Basalt is an important part of the earth's crust. Basalt is formed after volcanic eruption, eruption of magma and cooling. The color of basalt is black, such as black, black brown and dark green. Basalts are very special, Some basalts are filled with pores and can float on the water, Some basalts are very dense. Basalt is widely used in the construction industry. In the construction of roads, railways, and airport runways, basalt is the most suitable material among all stone materials.
Basalt is widely regarded as a high-quality stone for the road and rail transportation industries because of its strong compressive ability, not easy to break, not easy to corrode, good adhesion to asphalt, very wear-resistant, and basically non-conductive.Mixing basalt with concrete with numerous pores can reduce its weight and have the double advantages of heat insulation and sound insulation.
Basalt has many uses, so it can be produced in large quantities. Therefore, the selection of basalt crusher is particularly important. Basalt is a kind of hard and tough material with high silicon content. In the actual crushing operation, it belongs to the material that is difficult to be broken and the material with high crushing cost. Therefore, the crushing process of basalt should be designed reasonably, and the production cost of the production line must be considered while considering the investment cost of the crushing project.
Basalt crushing scheme design:
Because basalt has very strong hardness and rich silicon content, during the crushing operation of basalt, the materials wear the wear-resistant parts such as jaw plate, plate hammer and impact plate seriously, which greatly increases the crushing cost of basalt. Therefore, according to the material properties of basalt, the crushing equipment based on lamination principle is used in the design of crushing process to reduce the loss of wear-resistant parts.
It is recommended that the user use jaw crusher and hydraulic cone crusher for the quarry with low requirements for stone particle size. However, due to the lamination principle, the internal cracks of the broken stone are serious, and the grain shape of the stone is not very good, and the needle like shape of the stone is relatively serious.
For customers who have high requirements for the final stone particle size, it is suggested to add a impact crusher to the original two-stage crusher configuration for integral crushing, because the impact crusher has the dual performance of crushing and shaping. The stone with good grain shape can add better stress performance to the building, and has a high price in the market.
Moreover, since the wear cost of vulnerable parts of impact crusher is higher than that of jaw crusher and hydraulic cone crusher with the same output, the process configuration of three-stage crushing will increase the investment cost of the project. However, for the stone plant with long-term operation, the production cost reduced by three-stage crushing is very considerable.
