Shibang's 500-600 tons per hour limestone crushing and sand making production line utilizes scientific processes and high-yield, low-energy equipment to achieve full crushed stone and optimally graded manufactured sand, while reducing energy consumption by 500 kW/h and meeting the high standards required for highway surface materials.

Limestone is a common, high-quality sand-making raw material, making the efficiency and quality of its crushing and sand-making production line crucial. Shibang's 500-600 tons per hour limestone crushing and sand-making production line offers superior process flow and equipment configuration.

Process Flow: Meticulous and Orderly, Ensuring Quality

The production line's process flow is scientifically and rationally designed, with meticulous planning at every step, from raw material acquisition to finished product output. First, limestone raw material is obtained through mountain blasting and fed into the F5X1360(S) feeder for pre-screening. The feeder's built-in screen efficiently removes debris, achieving initial purification of the raw material. After screening, small materials are directly fed into the transfer silo of the impact crusher, while larger materials are first crushed by a jaw crusher before entering the transfer silo. This combination of pre-screening and initial crushing lays the foundation for subsequent efficient production.

The materials in the transfer silo are simultaneously fed into two PFW1318Ш European-style hydraulic three-chamber impact crushers for crushing. The impact crusher's unique operating principle crushes materials into a relatively uniform particle size. The crushed materials are then screened by the new S5X2760 vibrating screen, while larger materials return to the impact crusher for further crushing, forming a closed-loop system to ensure thorough material crushing. Stone powders in sizes of 0, 3, and 6 mm are screened out and can be used as raw materials for other applications. The remaining finished products, in sizes ranging from 6 to 31.5 mm, are fed into the VSI6X1263 impact crusher for shaping and sand production. The impact crusher's shaping effect results in a more uniform particle shape, significantly improving the quality of the manufactured sand. Finally, the crushed material is sequentially screened by two S5ZX2760 vibrating screens, resulting in six finished product sizes: 0, 3, 6, 11, 19, 26.5, and 31.5 mm, meeting the diverse particle size requirements of different customers.

Equipment Configuration Advantages: High Output, Low Energy Consumption, Stable and Reliable

Rational Layout, High Quality: The entire production line is compact and rationally arranged, significantly reducing the number of equipment and conveyors, making the production process simpler and more streamlined. This design not only saves space but also reduces equipment maintenance costs. Furthermore, through the configuration of specialized equipment, the production line ensures the quality of both crushed stone and manufactured sand. The crushed stone after shaping has a full shape and low flake content, while the manufactured sand produced by the sand making machine has a uniform particle size and a well-graded structure, fully meeting the high standards and requirements for highway surface materials and bridge materials.

High Output, Low Energy Consumption, and Reduced Costs: This production line utilizes a series of high-output, low-energy products, including a European-style hydraulic jaw crusher, a European-style hydraulic three-chamber impact crusher, a VSI6X series impact crusher, and an S5X series high-efficiency vibrating screen. Compared to competitors in the same industry, this line reduces energy consumption by at least 500kW per hour at the same output, significantly lowering operating costs and creating higher economic benefits for the company.

"Three-stage Crushing" Reduces Wear: This production line meets the customer's required "three-stage crushing" concept. By rationally dividing the crushing stages, wear on all main equipment is reduced. This design ensures more stable operation, significantly reduces late-stage failure rates, reduces equipment downtime and maintenance, and improves overall production line efficiency.

Core Equipment: Strength and Responsibility, Forging Quality

This production line is equipped with core equipment such as a PEW jaw crusher, a PFW impact crusher, and a VSI6X vertical shaft impact crusher. The PEW jaw crusher has the advantages of a large crushing ratio, high output, and stable operation. The PFW impact crusher adopts advanced hydraulic technology, with high crushing efficiency and good particle shape. The VSI6X vertical shaft impact crusher integrates multiple crushing modes and can effectively realize material shaping and sand making. The coordinated operation of these core equipment provides a strong guarantee for the efficient operation of the production line.
