Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.

Coal Mill. Powdered coal is typically used to provide the controlled heat within the burning zone of the rotary kiln. As part of essential fire prevention measures, carbon monoxide (CO) levels must be monitored at the coal mill where pulverisation takes place. When coal is in contact with air it oxidises to form CO and carbon dioxide.
