Raw meal homogenization occurs during the stage of raw meal preparation and involves a series of steps, including crushing, mixing, and grinding. By continuously mixing during storage and transport, the chemical composition of the raw meal is made uniform, ensuring consistent reactions during calcination and improving clinker quality.
