The introduction of alternative fuels (AFs) in a cement plant can often provide a good opportunity to improve fire and explosion protection systems. The availability of specialised knowledge is key to the successful completion of these projects.

Users of coal grinding systems are often unaware that they operate equipment that is not correctly protected against fire and dust explosions (see Figure 1). During its fire and explosion protection evaluations in coal mills worldwide, Coal Mill Safety Pte Ltd has found the issue to be widespread, applying to larger and smaller cement producers, including those covered by ISO 9001 or similar QM certification. The issue spans the entire spectrum, from minor to major faults in protection, including non-existent protection. It is often the result of a lack of specialist knowledge by system suppliers, operators, certifiers and insurers, which then leads to a lack of hazard awareness. However, the number of fire or explosion- related incidents and the damage they inflict remains under the limit that would lead cement producers and their insurers to take corrective action. Therefore, this situation continues to exist.
How to get your coal grinding system correctly protected? You will be surprised about what has gone wrong with fire and explosion protection of your system(s). Be sure about that! Evaluation of a coal grinding system’s fire and explosion protection, including the raw coal storage and the fine coal silo storage normally can be done in one day, mostly without having to stop coal grinding.
The evaluation will be done by way of touring the plant, making photos and having interviews with the people responsible for the operation. This will result in a comprehensive illustrated report and complete recommendations with explanations for necessary corrections. Ask for a free-of-charge offer indicating your airport.
