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 capable of making a system that conforms to these and is therefore safe.

For example, in a direct fired coal mill system if the moisture content of the coal drops, the kiln will get more tons of dry coal at the same setting on the raw coal feeder. Changes in the percentages of coal versus coke, for a kiln firing both fuels simultaneously, will also affect the CO and O2 level.
01 March 2016. Coal provides around 90% of the energy consumed by cement plants around the world, despite the environmental harm caused by its combustion. It takes …
The utilisation of coal in the cement and concrete industries takes three basic forms: 1. As a fuel in the production of cement clinker, 2. Ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds, 3. Ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.
