| Research Abstract |
Measuring method of a sink velocity of an object in a gas-solid fluidized bed was newly designed, and the effect of the bed height on the velocity was investigated. It was found that the height should be lower in order to get the stable velocity. Using this result, a thickener-type gas-solid fluidized bed separator was newly designed and made, and a separation speed was examined. The speed of this separator was 2.4-3.4 times larger than that of previous one. From this result, it is suggested that this thickener-type system is effective for improvement of the speed.
