Clinker microstructure has been widely studied through numerous microscopic methods, including petrographic thin sections and the "Ono" method. However, these techniques have limitations in the general understanding of clinker characteristics, and often it is difficult to compare the quality of clinkers from different sources using …
The development of clinker coolers in recent times has been guided by market demands for maximised availability, reduced maintenance and rapid conversion with minimum production downtime, accompanied by the over-arching requirements to reduce energy consumption and minimise the impact on the environment. thyssenkrupp has …
Clinker: reactions in the kiln The milled and blended raw materials go to a silo and then to the kiln. Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials - temperatures up to about 1300 °C.

The Micromill is Alcoa's proprietary technology that manufactures the most advanced aluminium sheet on the market, according to Alcoa. Since being introduced in December 2014, Alcoa has achieved some significant breakthroughs, producing more formable aluminium sheet, with greater strength, lighter weight and higher formability.
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.
Today, thanks to Danieli "Micromill" - a Minimill based on ultra-compact design and extremely low transformation costs - it is possible to produce 250-300,000 tpy of long products with an overall investment per ton typical of a 1.0-1.5 Mtpy Minimill.

The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.

Clinker liquid and nodule formation Above about 1300 °C the proportion of liquid starts to increase - by 1450 °C, perhaps 20-30% of the mix is liquid. The liquid forms from melting ferrite and aluminate phases and some belite. The liquid content is more than the sum of the aluminate and ferrite phases in the cooled clinker because of the ...

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...
