The raw mix is fed into a circular storage unit called a raw mix storage Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
Russian national standard (edition 2015) is applicable to the grinding balls manufactured by rolling and forging method and used for grinding the raw materials in ball mills. This document describes the requirements for raw materials and finished products (grinding balls); classification of grinding balls by groups of hardness and requirements; regulates the rules of labelling, packaging ...
Grinding materials processing Britannica. In cement: Crushing and grinding containing a charge of steel grinding balls. This grinding is done wet or dry, depending on the process in use, but for dry grinding the raw materials first may need to be dried in cylindrical, rotary dryers.
Drying of moisture in raw materials is required for effective grinding and subsequent handling of raw meal. This is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 320°C.

Storage Guidance Q7 A(7.4) Receipt of Raw materials: Upon receipt, the inspection of incoming raw materials is an essential step. Inspection ensures that the correct raw material which meets the quality specifications has been received.
The first objective of the course is to give an overview of the process chain within the cement industry. All the main processes involved during cement production will be discussed, including the extraction and processing of raw materials, the combustion process, cement grinding, quality control, and storage, as well as the distribution of cement.
Raw materials should arrive in good condition and in sacks which have not been used for the storage of fertilizer, pesticides or chemicals. Raw materials will vary from country to country and from region to region and will have widely ranging bulk densities (weight for a given volume).
First, the design of the raw material grinding and batching station should meet the following requirements: (1) The capacity of the batching bin should meet the needs of raw material grinding production. When using the storage batching ingredients, the storage capacity should be determined according to the storage requirements;
On initial receipt, raw materials should be labeled "Hold" or "Quarantine", and once they have passed QC testing, raw materials should be re-labeled "Released" or "Rejected". It is important that the storage location matches the status of the raw material. GMP requires that only "Released" raw materials may be used in production. Storage:

And despite the extra grinding, raw material fineness never again achieved the high standard achieved in the sedimentation process. Furthermore, there was distinctly less homogenisation effect in the new process - slurry was commonly pumped direct from the mill system to the drying floors without any intermediate storage or blending.
