I. Project Background: The Extreme Challenge of Building a Plant in the Mountains
This project is located in a mountainous quarry in Lushan County, Henan Province. The client faced two core demands: first, the finished product must meet the stringent requirements of "high-quality manufactured sand" for surrounding highways, railways, and key new urban construction projects; second, the project is built on a mountainside with a large elevation difference, limiting the site and making traditional flat-site construction solutions impossible. Faced with the dual challenges of complex terrain and high standards, the Zhengzhou Meishuo team conducted in-depth on-site surveys and tailored a 250t/h tiered full-scale sand making solution.
II. Meishuo Solution: Leveraging the Mountainous Landscape, a Seamless Five-Stage Process
For the hillside terrace terrain, Meishuo engineers cleverly adopted a tiered layout that "utilizes the terrain and flows with the flow," allowing materials to flow smoothly from top to bottom. This not only significantly reduced civil engineering leveling costs but also minimized energy consumption from belt conveyors.
The entire line employs a five-stage closed-loop circulation process: "jaw crusher for coarse crushing + single-cylinder cone crusher for medium crushing + vertical shaft impact crushing for shaping and sand making + wheel washing + dewatering screen":
1. Stable Start: Raw materials are evenly fed into the PE750 jaw crusher via a GZG1245 vibrating feeder配套 with a large silo, completing efficient coarse crushing.
2. High-efficiency medium crushing: Coarse crushed material enters the CS430S2 single-cylinder hydraulic cone crusher (CSS discharge port precisely locked at 38mm), and the layered crushing principle significantly reduces the content of needle-like and flaky particles.
3. Stone-on-stone shaping: The core process is handled by the VSI1150 vertical shaft impact crusher, which performs deep secondary shaping and full sand making on the material, producing high-quality sand with continuous gradation and rounded particle shape.
4. Precision screening and washing: After the mixed material is efficiently classified by a 3075 vibrating screen, qualified material enters the XS3024 wheel sand washer combined with a dewatering screen to powerfully remove stone powder impurities and reduce moisture content.
III. Core Equipment: Every bit of power is converted into efficiency
●PE750 Jaw Crusher: Designed specifically for hard/medium-hard ores, its deep-cavity crushing is the "stabilizing force" ensuring a stable production capacity of 250t/h.
●CS430S2 Single-Cylinder Cone Crusher: A highly efficient fine crusher, producing near-cubic particles, directly reducing the burden on downstream shaping processes and lowering overall line wear costs.
●VSI1150 Vertical Shaft Impact Crusher: The soul of this "all-in-one sand making" production line. The produced manufactured sand has extremely low powder content, perfectly meeting the standards for high-grade concrete sand.
●XS3024 Sand Washing and Dewatering Unit: Washing out high-value aggregates! Reducing moisture content to a level suitable for direct stockpiling greatly improves the transportation and construction performance of the finished sand.
IV. Customer Benefits: A True "Turnkey" Project
● Increased Aggregate Value: All materials are processed by the VSI1150 impact crusher, resulting in finished sand quality far exceeding ordinary market standards, directly securing high-profit highway infrastructure orders.
● Drastically Reduced Operating Costs: The stepped layout saves approximately 15% on conveying energy consumption; the closed-loop circulation design minimizes equipment failure rates, ensuring a continuous and stable output of 250t/h capacity. ● Easy and Hassle-Free Plant Construction: From the initial process design, equipment selection and manufacturing to the later on-site installation and commissioning, everything is handled independently by Zhengzhou Meishuo. Customers only need to state their requirements to have a high-yield production line ready to use out of the box.
V. Conclusion The Lushan 250t/h full sand making project is another masterpiece delivered by Zhengzhou Meishuo in complex mountainous terrain. We not only provide robust crushing and screening equipment, but also deliver high-capacity, high-quality, and high-return overall solutions.
