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. However, the effects

The fineness of cement is usually monitored by measuring the specific surface area (Blaine) or a sieve residue of the product. However, the effects

The cement mill

In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.

Advanced process control for the cement industry

An inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the FL ball mill is proven to do just that.

better cement quality. SikaGrind® allows producers to economically achieve the desired fineness and quality of cement! ́ SikaGrind® ensures that the particles stay separated, thus enabling suffici-ently fine particles to leave the mill and creating space for coarse particles to be refined. ́ Using grinding aids reduces the

Cement fineness. Closed circuit cement mill | by A.Sen ...

Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
