Basalt's main ingredient is silica and the content is about 45% to 50%, and it has compact texture. Its specific gravity is heavier than the average granite, limestone, sandstone, shale; but because some basalt have many stomas, so that the weight will be reduced, even can float in the water, so it also known as the "pumice stone". Basalt with higher hardness, higher silicon content, it is difficult to crushing. So, we should design the basalt crushing process reasonable, according to the finished product use, consider the cost of production.
Use of finished product：
Basalt is the best materials used in the stone in the construction of roads, railways, airport runways, with the high anti-compressive low crushing value, corrosion resistance and adhesion of asphalt, wear resistant, less water consumption, the advantages of high insulating, which internationally recognized as the best cornerstone for the development of rail transport and road transport and has broad development prospects.
1. basic configuration
Because basalt hardness and silicon content is high, it is difficult to crushing and corrosive. The wastage of crusher wear parts such as the loss of the jaw plates, plate, hammer, back plate is very high. To reduce energy consumption and wastage, especially recommended typical layer pressure device configuration - two-stage jaw crusher or jaw crusher plus cone crusher. This basic configuration is mainly suitable for quarry stone grain shape which has less demand. Jaw crusher, CS cone crusher both use laminated crushing principle, the wear of the wear-resistant parts are relatively small, and production costs will be relatively low. However, due to the use of laminated principle, it will lead to a not very good grain shape. Needle flake stone's content is relatively high within the cracks of the stone, so the market price is lower than the back-breaking finished materials.
2. Three stage crushing to create high-quality grain type
If the customer is finished stone grain type have certain requirements, customers want to reduce the cost of wearing parts, could be considered coarse jaw crusher + fine broken jaw / cone break as the first break with two broken crusher on the third Road location broken play the purpose of crushing and integer; so the formation of a three-stage crushing process not only reduces the cost of impact crusher wear, you can also get good grain shape stone; counter-attack to break the biggest feature is the ability to produce grain type high quality of stone, with a double crushing and integer performance; three stage crushing investment is large, but the good grain shape stone due to the good mechanical properties, mechanical properties and widely favored by the large builders, the market is good, the price is high for STONE QUARRY, production costs and economic benefits of long-term operation is extremely impressive.
Specific process configuration should be based on the specific analysis of the actual situation of the customer site. Welcome to visit and experience Kefid's star service!
