The cement kiln

The purpose of a cooler is, obviously, to cool the clinker. This is important for a several reasons: From an engineering viewpoint, cooling is necessary to prevent damage to clinker handling equipment such as conveyors. From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.

CLINKER GRINDING IN CEMENT PRODUCTION

 · Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

What is the purpose of adding gypsum in cement?

What is the purpose of adding gypsum in cement? Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.

 · The C 3 S that forms in a cement clinker contains about 3-4% of oxides other than CaO and SiO 2. Strictly speaking, this mineral should therefore be called alite rather than C 3 S. In a typical clinker the C 3 S would contain about 1 wt% each of MgO, Al 2 O 3, and Fe 2 O 3, along with much smaller amounts of Na 2 O, K 2 O, P 2 O 5, and SO 3 ...

Cement Kilns: Grate Coolers

The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling air is roughly at right angles to the direction of movement of the clinker, and the cooler functions as a cross-current heat exchanger. This mechanism is inherently less efficient than a counter-current heat ...
