How much does a river pebble sand production line cost? What are the complete sets of equipment?

1. Composition of complete sets of equipment

The river pebble sand production line usually adopts a three-stage crushing process, and the core equipment includes the following seven categories:

Coarse crushing equipment: The jaw crusher is responsible for primary crushing and processes large pieces of river pebble raw materials. Its extrusion crushing principle can adapt to high-hardness materials.

Medium crushing equipment: The hydraulic cone crusher completes the secondary crushing, and uses laminated crushing technology to improve efficiency and reduce wear, especially suitable for river pebbles with high silicon content.

Sand making equipment: The impact sand making machine is the core equipment. It uses the principle of stone hitting stone or stone hitting iron to shape the sand. The finished product has uniform particle shape and controllable powder content.

Screening equipment: The vibrating screen is used for graded screening to separate sand and gravel aggregates of different specifications.

Sand washing equipment (optional): The bucket sand washer can remove impurities on the surface of sand particles and improve the cleanliness of the finished product.

Auxiliary equipment: Including feeders, belt conveyors and intelligent control systems to ensure continuous material transmission and automated production.

Dust removal device: used to reduce dust pollution and meet environmental protection requirements.

2. Production line cost analysis

The cost of a 500-ton pebble sand production line is affected by the configuration plan and regional differences, and is divided into the following three levels:

Basic configuration (US$200,000-300,000): includes jaw crusher, cone crusher, sand making machine and basic screening and conveying equipment, suitable for small and medium-sized projects with low requirements for finished products.

Mid-range configuration (US$300,000-400,000): Add sand washing machine, high-efficiency vibrating screen and semi-automatic control system, with better finished product quality and stable production capacity.

High-end configuration (US$400,000-500,000): Adopts fully automated control system, multi-stage dust removal equipment and wear-resistant material components, suitable for long-term large-scale production, with lower maintenance costs.

3. Key factors affecting price

Equipment selection: The life of wear parts of cone crusher and impact sand making machine directly affects the maintenance frequency. High-quality equipment can reduce long-term operating costs by more than 30%.

Model combination: Multiple sand making machines in parallel or adding pre-screening links can increase production capacity, but the equipment purchase cost increases by about 15%-25%.

Energy consumption and labor: Fully automatic production lines can reduce labor demand by 60%, but electricity consumption accounts for 20%-30% of the total cost.

Regional differences: Due to strict environmental regulations in the North American and European markets, equipment prices are about 10%-15% higher than those in the Asian market.

4. Investment advice

Prioritize the three-stage crushing (jaw crusher + cone crusher + sand making machine) solution, which has a comprehensive crushing efficiency 40% higher than that of the two-stage crushing, and the replacement cycle of wear-resistant parts is extended by 50%. In the initial investment, equipment purchase accounts for about 75%, and it is recommended to reserve 15%-20% of the budget for installation and commissioning and environmental protection facilities. For river pebbles with high silicon content, it is recommended to use hydraulic cone crushers and deep-cavity sand making machines, which can reduce unit energy consumption by 0.3-0.5 US dollars/ton.
