River pebble is a kind of pure natural stone. It is taken from the sandstone mountain produced by the uplift of the ancient river bed after the crustal movement of tens of thousands of years ago. The sharp edges and corners became rounded after being rubbed and rubbed by the gravel, and then buried deep underground together with the sand for silence for millions of years.


River Stone



The main chemical composition of river pebbles is silicon dioxide, followed by a small amount of iron oxide and trace elements such as manganese, copper, aluminum, and magnesium. They have different pigments, such as red for iron, blue for copper, purple for manganese, yellow translucent for silica colloidal stone, emerald green minerals, etc.; due to the dissolution of these pigment ions into dioxide The types and contents of the silicon hydrothermal fluids are different, so they show a variety of shades and shades of color, making the river pebbles show black, white, yellow, red, dark green.

Cone crusher production line

River soft rock crushing process

According to the actual production situation, the material crushed by the jaw crusher can be treated in two ways: first, it is stored in the transfer pile first, and then the material is divided by the transfer pile; The better river pebble crusher is the cone crusher)


jaw crusher


For river pebbles, the shape is regular, and it is basically good for landscape stones and garden stones; the unsightly appearance is mostly used for crushing sand. The sand making process of river pebbles requires many equipments. According to the size of river pebbles, different crushing equipment can be selected. For large-size feed, we use jaw crusher as the primary crushing equipment. For secondary crushing, hydraulic cone crusher can be used to replace impact crusher, which achieves the effect of high output and less wear. Complete the production of construction fine aggregate.
