3/3/2014Dears! I works for a cement plant it is trial-run now The impeller of the ID fan (temp of airduct about 360 Deg C) and the raw mil fan were made from material mark: 13CrMo4-5 ( Cr: 0 7-1 15% Mo: 0 4-0 6% wt ) I think they will be worn-out very fast Can anyone have idea! Thank you very much Best regard

9/1/2000ABB motors drives enable new cement plant process Inspiration and perspiration get the credit but most innovations become reality thanks to the right tools and available resources For instance a new semi-dry process is nearly doubling capacity at Lone Star Industries' cement plant (Greencastle Ind ) from 750 000 tons per year to 1 3

The ID fans are a major consumer of electrical energy and were previously controlled by sub-synchronous cascade converters which have a restricted operating range that limits the plant's production capacity Here the fan's speed was controlled in the range of 60 – 100 percent of their maximum but using the new drives solution they could

The original rotary cement kilns were called 'wet process' kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter It has to be long because a lot of water has to be evaporated
