Introduction of limestone grinding machine: 
- Five models: HGM80, HGM90, HGM100, HGM100A, and HGM125 
- Finished production fineness: 325meshes~2500meshes, 5-47micron 
-The capacity (ton/hour) ranges from 0.5T/H to 10T/H   

Application of limestone grinding machine: Limestone grinding machine is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs' hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials.     Features of limestone grinding machine: 1.High Efficiency Under the same finished final size and the same motor power, the capacity of the machine is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%. 2.Long lifecycle 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. 3.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. 4.High fineness, flexible adjustment The final fineness of the grinding materials can be adjusted between 325 meshes and 2500 mesh (47-5 micron), and the product fineness can reach D97≤5μm. 5.Environment-friendly
