River pebbles feature high hardness, strong wear resistance, low impurity content and pure texture, making them an ideal raw material for producing high-quality manufactured sand.
Do you know how to achieve high profits from river pebble sand making? The answer lies in having a mature production process and a scientifically optimized machinery configuration.
The complete river pebble sand making production process includes: raw river pebbles → primary coarse crushing → secondary fine crushing → sand making → sand screening → sand washing and drying.
Each stage is closely interlinked, and every step of the process and the choice of equipment affect the final quality of the river pebble sand.
River pebble coarse crushing: reduce raw particle size
Jaw crushers are usually the first choice for river pebble primary crushing. Its feed size is below 1200 mm, and the capacity for crushing stones of 50 t/h, 100 t/h, 200 t/h and 300 t/h.
- Low-cost and easy-to-maintain: It has a simple structure. Wear-resistant parts can be replaced easily, which greatly cuts later operation costs.
- Excellent crushing performance: Large hard river pebbles can be fed directly into the machine. With advanced technology, this single machine can save 15%–30% energy.
River pebble medium crushing: optimize aggregate gradation
As the core equipment for secondary crushing of river pebbles, the cone crusher easily handles hard, highly abrasive river pebbles, producing crushed stone with uniform particle sizes and lays a solid foundation for the downstream sand making stage.
The output size of the cone crusher is 3–64 mm, and the output is suitable for medium crushing of stone at 100 t/h, 150 t/h, 250 t/h and 350 t/h.
- Adjustable discharge size: It can change output particle size freely and provide steady raw material for the next sand making step.
- Stable operation: It has overload protection, which reduces the risk of material jamming. The machine also can process plenty of river pebbles for a long time.
Choosing river pebble sand crusher: high-quality manufactured sand
The river pebbles sand making stage is vital for producing high‑quality manufactured sand. Choosing the right river pebble sand making machine is especially critical. FTM Machinery offers three sand making crushers. Find out which one fits your project.
1. VSI sand making machine
The VSI machine is the classic river pebble sand making machine. It uses a proven double‑crushing principle and is built for hard, abrasive stone materials.
Capacity: 40–650 t/h
Feed size: Hard materials <45 mm, soft materials <50 mm
Output size: 0–5 mm
- Superior product quality: It delivers excellent crushing and shaping results, producing manufactured sand with rounded, well-formed particles and a very low content of needle-like or flaky fragments.
- Outstanding cost-performance ratio: The impeller is made of high-chromium steel and the main shaft of high-quality alloy. This durability eliminates the need for frequent part replacements, keeping overall operating costs under control.
Our best-selling VSI sand maker machine models include:
| Model | Capacity (t/h) | Max. feeding size (mm) | Output particle size (mm) | ||
| Feed both at center and sides | Feed at center | Soft materials | Hard materials | ||
| VSI 8518 | 140–260 | 70–130 | ≤ 40 | ≤ 35 | 0–5 |
| VSI 1145 | 350–610 | 180–355 | ≤ 50 | ≤ 45 | 0–5 |
2. Ultrafine sand making machine
The ultrafine grinding sand making machine is a special fine sand making crusher. It works well for high‑precision stone processing and makes high‑quality fine sand.
- Superior fine sand capacity: Optimized for 0–3 mm sand production, it greatly boosts the output ratio of ultrafine sand and suits large scale fine sand production.
- Excellent particle shape: The integration of crushing, shaping, and grinding effectively optimizes the of river pebbles shapes and yields large quantities of high-quality, cubical particles.
Our best-selling ultrafine sand making machine models include:
| Model | Throughput（t/h） | Feeding Size（mm） | Output particle size（mm） |
| FGM1113 | 35–43 | ≤ 55 | 0–3 |
| FGM2215 | 100–119 | ≤ 55 | 0–3 |
3. Mobile sand making machine
The mobile sand maker machine combines feeding, sand making, screening and conveying together, which gets rid of site limits from traditional fixed sand making lines. So it is the top choice for movable river pebbles sand making projects.
- Flexible and convenient relocation: Featuring an integrated modular design, the unit requires no civil engineering work and can be relocated to different sites as needed.
- Production cost savings: It supports the on-site sourcing and processing of river pebbles, eliminating the need for long-distance transport of raw rock and finished sand, thereby effectively reducing overall project operating costs.
Our best-selling mobile sand making machine models include:
| Model | Throughput（t/h） | Feeding Size（mm） | Output particle size（mm） |
| WT0818 | 60–283 | ＜ 30 | 0–5 |
| WT0926 | 85–380 | ＜ 40 | 0–5 |
River pebble sands screening: control particle grading
Processed river pebbles sand goes into the vibrating screen. The screen separates pebbles sand into finished products of different sizes, getting well‑classified final materials.
- High screening efficiency: The 18° inclined screen deck improves screening efficiency. The eccentric exciter provides strong power for stable classification.
- Easy maintenance & longer service life: Self‑lubrication extends oil‑change intervals and key parts are protected by wear-resistant rubber.
Sand washing & drying: boost sand purity
If you have strict requirements for sand powder content, you can add sand washing machines and sand dryers after screening to effectively remove dust from aggregates and ensure finished sand meets quality standards.
The advantages of sand washing machine:
- Low-cost & reliable operation: It has a simple structure for easy maintenance. Spare-part replacement costs are low, and the machine runs stably with long service life.
- Great washing performance & wide adaptability: It handles large-volume sand, delivers clean results with little material loss, and produces high-quality sand in various working sites.
Sand dryer offers:
- Fast dewatering speed: It quickly removes surface moisture from washed river pebble sand.
- Uniform drying quality: The sand gets even moisture content after drying, so final sand meets quality requirements.
