Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
These clinkers are cooled and grounded into a fine gray powder. To extend the cement's setting time, small amount of gypsum is added during this process as this powder makes its way through the mill's two chambers. This is now the finished product and is called Portland cement or simply cement.

Portland cement is manufactured by crushing, milling, and blending selected raw materials containing appropriate proportions of lime, iron, silica, and alumina. Most Portland cement particles are less than 0.045 mm (No. 325 sieve) in diameter. Portland cement combined with water forms the cement paste component of the concrete mixture.
· At 7.6% of world cement production, the cement industry in Europe represents around 56,000 direct jobs. The average cement plant will produce around 1 million tonnes of cement per annum and cost around €150 million. Advances in automation mean that a modern plant is usually manned by less than 150 people (CEMBUREAU, 2012).
Cement Mill UNIVERSAL DRIVE BALL MILLS UDCM type mills are designed to achieve maximum grinding efficiency, low energy consumption, compact plant layout and compact mill drive design.
The heart of the portland cement manufacturing process is the pyroprocessing system. This system transforms the raw mix into clinkers, which are gray, glass-hard, spherically shaped nodules that range from 0.32 to 5.1 centimeters (cm) (0.125 to 2.0 inches [in.]) in diameter.

The Plant The McInnis Cement plant in Port-Daniel–Gascons is a major industrial complex in Canada. More than $1 billion was invested in the plant and network of terminals. Our plant is a model of environmental performance and meets or exceeds the highest standards in the world.
These differences between cement grinding and grinding of raw materials made it a serious challenge to obtain a good performance of a vertical roller mill in cement grinding. Today, however, the OK mill has become an excellent example of a mill design that has overcome the difficult grinding conditions associated with finish
blend of Portland Pozzolana Cement under the brand name Jaypee Cement (PPC) and Ordinary Portland Cement brand name Jaypee Cement (OPC). Its cement division has currently operates modern, computerized process control system, Jaypee Sidhi cement plant (JSCP) and with an aggregate capacity of 3.5 MTPA Cement production.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
However, the water must then be removed by evaporation as the first step in the burning process, which requires additional energy. The wet process, which was once standard, has now been rendered obsolete by the development of efficient dry grinding equipment, and all modern cement plants …
as a supplemental fuel to coal. Only one California plant utilizes gas as a primary kiln fuel. This is a relatively small plant that produces white cement. The remainder of the natural gas usage is associated with boiler and machine drive end uses. Figure 2-1 Cement Industry End Use Electricity Consumption Process Machine Drive 81% Process ...

(Lanka) which will be used in the harbour area of Galle on the southern tip of Sri Lanka as part of an expansion of the Ruhunu cement plant.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
History. Phoenix Cement Company is a regional supplier of portland cements, gypsum, and fly ash products. Based in Phoenix, Arizona, the company began operating in 1959 when American Cement Corporation constructed a plant in Clarkdale, about 100 miles north of Phoenix.
