Limestone is calcareous sedimentary rocks formed at the bottom of lakes and seas with the accumulation of shells, bones and other calcium rich goods. It is composed of calcite (CaCO3). The organic matter upon which it settles in lakes or seas are preserved as fossils. Over thousands and millions of years, layer after layer is built up adding weight. The heat and pressure causes chemical reaction at the bottom and the sediments turn into solid stone, the limestone. Limestone is important buiding materials, and raw materials for cement production. Natural limestone is big; we must crush them into suitable size through limestone crushing process or grind them into sand or powder in limestone grinding process.
Limestone crushing process needs limestone machinery. In this process, we usually use jaw crusher, cone crusher, mobile breaker such as limestone jaw mobile crusher, impact mobile crusher, cone mobile crusher, crawler type mobile crusher. These machines are used to crush limestone into smaller size. According to the different products, we choose the different crushing process. Usually limestone machinery includes primary crushing process and secondary crushing process. If the product is sand, the limestone particles must do stone shapping through sand making equipment. If you need the stone powder, using limestone grinding machines to grind these crushed limestone particles into powder. In this grinding process, hammer breaker, ball mill, vertical mill are usually used.
In complete set of cement equipments, limestone is the important raw material to make cement. It goes through crushing, grinding process, then make into powder. In casting sand production line, limestone is crushed into the particles with 58 - 57 mesh. This limestone sand is better than the performance of quartz sand in manufacturing of machinery.
Hongxing Machinery is a mining machine manufacturer in China, and provides all kinds of stone crushers and grinding mills, such as aggregate crusher (limestone crusher, marble crusher, granite crusher, and gravel crusher), ore crusher, coal crusher, cement mill, concrete crusher, and gold mining equipments.
