Pebble, a kind of natural stone material, derived from over thousands of years ago after the movement of the earth's crust uplift by ancient riverbed of sandstone in the mountains, mountain torrent shock, water transport in the process of continuous extrusion, friction, by gravel collision loss of irregular edges, finally become a hard quality, colour and lustre is bright, has the corrosion resistance of the pebble, compressive, wear-resisting is an ideal green building materials.

The hard, wear-resistant and corrosion-resistant properties of river pebbles enable them to be widely used in water conservancy and hydropower, high-grade highways, highways, high-speed railways, Bridges, airport runways, high-rise buildings, mechanical sand production and stone shaping. Because of relatively low acquisition cost, the pebble sand is also used in concrete aggregate and has high application value.

As a pure natural stone material, river pebbles are mainly composed of silicon dioxide and contain a small amount of iron oxide and trace amounts of manganese, copper, aluminum and other elements and compounds. Therefore, the crushing technology of river pebbles should not only be designed reasonably, but also take the investment cost of the crushing project into consideration. In the design of crushing process, the crushing equipment with lamination principle should be selected as much as possible to reduce wear - resistant parts loss. Generally, the technological configuration of two-stage gnat or gnat plus cone fracture is adopted. If there is a higher requirement for the final stone grain type, a counterpunch fracture can be configured for shaping and crushing, forming the technological configuration of three-stage crushing.


Pebble Jaw Crusher

The river pebble jaw crusher is mainly used for medium grain crushing of all kinds of ore and bulk materials. It can crush materials with compressive strength no more than 320Mpa. It is divided into two types: coarse breaking and fine breaking.It is widely used in mine metallurgy the building road and railroad construction hydraulic construction chemical industry fire-proofing material and ceramics.

Output size : 40-350mmCapacity : Up to 800TPH

Reliable technology, environmental protection and energy saving, convenient maintenance, small amount of maintenance, a machine multi-purpose.

Pebble Impact Crusher

River pebble impact crusher is used to break the river pebbles with the impact energy. Driven by the motor, the river pebbles repeatedly break into the counter cavity from large to small to the required particle size, and are discharged from the outlet.

Output size : Depends on the material Capacity : 50-350TPH

Strong processing capacity, high crushing efficiency, stability and reliability, low fault rate, easy operation and maintenance.

Pebble Cone Crusher

CS cone crusher of river pebbles is used for layered crushing of materials with strong randomness of product particle size. By adjusting the gap of crushing cavity, the ratio of required materials can be easily adjusted.

Output size : 9mm-64mm
Capacity : Up to 1270TPH(standard); Up to 599TPH (short head)

The structure is optimized to improve the crushing efficiency, the combination of crushing stroke, crushing speed and crushing cavity type increases the production capacity, and the finished products of the crushing principle make the grain type more excellent.

Pebble VSI Crusher

The new sand crushing equipment of river pebbles, which absorbs years of research and development experience and technical idea, adopts the new design structure of four impeller and special sealing structure to prevent oil leakage of bearing tube and other technological innovations, and is the shaping machine of river pebbles sand making.

Output size : Various sizeCapacity : Up to 800TPH

New design, high crushing efficiency, process upgrade, cost reduction and efficiency increase, quality assurance.


such as: Output size 0-10, 10-15, 15-20mm
