Ultra-fine Milling Process of Ground Calcium Carbonate
“Ground calcium carbonate” is calcite in powder, also the ground calcium carbonate for short, which chief constituent is chief constituent. It is often used for filling, dry-mixed mortar of paper making industry, 325 mesh Calcium for concrete, construction industry, scagliola; 400 mesh Calcium for floor tile; 600 mesh Calcium for fire-barrier ceiling; 400 mesh Calcium for rubber industry and plastic industry; 800 mesh or 1000 mesh Calcium for paint and water paint. Calcium has been widely used. The equipment for processing the Calcium is T130X strengthened ultra-fine flour mill produced by SBM The series of grinding mill is improved 2~8 times in production yield under the same energy consumption, which has solved the big difficulties of low yield for traditional grinding mill. On the basis of original milling equipments, T130X series ultra-fine grinding mill can be up to 3250 mesh in fineness of final product, which fully meets the requirement of processing techniques for industrial calcium carbonate powder. Besides, ultra-fine grinding mill produced by SBM can cancel crushing chamber in cement production techniques, which only serves to final fine grinding and control particle size and particle constitution, and also, system capacity will be improved by 100%, energy consumption will be reduced by 24~30%, which can effectively reduce energy consumption, and production cost in cement enterprises and enhance effectiveness.
Limestone materials are easily broken, one is the hardness is low (4 to 5), the other is very low silicon content. Therefore, limestone as raw materials stone quarry production costs are relatively much lower. So, on the limestone crushing production line we can use broken jaw broken plus program counter, both get good stone grain type, crusher wear parts can have a long life. Typically, a jaw plate with one or two years time the situation is normal.
Coal is one of the most important energy, which plays an extremely important role in social and economic development. Development and use of coal, both played a huge role in promoting socio-economic, but also had a significant impact on the environment. Coal gangue and coal bed methane is the main waste generated in the development process which has long been regarded as hazardous substances and hazards gas in the coal industry. Coal gangue is discharged as solid waste in the tunneling, mining and washing process which is a mixture of carbon, clay and sandy shale, with low heat value.
One of the most innovative projects carried out in recent years by SBM Machinery’s Technological Sector is an in-depth study of the hard materials contained in porcelain tile bodies.
Recovering ceramic projects is a well known problem that exists in the ceramic industry and the most suitable solution, seeing the high costs of disposal and consequent environmental impact, is the possibility of recycling them in productive systems through extremely efficient Technology that creates advantageous objectives in terms of economy (cost of raw materials), technology, (using the Chamotte in the mixture without lengthening the milling cycles) & environment. 
SBM Machinery proposes solutions for the processing and milling of dolomite. Thanks to a technology based on the interaction between different machines offered by SBM Machinery, it is possible to realize the dry milling of the dolomite, nowadays used as weighing additive in drilling fluids or muds for petroleum industry.
