The Application of vertical roller mill in basalt
The main components of basalt are silica, aluminum oxide, iron oxide, calcium oxide, and magnesium oxide (as well as a small amount of potassium oxide and sodium oxide), of which the highest is the silica, accounting for about 45 percent. About fifty percent of the color of basalt is usually black, dark brown or dark green. Due to its dense texture, its proportion is heavier than that of granite, limestone, sandstone, and shale. However, there are also basalts that have a large number of pores, which reduce their weight and even float in the water. Therefore, this kind of porous basalt, called "pumice" basalt, has a Mohs hardness below 9.3 and humidity below 10%, which is convenient for processing and processing.
There is a kind of material called basalt in the material milled by the vertical roller mill. The use of basalt is very extensive in our lives. Basalt is the best material for repairing roads, railways and airport runways. It has strong compressive strength, low crushing value, strong corrosion resistance, asphalt adhesion basalt stone, and basalt stone wear-resistant, low draught, Poor electrical conductivity, strong pressure resistance, low crush value, strong corrosion resistance, asphalt adhesion and other advantages, and internationally recognized, is the best foundation for the development of rail transport and road transport. Moreover, basalt is a good raw material for the production of "cast stone." The cast stone is a material obtained by melting and casting basalt, crystallizing, and annealing. It is harder and more wear-resistant than alloy steel and more resistant to corrosion than lead and rubber. Basalt is also in the advanced technology of cast steel, playing the role of lubricant; it can extend the life of cast film. At the same time, basalt can also be drawn into glass filaments, which is more resistant to alkalis than normal glass filaments and has good high temperature resistance. And some artists, according to the pumice porous and wrinkled, leaking features. It is used to build the rockery in the garden, or to form a small and exquisite bonsai. Basalt is a basic volcanic rock. It is the most important component of the earth's oceanic crust and the moon's lunar sea, and it is also an important component of the earth's continental crust and lunar lunar land.
