Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coalfilled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, selfignition is a real possibility.

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.
