importance of vertical mills in the modern cement production

The purpose of the mill system is to provide a fineness to the product that will result in the required reactivity and consequently the strength producing potential of the product – the cement. The fineness of cement is usually monitored by measuring the specific surface area (Blaine) or a sieve residue of the product.

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4 .2H 2 O).

2,000 cement production plants in operation across the globe in more than 160 countries; this is in addition to 500+ clinker grinding facilities. The predicted global growth of consumption of cement is estimated at around 4.5%, year on year, in relation to the present global cement production capacity which is more than 4 billion tons per annum.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

before passing the cement mill. During finish milling, the clinker is ground with other materials (for special finished product characteristics) into a fine powder. Many plants use a roller press to pregrind the clinker and the gypsum. These materials are sent through ball or vertical mills which perform the remaining grinding. The

Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.
