Kiln Floating Page 1 of 2 International Cement Review
Dec 11, 2010 · Re: Kiln Floating. Hello Bandari. When kiln rotates such that downhill thrust roller is only engaged for a partial revolution and all rollers are correctly skewed than we can say the kiln is floating . the thrust tire will always have a slide ammount of wobble, While a thrust roller is in contact that causes the kiln to be pushed uphill for part of rotation, As the wobble then moves away

Use Of Alternative Fuels In The Cement Industry PEC
The main advantages of using Alternative Fuels in the Cement Industry are economic and environmental. Cement producers strive to reduce their production costs. Fuel accounts for 20 to 25% of the production cost of cement and one viable option is the use of alternative fuels at a much lower cost than conventional fossil fuels.
Siam City Cement Public Company Limited. in 1989 the company became the first cement producer in Southeast Asia to introduce a waste heat recovery system which converted heat captured from the cement kiln to produce electricity. This makes SCCC the first Company in the Thai cement industry awarded with Green Industry Level 5
