Due to ever increasing fuel costs the target was to change the plants operation from import coal with 25 % volatiles to local lignite coal with up to 40 % volatile matters and a moisture content of up to 20 %. For this reason the coal mill had to be modified form cooler middle air to pre-heater exhaust gas operation.
This publication deals with the difficulties which designers of coal mill plants for cement production face, when they agree to refer to existing guides and codes. It also aims to offer guidance for clearer understanding of the warnings given in the codes, by putting them into context and relating them to practice with the help of examples.
