The grinding process differs depending on the pyro-processing process used. The feed to the kiln is called “raw meal.” Clinker is produced by pyro-processing the raw meal. The raw meal is burned at high temperatures, first by calcination of the materials and then by clinkerization to produce clinker. Various kiln types have been used historically or are used around the world.
A method of grinding cement clinkers by use of a cement clinker grinding apparatus, said method comprising: supplying feed material to be ground on a central area of a table of a vertical roller mill, said vertical roller mill having said table for rotating about a vertical axis and a plurality of rollers arranged on said table at circumferential intervals in a rotating direction of said table;
