Title How to choose sand crushing equipment for producing highway materials with basalt
Description Basalt is a basic extruded rock. Its chemical composition is similar to that of gabbro or diabase. The content of SiO2 varies from 45% to 52%. The content of K2O + Na2O is slightly higher than that of intrusive rocks. CaO, Fe2O3 + FeO MgO content is slightly lower than intrusive rocks. The mineral composition is mainly composed of basic feldspar and pyroxene. The minor minerals are olivine, amphibole and biotite. The rocks are dark, generally black, sometimes gray-green and dark purple. It has a patchy structure. Stomatal structures and almond structures are common. Basalt is used as an asphalt mixture. The specifications of the crushed stones used in each layer of asphalt pavement are not the same. The bottom layer is large and the upper layer is fine. Therefore, basalt is not only used to sand making machine for road materials, but mainly uses more materials below 20mm. This requires us to use targeted equipment to complete. Basalt has high hardness and brittleness. For materials with high hardness, we are suitable for breaking, and for materials with large brittleness, it is suitable for impact. Then cone crusher and sand making machine are useful. The selection of basalt crushing sand making equipment should still be equipped with multiple crushing modes. This is not only conducive to the optimization of grain shape, but also to the improvement of yield. The directions recommended by Shanghai SBM are: the first crushing or jaw crusher, the second crushing using cone crusher, and the third crushing using high-efficiency sand making machine (also can be used as return equipment), with screening and feeding , Feeding and other equipment. Basalt is expensive and profitable. If you can choose the equipment and configure a reasonable production line, you can do more with less.
