Prehomogenisation is used primarily for the main components in cement production, i.e. limestone and clay. With the increasing variation in the grades of coal used for coal firing installations, there is a growing need for prehomogenisation and storage of coal. Depending on the properties of the coal used, a prehomogenising or buffer store is used.
