To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas, and recycled waste streams, heat the raw materials as they swirl through the cyclones.
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.
