blending and grinding in cement process

Cement production will experience several procedures which include raw materials blending process and burning process, cement clinker grinding process, and packaging process. Cement raw material and cement clinkers mainly contain four oxides: calcium oxide or lime (CaO), silica (SiO 2 ), alumina (Al 2 O 3 ), and iron oxide (Fe 2 O 3 ).

Homogenization (BLENDING) Cement Plant Optimization

For cement plants of small capacities where preblending by staking-reclaiming was not a necessity, batch type blending (Air merge-turbulent blending) to achieve a blending ratio of 10-1 was enough to produce a consistent kiln feed. However, as the plant capacities grew bigger and bigger, Batch type silos to contain a buffer stock of 2-3 days (kiln feed) became unfeasible and
