Coal mill is a device that uses grinding and processing equipment to reprocess raw coal. The pulverized coal mill can be widely used in the pulverizing system of electric power, metallurgy, building materials, chemical industry and other industries, especially the blast furnace pulverizing system that requires a large amount of bituminous coal.
In the process of grinding pulverized coal, the coal mill uses hot air (or hot flue gas) to dry the coal at the same time. There are many types of coal mills. It is necessary to select a low-speed coal mill, a medium-speed coal mill or a high-speed coal mill according to the coal type, boiler furnace type, load characteristics and other conditions.
Our company mainly produces medium-speed coal mills. The medium speed coal mill is a professional equipment for the preparation and processing of blast furnace ironmaking auxiliary materials. It is suitable for pulverizing and grinding of medium hardness materials such as bituminous coal and lean coal. This machine can provide suitable auxiliary materials (pulverized coal) for blast furnace ironmaking system. GBM medium speed coal mill-vertical mill has low power consumption and high efficiency. The material is ground by the principle of material layer grinding. Low energy consumption. The power consumption of the grinding system is 20-30% lower than that of the ball mill.
