Calcium carbonate grinding mill in one of the stone powder grinding mills which especially used in calcium carbonate powder making. Compare with other common powder grinding mills, the calcium carbonate grinding mill is more used for calcite powder grinding, why do I say that? I will give you a reason. Calcium carbonate is one of very common nature stone minerals. So that the calcium carbonate is a widely distributed mineral. Calcium carbonate is used as a flux in metallurgical industry and used in the construction industry to produce cement and lime. It is also used in plastic, paper making, toothpaste. Filling additives in food. In glass production, the calcium carbonate ingredients are added, and the generated glass will become translucent, especially suitable for making glass lampshade. Compare with other calcium carbonate powder making machine, use calcium carbonate grinding mill to process calcium carbonate powder has lots of advantages as following: High efficiency Under the same finished final size and the same motor power, the capacity of ultra fine grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%. Long life cycle of spare parts The ring and roller are forged by special material with high utilization,the lifetime can reach 2-5 years for grinding calcite carbonate. High safety and reliability As no rolling bearings or screws in grinding cavity, there are no problems caused by bolts shedding or rapid wear of bearings and seal components. High fineness, flexible adjustment The final fineness of the grinding materials can be adjusted between 250 meshes and 2500 mesh (74-5 micron), and the product fineness can reach D97�5μm. Environment friendly The application of pulse bag filter and muffler greatly alleviates dust pollution and noise. Advanced intelligent speed control device Convenient adjusting, more uniform particle size.
