In order to meet the demand of blast furnace injection, it needs to change lump coal into powered coal which size is under 75um. Because pulverized coal is explosive and flammable, safety requirements need to be stricter in the grinding process. Therefore, online monitoring system is required for the grinding process to ensure production safety during the preparation of coal.
