BASALT CRUSHING PLANT
Basalt volume density is 2.8-3.3g/cm3,compression strength is very big,can reach as high as 300MPa,and even more higher sometimes. Basalt have big durability,and fragile. Basalt main ingredient is silica,Al2O3,Fe2O3,CaO,MgO(and a small amount of K2O,Na2O),mostly is SiO2,about 45-50%. Commonly the color of basalt is black,blown or dark green. Because of its dense texture,basalt is heavier than granite,limestone,sandstone and shale.
Basalt process technology:
Because of basalt is very hard and contains a lot of Si,it is very hard to be broke and need high crushing cost. When process basalt,it is necessary to consider the reasonable design and the investment cost and also take the processing production line cost into consideration. When crush basalt,the spare parts of crushers are easily to worn down,such as jaw plate,hammer plate,impact plate etc. So when design the crushing solution,try to use laminated crushing equipments to reduce the wastage of spare parts. Typical laminated equipment is two sets of jaw crusher or jaw crusher work together with cone crusher production line.
Basalt is the best materials to do road construction,railway and airport runway,it has good pressure resistance,strong corrosion resistance,and strong asphalt adhesion,less water,poor conductive performance,is considered as the best stones to do railway and road constructions. Basalt is a good material to produce cast stones,it is harder and higher wear resistant than alloy steel,better corrosion resistance than lead and rubber. Basalt is also a good lubricant,it can be changed into glass,good high temperature resistant performance. Pumice is a good grinding material,can be used to grind metal,stones. And can also be used as filter,dryer,catalyst etc.
