important features here are: • no metallic contact between the grinding parts, even when the mill is empty; thus no sparking • individual guidance of the grinding rollers ensures low-vibration mill operation even in the partial-load range down to 20 % • the hydropneumatic counter pressure system makes it possible to grind a multitude of
ContactJan 17, 2022To meet the market demand for FGD limestone powder in power plants, Fote has developed a variety of limestone grinders. The most popular dry grinders are Raymond mills and ultra-fine mills, and the most favorable wet grinders are ball mills. Outsorced Limestone Powder for FGD

ContactAlmost one year is required in the pre-construction phase of FGD. Further, 30 months period is required for construction of FGD after the LOA. Hence, total of 3.5 years.
ContactAn alternative option is for the limestone to be milled off-site (dry VRM circuit at the limestone mine) so that the dry, milled limestone is delivered to site without further grinding and/or processing required. This could result in a significantly reduced CAPEX and OPEX for the FGD process at any coal-fired power plant.
ContactA pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of 39.2% was observed for the dry VRM compared to the wet ball mill (37.7% for the circuit).
