Significant amounts of silica dust occur as a by-product of certain construction processes. Over time this dust subjects rotating equipment, including Raw Mill fans, to high levels of erosion which ultimately reduces the plant rsquo 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 Tarmac face in their Dunbar plant. Over the past 12 years it has been performing to the highest of standards with only minimal outage repairs.
With an extensive installed base within the cement market, Howden has gained considerable process experience in plants throughout the world. We offer expert and unbiased advice that is about finding the right solution for each application. Contact Us Today. nbsp.

Fans for Cement Industry include the pre-heater exhaust kiln induced draught raw mill exhaust Cooler exhaust cooler forced draught and cement mill exhaust applications. Quality fans for complete dedusting applications air slide blowers and axial fans for the shell cooling are supplied by Reitz India. Reitz India has thousands of fan.
HAF Fan This robust highly efficient radial fan is designed to operate in demanding environments with efficiency above 80 Key benefits Fan efficiency up to 84 Designed for the harsh conditions of the cement industry Simple installationsingle suction type requires only one suction pipe connection Rigid support in elevated concrete.
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.
Feb 23 2016 · Raw mill exhaust fans Raw mill exhaust fans or stack fans are also called as de-dusting fans. In cement industry raw mill exhaust fans handle 2.2 ton of exhaust gases for the production of 1 ton.
Grinding Operation Objectives and KPIs: Highly energy intensive unit operation of size reduction in cement industry is intended to provide a homogeneous, dry ( lt 0.5 moisture) and super fine (10-20 residue on 90-micron sieve) raw meal powder for clinkerization process in kiln (Dry Process). Grinding operation is monitored for following parameters to ensure objectivity and economy of operation.
Chemical analysis of raw mix, generally on hourly basis. Product fineness (Residues) on 90-micron and 212-micron sieves. Feed moisture, and Product moisture, Production rate, tonnes hour Operating hours as run factor in Specific power consumption (SPC) kWh tonne.
Chemical analysis of +170 fraction to find separation factor (Done as and when required). The coarse (+170 ) fraction may be lime-rich or, more likely, silica-rich relative to the total sample but should show constant bias. Coarse particles should be limited to avoid burning problems: Silica gt 200μ Not more than 0.5 of KF 90-200μ Not more than 1.0 of KF 45μ Not more than 2.0 of KF Calcite gt 125μ Not more than 5.0 of KF.
Grindability and Power Consumption. Among various theories of comminution, most commonly accepted which is relevant to ball tube mills is Bond's theory, which states that power input in comminution process is proportional to the surface generated in the process and the grindability of the material. To measure grindability, Bond developed 'Bond's Work Index' (BWI), a 'test mill' and a testing procedure for WI. With the help of this we can work out power required to grind a material from a given feed size to a product of given fineness.
Other index known as 'Hardgrove Index" is also used to scale grindability of materials, particularly coal. Hardgrove index is commonly used to determine power requirements of vertical coal mills.
Wet Grinding: Open circuit Ball mill or closed circuit Ball mill Dry Grinding: Open circuit Ball mill, closed circuit Ball mill, vertical roller mill, Roll Press or Roll press in circuit with ball mill.
However, it would be seen that the most significant process and types used for raw material grinding operations in modern cement industry are:.

In the raw material process, raw materials such as silica, clay, and iron are finely pulverized by raw mill. In this process, fans and blowers for suctioning and collecting fine powder is used. Because of the large thermal effect of rapid temperature change inside the mill, we have designed fans and blowers taking this into consideration. When waste such as garbage and sludge is used as raw material, in some cases fans have corrosion resistance against corrosive components of the raw materials.
The process of heating crushed raw materials and making clinker, which is an intermediate product, consists of Kilning facilities, Cooling facilities centering on the preheater kiln. In the Kilning facilities, Cooling facilities, fans and blowers that have taken measures against abrasion and adhesion of raw materials and fans and blowers for reusing waste heat of the Kilning process are used respectively.
In the finishing process, the clinker is crushed by the finishing mill, and powder cement is produced. Here, a fan for suctioning and collecting the fine powder crushed by the finishing mill is used.
The dust collecting fan for cement factories is manufactured with extreme care so as not to cause any dust adhesion or damage due to corrosive components contained in the gas.
The Compagnie Belge de Ventilateurs S.A. ( CBV ) is manufacturer of tailor-made fans especially designed for the cement industry ( raw mill fan, preheater fan, bag house fan, cooler ESP fan, coal mill fan, booster fan, separator fan, cement mill fan amp clinker cooler fan ).
Years. Today, VSDs are used in a wide range of applications in the cement industry, such as Induced draft ID forced draft FD fans Baghouse fans Preheater tower fans Kiln gas fans Clinker cooler exhaust fans Separator fans Raw mills Cement.
