Cobblestone is a by-product of the exploitation of yellow sand because it is named after the goose egg. Cobblestone, as a kind of natural stone, is taken from the sand and stone hills which were uplifted by the ancient river bed after the crustal movement of tens of millions of years ago, and is subjected to constant extrusion and friction during the process of torrential impact and flowing water transportation. In the course of tens of thousands of years of vicissitudes, they have suffered from the movement of waves, were rubbed by gravel collision loss of irregular edges, and with the sediment buried deep underground silence for millions of years. Cobblestone products are: natural color mechanism cobblestone, River pebble, rain flower stone, dry clay stone, spray stone, landscaping stone, wood fossils, cultural stone, natural color marble rice and other building decorative materials and high-grade dyed sand for interior decoration, non-toxic, tasteless, non-decolorizing. It is a kind of ideal green building material with the characteristics of hard quality, bright color and primitive simplicity, compression resistance, wear resistance and corrosion resistance.

Cobblestone Processing technology

With the accelerating pace of highway and urbanization construction, the rapid development of construction industry, the demand for construction gravel is increasing. However, due to the uneven distribution of rock and pebble geographic resources, resulting in the shortage of artificial gravel and pebble in some areas, at this time people have to favor broken pebbles. The exploitation and application of stone, for example, cobblestones or broken cobblestones are used in the construction industry of the first-class highway and other highways and cities in most areas of Sichuan Province, including the cushion graded gravel and cement stabilized gravel floor in most of the bridge structures and pavement structures of highways in China. Cobblestones and broken cobblestones are used in the base course. A large number of tests have proved that the processed broken cobblestones have the double advantages of cobblestones and artificial broken stones. It not only improves the physical indexes of cement concrete, but also improves the characteristics of shrinkage and cracks of pumped cement concrete, and improves the crack resistance of concrete. Good technical, economic and social benefits have been obtained. It can be called "green building materials". Pebble crusher is often used in the first or second crushing of mine materials. The pebble crusher adopts the most advanced crushing technology and manufacturing level in the world. It is the first choice of high efficiency products for crushing many hard and strong abrasive materials. It mainly crushes hard rocks such as pebbles. The specifications are about 3-7 cm. The hardness of crushed materials is relatively large. Compared with the traditional crusher, Vanguard cobble crusher has its unique advantages in service life, maintenance rate and failure rate. The cobblestone crushing production line is composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, centralized electronic control and other equipment. According to different technological requirements, various types of equipment are combined to meet different technological requirements of customers.
Pebbles are widely used in public buildings, villas, courtyard buildings, paving roads (pebble roads built in the park have the effect of prolonging life), Park rockeries, bonsai filling materials, garden art and other high-level superstructure. It not only promotes the ancient culture of the East, but also reflects the classical style of the West. Cobblestones also provide high-quality materials for water purification, sewage treatment, electricity, gardens and other projects. It also provides raw and auxiliary materials for ceramics, precision casting, paper making, spray grinding, chemical industry, monocrystalline silicon, national defense and so on. The pebbles can be widely used in hydraulic and Hydropower projects, high-grade highways, expressways, high-speed railways, passenger dedicated lines, bridges, Airport runways, municipal engineering, high-rise building sand production and stone shaping.

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