The raw mix need to be ground up before sending to the process stage. A ball mill or vertical roller mill (VRM) are used for a grinding process. The raw mix is dried using the part of the excess heat from the kiln in this stage. Impact with attrition principles are used for grinding the raw materials using a ball mill.
