Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite. Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera.
Limestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock.
Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints and as a chemical feedstock. Limestone and lime are widely utilized in metallurgical, chemical, construction, developing supplies, and environmental protection, agriculture, and food industries. It is ordinarily processed by jaw crushers , cone crushers, impact crushers and hammer crusher for crushing after which directly grinded by Raymond mill , vertical roller mill, and vertical impact mill in the whole limestone processing plants.
Limestone mining equipments are used widely in limestone crushing industry. Many limestone crushing plant includes limestone crusher and limestone mill or other related limestone crushing equipments. Limestone mining has important position in modern construction and road building industry because limestone is the most widely used stone or rock. DSMAC is a professional limestone mining equipments supplier and can supply you many limestone mining machines such as limestone mining crusher, limestone mining mill, limestone mining feeder and so on.
Limestone is very hard material, to use itsprofessional crushing machine, which is the professional crusher mining equipment, recommended: jaw crusher, impact crusher, cone crusher, ball mill.
Jaw crusher can be used as the primary crusher to the medium size crushing of various ores and large-size materials, with the anti-crushing pressure of less than 320Mpa. And the crusher can bedivided into two kinds such as coarse and fine crushing. And this series of crusher have complete specifications with the feeding particle size of 125mm~750mm, which have become the primary crushing equipment. And the jaw crusher can be used in the field of mining, metallurgy, building material, highway, railway, water conservancy and chemical, etc.
Impact crusher is widely used as the secondary crusher. Impact Crusher is mainly used to crush many kinds of large, medium, small materials, the side length of impact stone crusher is less than 500mm, and compression resistance of impact crusher should not be more than 350Mpa. The impact crusher is widely used in building material, hydroelectricity, artificial stone and sand, highway, etc.
If the raw limestone is bigger than the input size of your grinding mill, it should be crushed firstly. The proposed limestone crusher is impact crusher, which features reasonable structure, high productivity, easy operation and maintenance and safe performance.
In limestone crushing plant, stone blasts from the mountains and down through the dump truck, then the materials into the vibrating feeder, vibrating feeder send these materials evenly into the stone jaw crusher, jaw crusher machine is used for primary stone crushing, materials from a broken jaw crusher made out of stone in 150mm-300mm. Then vibrating feeder send materials into the impact crusher for secondary crushing, screening through circular vibrating feeder, at this time, if materials are greater than the material of the finished product will back to the back-breaking for re-broken, while the final products will send to the finished product area by belt conveyors.
