Cement Kilns Size Reduction and Grinding

Rawmill systems typically require a feed of maximum size 510 cm so a crushing stage is first required In the kiln the finelydivided rawmix is sintered resulting in production of hard clinker of typical size 150 mm In order to produce cement this has to be ground again to a powder of maximum size about 100 μm Rawmill systems typically require a feed of maximum size 510 cm so a crushing stage is first required In the kiln the finelydivided rawmix is sintered resulting in production of hard clinker of typical size 150 mm In order to produce cement this has to be ground again to a powder of maximum size about 100 μm
