    In portland cement manufacturing, the raw materials are changed to clinker in the burning operation. Generally the rotary kiln is used for this purpose and involves many processes including pelletizing and nodulizing. This transformation is called clinkering and is analyzed as now generally practiced in cement making from the raw material to the resulting clinker
