Basalt crusher basalt lithotripsy bas 


Basalt, mainly composed of oceanic crust, belongs to basic volcanic rocks. It is the most important component of the earth's oceanic crust and lunar sea, and also the important component of the earth's continental crust and lunar land. Basalt is a basic extrusive rock. Its chemical composition is similar to gabbro. The content of SiO₂ varies from 45% to 52%, the content of K₂O + Na₂O is slightly higher than that of intrusive rock, and the content of CaO, Fe₂O₃  + FeO and MgO is slightly lower than that of intrusive rock. Minerals are mainly composed of basic feldspar and pyroxene. Secondary minerals are olivine, hornblende and biotite. Rocks are dark, generally black, sometimes grey-green and dark purple. A porphyritic structure. Stomatal structure and almond structure are common. The volume density of the basalt is 2.8-3.3 g/cm³, and the compressive strength of the compacted basalt is very high, up to 300 MPa, sometimes higher. The strength decreases with the presence of vitreous and stomata. The basalt is highly durable and jointed, and the joints are hexagonal. Because of its brittleness, it is difficult to extract large blocks of stone. Because of the common stomatal and almond structures, although basalt is widely distributed on the surface, it can not be used as a decorative stone.

Basalt Processing technology

Basalt has high hardness and high silicon content, so it is difficult to crush in actual crushing operations or materials with high crushing cost. Popularly speaking, basalt is hard and tough material, and silicon content is very high. Therefore, in order to design the process of basalt crushing production line reasonably, we must consider the cost of basalt production line while considering the investment cost of crushing project. In the crushing operation of basalt, the abrasion of wear parts such as jaw plate, hammer and impact palte is very high. The cost of production is far greater than that of limestone. Therefore, in the design of crushing process, we choose the crushing equipment of lamination principle as far as possible to reduce the abrasion of wear parts. The typical lamination equipment is a two-stage jaw crusher or a jaw crusher plus cone crusher process configuration. If the market has a certain requirement on the grain size of finished stone, and the user wants to reduce the tonnage cost of vulnerable parts, we can consider coarse jaw crusher plus fine jaw crusher or cone crusher as primary and second crusher. The impact crusher is in the tertiary crushing position, mainly for the purpose of shaping. This will not only reduce the abrasion and tear cost of the impact crusher, but also get the stone with good grain shape. Basalt fragmentation sand making is a very popular industry. Although basalt is not widely distributed as granite, its reserves are also very considerable. Vanguard is a well-known crusher expert enterprise, with more than 20 high-tech patents, is worthy of the name of high-tech enterprises. We produce a complete set of basalt crushers, including large jaw crusher, impact crusher, cone crusher, VSI impact crusher, vibrating screen and other advanced equipment, can design the most in line with the actual situation of the customer site production line, to ensure that customers can safely put into production, to obtain stable returns. We will take you to the factory to inspect the production strength in detail, to the sandstone site to watch the working state of the basalt crusher, to understand the value of investment, to ensure that you understand the most detailed aspects of the investment on all aspects of the problem, is your investment road more clear, the profits become a reality.
Basalt is the best material for building runways of highways, railways and airports. It has the advantages of strong compression resistance, low crushing value, strong corrosion resistance and asphalt adhesion. Basalt has the advantages of wear resistance, less water intake, poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion resistance and asphalt adhesion. Internationally recognized, it is the best cornerstone for developing railway transportation and road transport. Basalt is also a good raw material for producing "cast stone". "Cast stone" is a material made of melting, casting and annealing of basalt. It is harder and more wear-resistant than alloy steel, and is more resistant to corrosion than lead and rubber. Basalt also acts as a "lubricant" in an advanced steel casting process, which can prolong the life of the cast film. At the same time, the basalt can also be drawn into glass fiber, than the general glass cloth alkali resistance, high temperature resistance. Among them, the porous basalt, also known as pumice, has many pores and hard texture. It can be mixed into concrete to reduce the weight of concrete. It is not only strong and durable, but also has the characteristics of sound insulation and heat insulation. It is a good aggregate for lightweight concrete in high-rise buildings. Pumice is also a very good grinding material, can be used to grind metal, abrasive stone; in industry can also be used as filters, dryers, catalysts and so on.

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