As a natural stone, pebbles are forming by millions of years of water flushing, extrusion, collision and sedimentation. Pebbles are usually smooth, but depending on how often they come into contact with the sea.

Pebbles can be found on the existing various beaches of oceans and inland areas once covered by ancient seas. When the oceans receded, landlocked countries form. Therefore, we can see the pebbles in rivers, lakes and ponds. In addition, the peebles can also form in the rivers, change never stops.

According to the location pebbles mined, it divided into beach pebbles and river pebbles, they are different in geological structure and appearance.
Beach pebble mostly smooth, round shape, and the size usually in 2-50mm, common colors are translucent white, yellow, brown, green, black.
The river pebbles are usually not as smooth as beach pebbles, owing to the gentler river current. Common colors are black, grey, green, brown, and white.


Cobblestones are widely used in public buildings, villas, courtyard buildings, paved roads, park rockeries, bonsai filling materials, garden art and other high-end buildings.

Cobblestones are high-quality materials for water purification, sewage treatment, electricity, gardening, and the like. It also a kind of raw and auxiliary materials for ceramics, precision casting, paper making, jet grinding, chemical, monocrystalline silicon, and national defense.

artificial making pebble sand are widely used in the water conservancy and hydropower, high-grade highways, highways, high-speed railways, passenger lines, bridges, airport runways, municipal engineering, high-rise buildings, sand production and stone shaping.

River pebbles crushing process

The river pebble production process can crush 0-40mm gravel raw material by vertical shaft impact crusher (sand making machine). This rock crusher is a new sand making machine, which has high crushing efficiency, convenient installation and maintenance, low running cost, excellent product granularity (more in cubes and less needle-like shape).

Applicable materials】River pebbles, cobblestone
Applications】Cement concrete, asphalt concrete and various types of stable soil materials in construction engineering, as well as road, bridge and culvert, tunnel light highway engineering.
Equipment】Feeder, cone crusher, VSI sand making machine, sand washing machine, YK series circular vibrating screen, belt conveyor, etc.

River pebble processing flow

The characteristics of the river pebble vary from place to place. When selecting the equipment, the wear resistance of the equipment should be placed first. Large particle size can refer to the crushing of granite and basalt; small particle size needs to be pre-screened to reduce production cost.

Take the river pebble below 200mm as an example:
The raw material is conveyed to the 1# vibrating screen through the vibrating feeder and belt conveyor, the material larger than 40mm enters the cone crusher, 5-40mm enters sand making machine, and the 0-5mm are directly washed.

The cone crusher reduces the large particle gravel into smaller pieces, #2 vibrating screen screened the material larger than 40mm return the cone crusher, while conveying the material less than 40mm into the sand making machine.

Same as the cone crusher crushing circuit, the sand making machine and the #3 vibrating screen separately crush and screen the material, which less than 20mm are transported to the finish product pile.

According to the cleanness of materials, it is considered to wash the 0-5mm fine sand.

pebble crushing process


This pebble sand production line has reasonable configuration, high degree of automation, low operating cost, high breaking rate, energy saving and environmental protection, large output and easy maintenance. The produced mechanism sand meets the national construction sand standard, the product has a uniform particle size, good granular shape and reasonable gradation.
The equipment configuration of the sand production line is mainly determined by the customer’s specifications for the sand and the output and the use of the sand. We provide the solution and technical support, configure the process according to the customer’s production site, and strive to achieve a reasonable and economical production line for the customer.
