Basalt (basalt), oceanic crust is mainly composed of basic volcanic rocks. It is not only the most important component of the earth's oceanic crust and lunar sea, but also an important component of the earth's continental crust and lunar land. Basalt is a kind of basic ejecta rock [1], 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. The mineral composition is mainly composed of basic feldspar and pyroxene, and the secondary minerals are olivine, hornblende and biotite. The rocks are dark, generally black, sometimes grayish green and dark purple. It has a speckled structure. Pore structure and amygdaloidal structure are common. The bulk density of basalt is 2.8-3.3 g / cm3. The compressive strength of basalt is very high, which can be as high as 300 MPA, sometimes higher, and decreases in the presence of vitreous and blowhole. Basalt has high durability, many joints, and most of the joint planes are hexagonal. Because of its brittleness, it is not easy to get large stones. Due to the common structure of stomata and amygdaloidal, basalt is widely distributed on the surface, but it is not often used as facing stone.
Basalt is a kind of material with high hardness and high silicon content, which is difficult to crush or has high crushing cost in the actual crushing operation. Generally speaking, basalt is a hard and tough material with a high content of silicon. Therefore, in order to design the basalt crushing production line reasonably, while considering the investment cost of crushing project, we must consider the production cost of basalt production line. In the crushing operation of basalt, the loss of wear-resistant parts such as jaw plate, plate hammer, impact plate and so on are very high. The production cost of customers is much higher than that of limestone. Therefore, in the design of crushing technology, we choose the crushing equipment based on the lamination principle as far as possible to reduce the loss of wear-resistant parts. A typical laminating equipment configuration is a two-stage jaw crusher or jaw crusher plus cone crusher process configuration. If the market has certain requirements for the grain shape of the finished stone, and users want to reduce the ton cost of wearing parts, they can consider coarse jaw crusher + fine jaw crusher / cone crusher as primary crushing and secondary crushing, and impact crusher is placed in the third crushing position, mainly for the purpose of shaping. In this way, not only the wear cost of impact crusher is reduced, but also the stone with good grain shape can be obtained.
Basalt crushing and sand making is a very popular industry, although basalt distribution is not as extensive as granite, but the reserves are also very considerable. Yusheng heavy Industry is a well-known crusher expert enterprise in China, with more than 20 high and new technologies, which is a veritable high-tech enterprise. We manufacture a full set of basalt crushers, including large jaw crusher, impact crusher, cone crusher, VSI vertical shaft impact crusher, vibrating screen and other advanced equipment, we can design the production line that is most in line with the actual conditions of customer site to ensure that customers can safely put into production and get stable profits. We will bring you to the factory to visit and know the production strength in detail, and come to the sand gravel production site to watch the working status of basalt crusher, to understand the value of investment, and to ensure that you have the most detailed understanding of all aspects of investment, so that the road of your investment is clearer and the income becomes a reality.
Basalt is the best stone material used to repair roads, railways and airport runways, with strong compression resistance, low crushing value, strong corrosion resistance, asphalt adhesion basalt. Basalt has the advantages of wear resistance, less water consumption, poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion resistance, asphalt adhesion and so on, and has been internationally recognized as the best cornerstone for the development of railway and road transportation.
Basalt is also a good raw material for the production of cast stone.
"cast stone" is a material made of basalt after melting, casting, crystallization and annealing. It is harder and more wear-resistant than alloy steel and more corrosion-resistant than lead and rubber. Basalt also plays the role of "lubricant" in an advanced process of steel casting, which can prolong the life of casting film. At the same time, basalt can also be drawn into glass fiber, which is better than ordinary glass fiber cloth in alkali resistance and high temperature resistance. Among them, the porous basalt, also known as pumice, has many pores and hard texture, which can be mixed into the concrete, which can reduce the weight of concrete, not only firm 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 still a good grinding material, which can be used to grind metal and stone, and it can also be used as filter, dryer, catalyst and so on in industry.
