The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized ...

The oxygen plant can improve conditions by reducing the explosion hazard in the coal mill but increases risk by mixing high purity oxygen with fuels and potentially operating the kiln shell at elevated temperatures. Components operating at elevated temperatures tend to increase safety hazards for workers.
