Jan 22, 2016 Raw Mill Fans. Raw mill fan in cement industry carries gas and raw meal. The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. Induced Draft Fans.Steel Cement is building a UBE Vertical Roller Mill, Raw Material Storage and Handling Facility and a Finished Product Storage Silo to increase its ability to meet current and future demands. The purpose of this plant is to receive slag (which is a byproduct from hot rolling steel) via bulk cargo ships and process it into a valuable element.
Raw mill is basically use for the grinding process of the raw material supplied from stacker. Material from RMH crushes into the size of 90 micron (95 ) in a raw mill. Temperature inside raw mill is around 200 C to 250 C. Then fine material goes to the bending silo by using cyclone separator, classifier, raw mill fan, air slider and bucket.Over time this dust subjects rotating equipment, including Raw Mill fans, to high levels of erosion which ultimately reduces the plant’s output over time. At Tarmac (Dunbar, UK), their existing Raw Mill fan was replaced with an enhanced Howden design in 2007. This Howden fan was specifically designed to handle the high silica dust burden that.
Generally cooling fans are designed at 2.7 kg-air kg clinker.
