Cement milling is the process of grinding together cement clinker, gypsum and other additives to produce a fine grey powder. The resulting material, called "cement meal", is then heated in a rotary kiln to around 2,000°F to produce the finished product known as Portland cement, which can be used for many different construction purposes.

The hot clinker from kiln discharge is cooled very quickly/ quenched in air with the help of efficient coolers. The temperature of clinker is brought to 50oC from 1400oC. Fast cooling is very essential to get good quality clinker . ... Clinker and gypsum are pre crushed in a Roller press and subsequently fed into Cement mill for fine grinding ...

As the grinding time in the mill increases, the fineness of the material is increased. This is because the balls in the mill get more time to grind the clinker. Any unwanted or coarse clinker is ground to fine state in the mill. It was observed that as the clinker is subjected to grinding for relatively longer time, Blaine quality improves.

Grinding Aids reduce particle re-agglomeration during and after the milling process so improving the yield. Strength enhancers push clinker reactivity increasing the use of SCM in blended cements.

Furthermore, Adbri and Cockburn Cement are currently upgrading the Kwinana Bulk Terminal with a slag feed system and modern ball mill circuit with two cement mills for grinding slag and clinker. The AUD199m project …

An early approach to grinding was the use of a short tumbling mill to break the large clinker down to the size of grit and then a long tube mill to grind the grit down to powder. The next ...

Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.

The Tovarov grindability index is used to determine the influence of materials on the cement clinker grinding capacity of a mill; the basis is rotary kiln clinker with a defined grindability index of a = 1.
