Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

The slack coal is often used as combustion agent in steel company, thermal power plant, etc. The consumption of coal is quite large in thermal power plants. Take a 1 million kW thermal power plant for example, coal consumption amounts to 11,000- 13000t a day, which takes 60% ~ 80% of the cost for generating electricity.

The conversion of this coal to the end goal of electricity is a multi-faceted process: The coal must be unloaded from the train. Traditional ways of doing this require the use of cranes picking up the coal from the cars, however newer plants have the floor underneath the train tracks drop away, allowing the coal to be dropped into underground containment.
