Limestone is widely used in construction field and chemical industry, which is not only the raw materials for producing slaked lime, lime slurry, lime putty, lime mortar, aerated concrete block, coating, wall materials and other construction materials, but also be made into lime powder desulfurizer that used in power plant desulfuration field, or to be produced into the mechanism sand to make high performance concrete.
There are many types of limestone crushers. Different crusher has different application. The limestones exploit from the mine are crushed into 70mm in size through the jaw crusher firstly, and then following the secondary crushing for medium-fine crush. The qualified products are screened out, but the unqualified materials are fed into the tertiary crushing machine and finally screen the sand smaller than 0.475mm and other different size of stone. The one that need to be produced into lime powder is directly grinded.
What is mentioned is if the produced limestone products are used in construction fields, the discharging granularity should be as fine as possible. In this way, we need to add sand making machine since its crushing capacity is far beyond the other similar crushing machine, which is the most optimal sand making machine.
In addition, if the limestone is used as the construction stone or concrete aggregates, it's better to choose impact crusher. Because impact crusher has the function of aggregates shaping and sand making, it can produce the good shape products and reasonable matching stone and sand to enhance the concrete performance.
