Limestone was mostly calcium carbonate (CaCO3), mohs hardness is 3. Limestone are mined from limestone, subject to crush limestone particle formation, namely, stone, sand, or further grinding formation limestone powder, can be widely used in building material, highway, metallurgy, chemical industry, etc. Ore crusher equipment in this process played a crucial role.

Limestone processing technology

Usually limestone or limestone resources, ore grade can meet the requirements of various industrial departments.Therefore, generally only need for a simple washing, don't need to take on complex ore dressing process for purification.Processing mainly limestone crushing, grading and production quicklime and hydrated lime, precipitated calcium carbonate, carbon dioxide, and so on.Generally adopted dry grinding process, limestone for metallurgy, road with limestone, the ore after crushing screening.For fine powder production, ore by the jaw crusher, counterattack crusher and cone crusher broken with Raymond mill grinding, directly after the product fineness in about 100-325 mesh.

When it was broken limestone, moisture content will affect the choice of the ore crusher.When moisture content is too large, the material viscosity increases, can block the discharging mouth limestone affect the normal production.So we should according to the nature of the material and hardness characteristics to determine what type of crusher equipment choice.
