River Pebble Sand Making Machine Rive 


River pebble is a kind of pure natural stone. It is taken from the sand and gravel hills which were uplifted from the ancient river bed after the crustal movement tens of millions of years ago. It is constantly squeezed and rubbed during the process of mountain torrent impact and flowing water transportation. In the course of tens of thousands of years of vicissitudes and changes, they have experienced the movement of waves and washes, lost irregular edges and corners by the impact and friction of gravel, and were buried in the ground together with the sediment for millions of years of silence. The main chemical composition of river pebble is silicon dioxide, followed by a small amount of iron oxide and trace elements and compounds such as manganese, copper, aluminum and magnesium. They have different pigments, such as red iron, blue copper, purple manganese, yellow translucent silica colloidal pith, emerald green minerals and so on. Because of the different kinds and contents of these pigment ions dissolved in silica hydrothermal solution, they show a variety of shades of color. So that the river cobbles appear black, white, yellow, red, dark green, gray and so on. Most of the pebbles are near the Haihe River. Black sand grains are gathered on the pebbles. The pebbles should account for more than half of the volume. Because of their wide distribution, common appearance and beautiful appearance, they are ideal choice for yard, road and building construction.

Pebble Processing technology

River pebble is a kind of pure natural stone with abundant resources and low cost. Nowadays, natural sand is increasingly scarce, artificial sand making machine for river pebble has become a new trend. River pebble sand-making machine is a new generation sand-making machine specially developed for river pebble by our company after years of research and improvement. River pebble sand-making machine is designed according to the working principle and new technology of various crushers. Its typical use is to adapt to the current artificial sand-making industry. It is a cone crusher, bar grinding sand-making machine. The first product of the impact sand making machine and straight through sand making machine is upgrading. After optimized design of the deep cavity rotor, the material throughput is increased by about 30% and the service life of the machine is increased by more than 40%. The cost is greatly saved and the efficiency is improved. Flow of sand production line of river pebble: First, crusher crushes the stone preliminarily, the coarse material produced is transported from belt conveyor to fine crusher for further crushing, the stone is fine crushed into vibrating screen, vibrating screen screens them out of two kinds of stones, those meet the granularity of sand machine feeding stones, the other Some of the returned material enters the fine crusher, some of the stone enters the sand making machine to make sand, after washing sand machine to make finished sand, the other part of the stone will be broken again by the sand making machine. Anbanghe gravel sand production line is widely used in more than 300 kinds of materials processing and fine crushing in mines, cement, coal, metallurgy, building materials, highways, railways and other industries all over the country. The equipment of this production line is stable and reliable in operation, its process is very simple, and its structure is very simple. It is very convenient for maintenance.
Natural River eggs are processed by crushing, sand making, screening and so on. River eggs are important industrial mineral raw materials. It is widely used in hydraulic and Hydropower projects, high-grade highways, expressways, high-speed railways, passenger dedicated lines, bridges, Airport runways, municipal works, high-rise building sand production and stone shaping. River sand is widely used as aggregate for concrete. The river cobble is rich in resources, its acquisition cost is relatively low, and its application value is high.

Application fields Through the deep processing, Pebble can be widely used in the following industries.
