Case Study: Low-Value Waste Shaping and Sand Making Project in Jilin Province, Northeast China
—VSI1150 Vertical Shaft Impact Crusher + 2YK2160 Vibrating Screen Supports Jitong Expressway Construction
I. Project Overview
In 2022, a shaping and sand making production line, focusing on the "high-value utilization of low-value waste," officially commenced operation in Jilin Province, Northeast China, serving the Jitong Expressway construction project.
The project's raw material consisted of locally accumulated low-value waste with a particle size below 15mm, purchased at only 15 yuan/ton. After processing using the shaping and sand making process, the finished manufactured sand was supplied to the Jitong Expressway construction team at 80 yuan/ton, resulting in a 65 yuan/ton increase in value, representing a more than five-fold increase.
From equipment arrival to official commissioning, the entire installation cycle took only 10 days, saving valuable time for the expressway project to start on schedule.
II. Core Equipment Configuration
This project uses a VSI1150 vertical shaft impact crusher as the main unit, complemented by a 2YK2160 vibrating screen and several belt conveyors, forming a compact, continuously operating shaping and sand-making production line.
The VSI1150 vertical shaft impact crusher adopts the "stone-on-stone" crushing principle and is specifically designed for shaping fine particles smaller than 15mm. It effectively improves the particle shape of the finished product, reduces the content of needle-like and flaky particles, and makes the gradation more continuous and rounded. The discharge head is made of wear-resistant material, suitable for long-term continuous operation of high-hardness materials.
The 2YK2160 vibrating screen adopts a double-layer screening structure, completing the grading of multiple specifications of finished products in one pass. It has high screening efficiency, and its processing capacity is perfectly matched with the vertical shaft crusher, effectively controlling the powder content of the finished product to meet the standards for sand used in highway construction.
The conveyor system consists of multiple belt conveyors connected in series, realizing a closed-loop operation of the entire process from "raw material feeding—crushing—screening—finished product warehousing." The overall layout is compact, occupies little space, and facilitates rapid relocation.
III. Project Highlights
1. Low-Value Raw Materials, High-Value Output: Processing waste materials costing 15 yuan/ton into highway construction sand costing 80 yuan/ton yields a gross profit of approximately 55-60 yuan/ton, truly realizing "turning waste into treasure" and aligning with national green mining and circular economy policies.
2. Rapid Production in 10 Days: The modular design allows for the completion of equipment installation, commissioning, and trial operation within 10 days, demonstrating strong project execution capabilities and providing clients with more production window time.
3. Adaptable to the Frigid Climate of Northeast China: The entire equipment operates stably in the low-temperature winter environment of Jilin Province. The steel structure platform, conveyors, and electrical systems have all undergone anti-freezing treatment to ensure continuous production during winter.
4. Excellent Finished Product Quality: After being shaped by the VSI1150 vertical shaft impact crusher, the finished sand particles are rounded and have a reasonable gradation, fully meeting the requirements for sand used in highway subgrade, base course, and some structural layers, gaining high recognition from the construction party.
IV. Economic Benefits Based on conventional operating conditions, the raw material cost is 15 yuan/ton, the processing cost (electricity, labor, and consumable parts) is approximately 8-12 yuan/ton, the finished product selling price is 80 yuan/ton, and the gross profit per ton is approximately 55-60 yuan. If the daily processing volume is 500-800 tons, the project is expected to generate annual revenue in the tens of millions of yuan, and the investment can be recovered within several months under conventional operating conditions.
V. Customer Value
Resource Utilization: Solves the long-term accumulation problem of waste materials smaller than 15mm in the local area, in line with environmental protection and circular economy policies;
Stable Supply: Provides a continuous and stable source of high-quality manufactured sand for the Jitong Expressway project, ensuring project progress;
Rapid Return on Investment: High gross profit per ton, short investment recovery period;
High Replicability: This model is applicable to various infrastructure scenarios nationwide, including expressways, railways, and new urban construction.
VI. Conclusion
This project is a typical demonstration of the high-value utilization of low-value waste. The high-efficiency combination of VSI1150 vertical shaft impact crusher and 2YK2160 vibrating screen, with its core performance of "short construction period, low cost and high output", has been operating stably in the harsh climate of Northeast China, creating significant economic and social benefits for customers and providing a successful model for similar projects.
