Limestone is a common nonmetallic minerals,It is widely used in the Mechanical and Production Engineering Technology industry as casting sand, coating of the building materials industry, in desulfurizing agent product, as the filler in plastic and paint production processing.
Basic the usage of the final production, the limestone crushing plant includes limestone crusher and limestone Grinder mill. The Recommend Machine is PE jaw crusher, PFW impact crusher, Raymond mill, MTM Medium Speed Trapezium Mill, MTW Continental Trapezoid Mill are the best choices for limestone powder production, because its’ Product fineness can be justify from 30mesh to 400mesh.
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, it can crush the material from 1m to –25 mm size.
The crushed limestone will be sent by a belt conveyor to vibrating screen becoming final products or to grinding mill to fine grind.
If the raw limestone is small enough and can be directly grinded by grinding mill, it can be grinded directly.
Limestone introduction
Limestone is the trade name of limestone as mining raw material, it has a very wide distribution with abundant reserves, it is an important road construction material, and also it is an important material for calcinating lime and cement, it is an indispensable high calcium lime to metallurgical industry, after ultrafine grinding, high quality limestone can be widely applied in the production of paper making, rubber, paint, coating, medical, cosmetic, feed, sealing, adhesion, polishing. The compressive strength of limestone is typically about 150 MPa, it belongs to soft rock, and therefore impact crusher is adopted for the production process of limestone production line. The proven Hazemag impact crusher is used in Liming limestone production line, it is a new type of impact crusher with high efficiency, and is suitable for crushing limestone and sandstone, 95% of crushed material<45mm.
Basic process of limestone production line:
Firstly, the stone will be evenly conveyed by feeder to jaw crusher for primary crushing, after primary crushing, the semi-product will be conveyed by belt conveyor to impact crusher for further crushing, after secondary crushing, the stone will be conveyed by belt conveyor to vibrating screen for sorting, different sizes of stone are sorted, the stone with desirable particle size will be conveyed to the final product pile, oversize will be conveyed by belt conveyor to impact crusher for crushing again, and closed circulation is formed.
Features of limestone production line:
The limestone production line has the features of high crushing efficiency, low power consumption, easy adaptation (particularly in crushing brittle material with middle hardness), and high crushing ratio, the process has been simplified to save the investment. Liming can provide customers with comprehensive process solution and technical support, and also can design non-standard parts according to actual installation conditions of customer.
