Pebble, which is by-product of mining yellow sand, named for its shape like goose eggs. As a kind of pure natural stone, pebble is taken from the sandstone mountain produced by the uplift of the ancient riverbed after the crustal movement of tens of millions of years ago, and it is constantly squeezed and rubbed in the process of mountain torrent impact and running water transportation. In the course of tens of thousands of years of vicissitudes life, it has been washed by waves, lost their irregular edges and corners by gravel collision and friction, and has been buried deep in the ground with sediment for millions of years. Pebble products are: natural color mechanism pebbles, river pebbles, Yuhua stone, drydash, spray stone, landscaping stone, wood fossils, cultural stone, natural color stone and other architectural decoration materials and high-grade dyed sand for interior decoration, non-toxic, tasteless, non-decolorizing. It is a kind of ideal green building material with hard quality, bright and simple color, and natural stone characteristics of pressure resistance, wear resistance and corrosion resistance.
With the accelerated pace of highway and urbanization construction and the rapid development of the construction industry, the demand for building gravel is increasing day by day. However, due to the uneven distribution of rock and pebbles geographical resources, it leads to the shortage of artificial gravel and pebbles in some areas. At this time, people have to favor the mining and application of broken pebbles. For example, pebbles or broken pebbles are used in first-class roads and other roads and urban construction industries in most areas of Sichuan Province. Including the cushion graded macadam and cement stabilized macadam subbase of most bridge structures and pavement engineering structures in many expressways in China, pebbles and broken pebbles are used. It is proved by a large number of experiments that the processed and broken pebbles have the double advantages of pebbles and artificial macadam, which not only improve the physical indexes of cement concrete, but also improve the crack resistance of pumping cement concrete. At the same time, good technical, economic and social benefits have been obtained. It can be called "green building materials". The pebble crusher is often used for primary crushing or secondary crushing in the crushing of mine materials. The pebble crusher adopts the most advanced crushing technology and manufacturing level in the world, it is the first choice for crushing hard and abrasive materials. Mainly with broken pebbles and other hard rock, the specification is about 30mm-70mm, and the hardness of broken material is relatively high. Compared with the traditional crusher, the Yusheng heavy industry pebble crusher has unparalleled advantages in terms of service life, maintenance rate and failure rate. The pebble crushing production line is composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, centralized electric control and other equipment. According to different technical requirements, various types of equipment are combined to meet the different technical requirements of customers.
Pebbles are widely used in public buildings, villas, courtyard buildings, paving roads (the pebble roads built in the park can prolong life), park rockery, bonsai filling materials, garden art and other advanced superstructures. It not only carries forward the ancient oriental culture, but also reflects the western classical, elegant and simple artistic style. Pebbles also provide high-quality materials for water purification, sewage treatment, electric power, gardens and other projects. It also provides raw and auxiliary materials for ceramics, precision casting, papermaking, spray grinding, chemical industry, monocrystalline silicon, national defense and so on. After being processed by crusher and sand-making machine, pebbles can be widely used in water conservancy and hydropower, high-grade highways, highways, high-speed railways, passenger dedicated lines, bridges, airport runways, municipal engineering and high-rise buildings of mechanism sand production and stone shaping.
