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.

Rawmill Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the

The raw meal is then stocked in special homogenization silos until it is fed to the rotary kiln. 3 . Clinker production 3 . In this stage the mixture of clinker and additives goes to the cement mill where all the components are ground until they achieve the ideal fineness, resulting in top quality cement.

MERCURY IN THE CEMENT INDUSTRY

Mercury emissions are typically higher in kiln operations with the raw mill-off (“direct” operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.

Re: Raw meal to clinker ratio. The true raw meal to clinker factor is given by: 1/(1 Loss on ignition of kiln feed). It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.
