In the raw mill, raw materials are blended and ground into particles of a desired size. The final output from the raw mill is denoted as raw meal. Finally, a conveyor belt trans- ports the output raw meal to a homogenization silo. The quality standards of the raw meal are determined by the oxide composition of the raw meal.
