Cement Kilns: Size Reduction and Grinding
In the kiln, the finely-divided rawmix is sintered, resulting in production of hard clinker of typical size 1-50 mm. In order to produce cement, this has to be ground, again to a powder of maximum size about 100 μm. In addition, other process streams are involved. When the kiln is fired with solid fuel, this will typically be received in a size range 10-50 mm, and must be reduced to below 200
