Cement Clinker

In the manufacture of Portland cement, clinker is the solid material produced by the cement kiln stage that has sintered into lumps or nodules, typically of diameter 3-25 mm. Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality.

Cement is obtained by grinding the clinker and gypsum in a mill. Often a high quality limestone is added to the cement, and this can improve the performance of the cement in the final concrete. Flyash (ash produced from coal fired power stations) and Steel slag are also often added to the cement in the grinding process.

The breakdown of the minerals during this process makes the resulting clinker a highly abrasive bulk material. The high heat of the material coming out of the kiln, coupled with the subsequent cooling of the clinker, adds further complexity to the design of the drag chain conveyors at this stage in the cement manufacturing process.
