亜鉛精鉱流動層の粘性と不純物の許容限

抄録

As the fluid-solid systems possess property similar to that of: viscosity in liquid, which will markedly influence their flow characteristics, the viscosity concept may be readily appiled to the prediction of the condition under which the roasting of ores will be difficult. Accordingly, a study has been made of the viscosity of the fluosolid roasting systems with zinc ore mixed with some copper and lead ores as impurities.
From the results, it was found that the tendency of fluidized bed to lose stability increases as its viscosity increases, and the impurity limit which affects upon stability of the bed was obtained.
