Cement Production: Raw Meal Production in Steps

2. Raw meal production The crushed limestone is ground into raw meal. Additives such as clay, sand or iron ore result in the desired chemical composition. The MULTIDOS® H weighfeeders and MULTIDOS® VPD apron feeders feed the various materials into the raw mill accurately and reliably. The raw meal is then homogenised in the blending silos.
