Longzhong Heavy Industry Cobblestone Production Line Setup

The only two sand and gravel plants in Luoyang City have adopted equipment from Longzhong Heavy Industry. Thanks to its regional advantages, Luoyang features numerous old riverbeds. These conditions are essential prerequisites for the operation of a sand and gravel plant.

Cobblestone is a byproduct of yellow sand mining, named for its resemblance to natural cobblestones. It is characterized by high hardness, bright and simple coloration, and the durability of natural stone against compression, wear, and corrosion, making it a frequently used green building material. Additionally, it serves as an ideal raw material for manufactured sand, widely applied in construction, decoration, landscaping, sewage treatment, and other sectors.

Cobblestone raw material sourced from ancient riverbeds contains 70% sand and gravel, resulting in low crushing costs. After crushing and washing, the sand yield is significantly higher than that of conventional raw materials, enabling customers to achieve substantial profits. Additionally, these ancient riverbed materials can undergo magnetic separation to extract gold and iron powder. The recovered gold and iron powder represent another major revenue stream for customers.

1. Cobblestone production process

The cobblestone crushing production line is similar to a standard stone production line, with differences primarily in particle size requirements. Customers can adjust these parameters according to their specific process needs.

The cobblestone crushing production line comprises a jaw crusher (coarse crushing), cone crusher (fine crushing), vibrating screen (circular vibrating screen), vibrating feeder, belt conveyor, sand washing machine, and sludge treatment equipment. By configuring the appropriate types of equipment according to specific process requirements, optimal performance can be achieved. This production line features a high degree of automation, low operating costs, high crushing efficiency, energy savings, large output capacity, minimal pollution, and easy maintenance.

2. Customer Site

The site selection for this project was strategic and well-balanced, leveraging the natural terrain to minimize initial investment. After nearly three years of operation, profitability has been maximized. The facility is not only meticulously planned, organized, and orderly but also maintains a clean and aesthetically pleasing environment. This sand and gravel plant redefines industry standards, challenging the traditional perception of such facilities as dirty or disorganized. This success reflects careful early-stage planning, optimal terrain utilization, and the engagement of professional teams. LZZG Heavy Industry boasts a specialized team with over ten years of experience, capable of designing customized production lines tailored to customer needs. We offer comprehensive one-stop services—from site selection and engineering design to equipment supply, ongoing maintenance, and after-sales support—ensuring all your operational challenges are effectively addressed.

Most sand and gravel plants are located in remote, sparsely populated mountainous areas. How can plant owners maintain full visibility of operational dynamics when they are not on-site? Longzhong Heavy Industry is advancing its Internet of Things (IoT) strategy to build intelligent factory areas. This allows you to monitor the status and output data of all equipment without leaving your office. Intelligent monitoring and data-driven production enable precise output forecasting while saving manpower and material resources, ultimately maximizing benefits.
