These are then grounded to fine powder in the tube mill and mixed in desired proportions to get raw mix. Raw mix is stored in storage bins silos and kept ready to fed into a rotary kiln.Jun 16, 2008 For most portland cement plants, the levels of sulfur in raw materials are low enough that most of the SO 2 generated is removed by the natural scrubbing action of the kiln raw feed. However, in those instances where the sulfur content of raw materials is great due to the presence of pyritic sulfur, uncontrolled SO 2 emissions can be significant.
