River stone crushing plants are widely used to produce manufactured sand for construction projects.
However, many investors make mistakes when selecting river stone crushers. For example, using hammer crushers to process river stone often leads to excessive wear of spare parts and high maintenance costs.
For this reason, most modern river stone crushing plants adopt a three-stage crushing process, which improves production efficiency while reducing operating costs.
River stone crushing plant process: three-stage crushing
This is the three-stage crushing process used in the river stone crushing plant designed by FTM Machinery:
Primary crushing → Secondary crushing → Sand making and shaping
These river stone crusher configurations combine laminated crushing and rock-on-rock shaping, ensuring high capacity and low wear costs.
Primary crushing – European type jaw crusher Get a quote
The deep chamber design can handle feed sizes up to 1,000 mm. Compression crushing reduces the wear of spare parts, and the jaw plate life is twice that of standard models.
The European type jaw crusher can quickly crush river stone to below 300 mm, reducing the pressure on the next process. The capacity of a single machine can reach up to 1,280 tons per hour.
Secondary crushing – Hydraulic cone crusher Get a quote
The hydraulic cone crusher uses a laminated crushing principle designed for high-hardness materials. The wear parts last 5 times longer than those of impact crushers, and the operating noise is as low as 85 dB.
It reduces the aggregate size to below 40 mm. Compared with impact crushers, the output rate increases by 15% while energy consumption decreases by 30%.
Sand making and shaping – VSI crusher Get a quote
The VSI crusher processes 4–50 mm aggregate into 0–5 mm manufactured sand, and it can switch between sand making mode and shaping mode to meet different needs.
The crusher's "rock-on-rock" technology can produce sand with more than 90% cubic particles and less than 8% needle-shaped particles, fully meeting high-speed railway construction standards.
The wear-resistant roller sleeve has a service life of more than 2 years, which is 10 times longer than that of hammer sand makers.
River stone crushing plant project cases
1. Small river stone sand plant in Philippines
A customer from the Philippines invested $120,000 to build a small river stone sand plant. He chose a cost-effective configuration: two European jaw crushers, one VSI sand making machine, and one sand washing machine.
With these machines, the plant produces about 800 tons of high-quality manufactured sand per day. The project achieved a fast return on investment, recovering the full investment in just 10 months. Since then, the plant has maintained an annual profit of more than $100,000.
2. Medium-scale river stone crushing plant in Indonesia
Our customer in Indonesia invested $200,000 to expand his sand and aggregate production capacity. The plant chose a configuration of two jaw crushers, two VSI crushers, and one 4YK vibrating screen.
This river stone plant now produces 1,600 tons per day. The high-quality sand helped the company win valuable supply orders for a local high-speed railway project. This investment has made the factory one of the most competitive aggregate suppliers in the regional market.
