Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.
Cement is one of the most used building materials in the world. The process of cement production involves numerous and complex reactions that occur under different temperatures. Thus, there is great interest in the optimization of cement manufacturing. Clinker production is one of the main steps of cement production and it occurs inside the kiln.

Clinker rapidly burned at the minimum temperature for combination, then rapidly cooled, contains small, defective crystals that grind easily. These crystals are usually also optimal for reactivity. On the other hand, long burning at excess temperature, and slow cooling, lead to large, well-formed crystals that are hard to grind and un-reactive.
AM signifies the temperature at which liquid formation starts, the nature of liquid formed and the colour of clinker formed. The lowest temperature is obtained ai AM equal to 1.6, which is the optimum for clinker formation and nodulization. Higher the AM, lighter the colour of clinker (cement.
Clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. The composition of clinker, such as free lime, has to be closely monitored to ensure the quality of the cement.
a peak temperature of 1450-1500°C (Taylor, 1997). The chemical reactions taking place in the kiln form new minerals which make up clinker and give cement and concrete the properties of adhesiveness and strength desired in construction. An illustration of clinker crystalline components identified by cement chemists' notation
sulfates usually remain with the clinker. • In the upper transition zone, sulfates become relatively more stable. • The calcining zone has optimum conditions for the capture of SO2. • In the preheat and drying zones, SO2 capture is slower. • In-line raw mills, despite their low operating temperature.
heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of ...
Dec 01, 2017· The ball mill has two rotating chambers with ceramic balls that grind the clinkers. The clinkers are fed from one side. The mill is heated at various temperatures along the separator. The temperature evaporates the water in the clinker and initiates various chemical reactions within the .

Jun 10, 2010· However, if you are adding limestone as a filler in your cement, there is a solution to using partially weathered clinker without any drop in mortar strengths, as long as the L.O.I. of the weathered clinker is not greater than the contribution of the normal limestone filler content. For example, if your GP cement normally contains say 5% of ...
