it at up to a 45˚ slope to the top of the clinker store without intermediate transfer. In combination with cement storage, there should be adequate storage capacity for clinker and other cement components to maintain deliveries during maintenance shutdowns and, if the market is cyclical, to bridge low and high shipping periods.

What is Cement Clinker? Composition, Types & Uses

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400 C-1500 C in the rotary kiln.

Definition of portland cement - American Concrete Institute

Definition of portland cement. Q. What is portland cement? A. Portland cement is the product obtained by pulverizing clinker, consisting of hydraulic calcium silicates to which some calcium sulfate has usually been provided as an interground addition. When first made and used in the early 19th century in England, it was termed portland cement because its hydration product

Clinkerization - Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.

clinker factor - Page 1 of 2 - International Cement Review

Nov 10, 2010 Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and 100%. This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix.
