Coal Mill Process Safety

Jan 19, 2021

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is 100% capable of making a system that conforms to these and is therefore safe. However, this is not the case

    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
