The principles are exactly the same, and the feed rates will be quite similar However, the process and chemistry of the flue gas dictates when to use quicklime or hydrated lime If the system requires a lime slurry, the main way to determine if hydrated lime would be more suitable than quicklime is to know the amount that a given process requir...

Longwall mining allows for increased mineral extraction to occur, since it shears entire blocks of mineral onto a conveyor belt through the use of self-advancing, hydraulic roof supports or shields Once the mineral is extracted, the supports move on and the roof is allowed to collapse...
