Basalt properties

Basalt is 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 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, basalt can also be drawn into glass silk, which is stronger in alkali resistance and high-temperature resistance than ordinary glass silk cloth. Among them, porous basalt, also known as pumice, has many pores and is hard in texture. It can be mixed in concrete to reduce the weight of concrete. It is not only durable but also has the characteristics of sound insulation and heat insulation. It is a high-rise building with Good aggregate for lightweight concrete.

Basalt crushing process

The Mohs hardness of basalt reaches 5-7, and the SiO2 content is 45%-52%. Therefore, impact crushers are generally not used for basalt crushing, and cone crushers are used for medium and fine crushing operations in the second and third stages.
