Assessment of Residue Floating-Sinking and Separation We fluidized powders at prescribed superficial air velocities u0/umf. When using uni-beads we separately added plastic, rubber, and wiring; with zircon sand we added the three constituents together; and with glass beads we added plastic and rubber together. When using uni-beads we added the three constituents together at the u0/umf at which plastic and rubber best floated, and wire harnesses best sank. We stopped the air one minute after adding the residue constituents, measured the distance from the bed bottom to each constituent’s center of gravity i, and determined the weight percentage wi of each constituent at each 3-cm stratum from the bed bottom. To assess separation, we determined the purity xp and recovery rate xr, defined below. In uni-beads and zircon sand, plastic and rubber floated while wiring sank. Hence the values of xp were the weight percentage of plastic and rubber in the dust that floated in the top stratum at i12 to 15, and the weight percentage of wiring in the dust that sank to the bottom stratum at i0 to 3. For xr values we used the weight percentage of the portion of total plastic and rubber that floated in the top stratum at i12 to 15, and the weight percentage of the portion of total wiring that sank to the bottom stratum at i0 to 3. In glass beads plastic floated and rubber sank. Thus for their xp values we used the weight percentage of dust plastic that floated in the top stratum at i12 to 15, and the weight percentage of dust rubber that sank to the bottom stratum at i0 to 3. For xr values we used the weight percentage of the portion of total plastic that floated in the top stratum at i12 to 15, and the weight percentage of the portion of total rubber that sank to the bottom stratum at i0 to 3. The experiment was performed three times under each set of conditions, and the average and standard deviation of each value were determined. [ Last edited by xinyi8853 on 2010-10-10 at 18:29 ] |
