The main component of limestone is calcium carbonate. Limestone is extensively used for building materials, industrial raw materials. It is high-quality raw material of sand and gravel aggregate.
Limestone Mohs hardness of 3, belong to the low hardness material. To produce sand and gravel aggregate, we can choose the configuration of "jaw crusher+impact crusher+sand making machine".
Jaw crusher is coarse crushing for limestone. Large pieces of limestone is crushed to medium size, like 10-30 cm. Impact crusher is medium fine crushing. The material can be further broken, after impact crusher processing can produce 0.5,1-2,1-3,2-4,3-8 and other specifications crushed stone aggregates. Sand making machine is fine crushing and shaping for stone and scrap, to produce 1-5mm sand to instead of natural sand. The sand is used in concrete mixing plant, dry mortar, building, paving and other projects. In addition to the host, vibrating feeder, vibrating screen, sand washing machines and other equipment are also essential. Liming Heavy Industry can provide complete solutions and process design.
