This document discusses coal dust explosions that can occur in cement plants. It outlines the key factors needed for a coal dust explosion: suspended coal dust above its flammable limit, oxygen, an ignition source, and confinement. It then discusses these factors in more detail, focusing on how coal properties, oxygen levels, potential ignition sources, and self

In discussion: Coal Mill Safety. 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.
