Product Introduction

Basalt is a kind of basic extrusive rock, a compact or foam-like structure formed by the solidification of magma from a volcano after the surface is cooled and belongs to the magmatic rock. The hardness of basalt is 5-7 in Mohs, and the volume density is 2.8～3.3g/cm3. The dense structure has high compression strength, which can reach 300MPa, or even higher, but the strength will be reduced if the crystal impurities and stomata are contained.

Basalt is also a kind of high quality transportation construction stone, and one of the best construction materials especially in the construction of road, railway, port, airport runway and other works. With the characteristics of high compressive strength, low crushing value, wear-resisting, low bibulous rate, weak electrical conductivity, strong corrosion resistance and strong asphalt adhesion, basalt is the best cornerstone of the development of railway and road transportation.

At the same time, because of the excellent anti-pressure and anti-bending conditions, good wear resistance and low water absorption rate, basalt is good building decoration material. It can be widely used in indoor and outdoor decoration, and is mainly used as outdoor stone material. Its color is natural and it can coordinate well with the surrounding landscape. It is very suitable for outdoor landscape construction, especially the best choice of floor stone. The basalt is easy to form the six-pillar joints and is fragile, so the stone material shortage is generally small, and is lack of big material and not easy to produce large specification of plate.

 Technical Process

The process of basalt sand production line: The basalt enters coarse crushing equipment through feeder. After coarse crushing, the aggregate enters fine crusher for second crushing. Then it is transported to screening device by belt conveyor for aggregate classification. After satisfying the required finished aggregate, the unnecessary aggregate and the aggregate whose grading doesn’t meet the requirement will be sent into sand making equipment. After crushing of sand making machine, the aggregate is transported again to screening workshop by belt conveyor for grading. In this way, the secondary crushing device, sand making device and the screening device form a closed-loop cycle, and the aggregate is processed into the required finished stone aggregate. Dry or wet process can be used in the production of artificial aggregates. In the case of considering environmental protection and water saving, winnowing machine can be used for sand classification, which is conducive to environmental protection and the adjustment and control of stone power content at any time.
