Features of mill equipment commonly used for processing 425 mesh limestone

According to the hardness of the processed material, the fineness of the discharged material and the output, the mill can be divided into three types: Raymond mill, superfine mill and superfine vertical mill. Lime powder is ground by a lime powder mill and used in construction engineering, power plant desulfurization, concrete mixing stations, highways and other infrastructure constructions. Lime powder is in the form of powder, and its content is mainly calcium oxide (CAO) and Magnesium oxide (MGO), these two substances play a decisive role in the strength of the fly ash crushed stone base, especially after the hydration reaction with fly ash, the influence of its content is more significant, a certain limit The increase of lime dosage can naturally improve the strength of fly ash crushed stone. Lime powder is currently widely used in the market, and its investment, production and processing costs are low.

Lime powder processing process: crushing, put large pieces of lime into jaw crusher or impact crusher for crushing. Grinding, and then through the vibrating feeder, the lime is evenly sent to the upper part of the turntable, and then fully ground in the mill through the centrifugal rate, at this stage, the lime can be processed into a fine powder between 80-325 mesh, Its output can reach 50 tons per hour. Sieving, the limestone powder ground by the pulverizer is ground by a vibrating sieve, the limestone powder that meets the mesh size is sieved out by the sieve, and the unqualified limestone powder will continue to be put into the pulverizer for grinding. Bulk packing is finished product.
