Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
Technology principles: Clinker is the main active ingredient in cement, and producing it is the most emissionsintensive step of cement production. Alternative constituents are materials that can replace a portion of it while conserving the required performance properties of the cement.
Cement Grinding. The principle of Grate Discharge grinding is nearly universally adapted in the cement grinding industry. Grate Discharge Ball Mills are the rule rather than the exception. Rod Mills for raw and finish grinding begin to enter the picture. Larger and larger .
Abstract: Cement is one of the strategic commodities that supporting acceleration of infrastructure development and economic growth. It forces the cement companies to improve the production process to be more effective and efficient.

Clinker production is the most energyintensive stage in cement production, accounting for over 90% of total industry energy use, and virtually all of the fuel use. Fuel use for clinker production in a wet kiln can vary between and MBtu/short ton clinker (Worrell and Galitsky, 2004).
Cement manufacturing is an energyintensive process due to the high temperatures required in the kilns for clinkerization. The use of alternative fuels to replace conventional fuels, in particular coal, is a widespread practice and can contribute to improving the global warming impact and total environmental footprint of the cement industry.
† Although the two words "cement" and "concrete" are sometimes used interchangeably, cement is actually one of the ingredients in concrete. Cement is the fine gray powder that, in combination with water, binds sand and gravel or crushed stone into the rocklike mass know as concrete.

The Australian Government's Clean Energy Future Policy only covers approximately 60 per cent of Australian emissions. This means Australian cement manufacturers, and other industries included in Australia's climate change policy, have to carry an unfair burden. 4. Climate change policy directed at Australian industry should be singular in nature.
The Enduron® DW dewatering screen is a light weight dewatering screen. Well suited for applications in the sand and aggregates, and mining and minerals processing industries, the screen's lower capital and operating cost is a result of its light weight design.
The important general principles in coprocessing are : 1. Additional emissions and negative impacts on human health must be avoided 2. The quality of the clinker/cement must remain unchanged. 3. Companies that co process must be qualified • Assure compliance with all laws and regulations
