Cement Production | Cement | Howden

Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to be ground into the final product.

Process Compatible SO2 Control In Cement Kilns

The raw mill and preheater/precalciner use kiln exhaust gases to dry, heat and calcine the raw feed before it enters the kiln. The counter flow of raw materials and exhaust gases in the raw mill and preheater act as an inherent semi-dry (raw mill) and dry scrubber (preheater) to control SO 2 emissions. Some SO 2 may also be dry scrubbed in the baghouse particulate control system.
