The deep processing and uses of limestone

Lime mineral resources is a common non-metallic minerals. China is rich in limestone mineral resources, accounting for more than 64% of the world's total reserves, it is a natural resources with advantages.

 

Limestone is widely used, but in order to protect the environment, its development and utilization is to be careful.We should take the shortest step, the simplest possible way, the most realistic of the market to improve market competitiveness. Currently, the most widely used of limestone is cement building materials. Limestone crushing or ore grinding are all able to meet the requirements of the cement material, can also be used as filler in paint and other production processes. There are calcium carbonate products, production of high-grade paper coating grade calcium carbonate products. Such high value-added fine, superfine and activity of heavy calcium carbonate in the papermaking process is widely used, general particle size after crushing - 2μm ≥90% for the neutral sizing paper making process; - 2μm diameter ≥50 % of coated paper is mainly used as filler. Another plastics and coatings.

                                                                                                

 

Limestone deep processing recycling process is processing limestone ore through primary, secondary crushing and grinding. We can produce 13,12,14 limestone gravel, building sand, also produces limestone powder for cement, paint, plastics, paper industry.The fineness is from 80 to 3250 mesh. The main grinding equipment is for 0-3MM field, 80-400 mesh powder field, 400-3250 mesh ultrafine powder field.
