Vertical roller mill is a high-yield, high-efficiency, energy-saving and environmentally friendly production line equipment, from equipment R & D and design to equipment manufacturing and processing. Close control, using professional production technology knowledge for scientific and rational production, all production performance indicators have been greatly improved, is the ideal equipment for processing limestone powder.Limestone is a non-metallic ore resource that is widely distributed in nature. It is distributed in almost every province and city in China and has abundant reserves. In recent years, China's non-metallic ore milling industry has developed by leaps and bounds. As a kind of non-metallic ore resource with high development value and high comprehensive utilization value, ultra-fine grinding of limestone materials can improve the limestone market efficiency and enhance the status of limestone industry.vertical mill mill is an upgraded production line equipment of traditional mill, capable of ultra-fine grinding of limestone, producing high-quality limestone powder, power plant from limestone powder, etc., meeting limestone in power plants, chemical industry, metallurgy Application requirements in the field.
