Basalt is the good source of cast stone. The Moh's hardness of basalt is within 5-7 and the content of SiO2 reaches 45%-52%. Cast stone can be got by melting, crystallizing, annealing the basalt. It is harder and more wearable than alloy, more erosion-resistant than lead and rubber. Besides, there is an advanced steel casting technology where basalt functions as the lubrication agent to extend the life expectancy of casting film. Meanwhile, basalt can be made into fiberglass which owns higher alkali and high temperature resistance. Of all kinds of basalt, the porous basalt, also known as pumice stone, is rigid and can be added in concrete to lose the weight of concrete and insulate the noises and heat. It is the good choice for construction of high buildings.
BASIC PROCESS OF BASALT CRUSHING PRODUCTION PLANT
The Basalt crushing production line is divided into three stages: coarse crushing, medium fine crushing and screening.
The first stage: coarse crushing
The Basalt stone blasted from the mountain is fed uniformly by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing.
The second stage: medium and fine crushing
The coarsely crushed materials are screened by vibrating screen and then conveyed by belt conveyor to cone crusher for medium and fine crushing.
The third stage: screening
The medium and finely crushed stones are conveyed to the vibrating screen through a belt conveyor to separate stones of different specifications. The stones that meet the requirements of the customer's particle size are conveyed to the finished product pile through the belt conveyor. The impact crusher crushes again, forming a closed circuit cycle.
