) is the "star equipment" of the production line. It adopts advanced crushing principles, accelerates the material to be thrown out through the high-speed rotating impeller, realizes the mutual impact crushing between the materials, and produces machine-made sand with uniform particle size, good particle shape and reasonable gradation, which fully meets the national construction sand standards.

In a river pebble sand making production line project in Longnan, Gansu, Liming Heavy Industry's machine-made sand production line shines. The project processes 800 cubic meters of river pebbles per day, and the main equipment includes 2 PEW250x1000 European version jaw crushers and VSI9526 sand making machines. The PEW European version jaw crusher is used for coarse crushing, and the VSI9526 sand making machine performs more detailed shaping processing on the coarsely crushed stones, making the finished sand and gravel particles more uniform and the gradation more reasonable. The entire production line operates stably and has a large output, providing high-quality stones for local infrastructure construction.

In addition, Liming Heavy Industry's machine-made sand production line is also equipped with complete environmental protection equipment, such as dust removal systems, to effectively control dust and noise pollution and achieve green production. At the same time, the production line has a high degree of automation, requiring less than 3 production workers per shift, which greatly reduces labor costs and improves production efficiency.
