refractory brick in rotary kiln cylinder‚it is not convenient to maintain rotary kiln and keep rotary kiln safe operation. When the kiln temperature reaches a certain degree‚ cement rotary kiln generates melt and fly ash in the clinker‚ chemical adsorption and physical adhesion on the surface of refractory brick‚which is increasing raise on the weight and the tensile stress is also growing‚ once the tensile stress is too large‚rotary kiln cylinder deformation will be enlarged.therefore we should pay

It has been found exopolymeric substance are involved in precipitation of CaCO3. Bacterial cell walls and exopolymers exuded by bacteria serve as an important site for adsorption of ions‚ mineral nucleation and growth [1‚ 2].These biopolymers have been found to play important role in morphology as well as mineralogy of carbonate precipitates [3]. Kawaguchi and Decho [4] reported that matrix of extracellular polymeric secretions
