fluidized sand

基本解釋

A successful fluidized classification of quartz sand has been obtained on the basis of the analogy between classification and distillation.
本文是根據流態(tài)化分級與液體精餾類似性原理，采用流態(tài)化技術對石英砂顆粒進行了成功的分級。
The mixture can not fluidize when the percentage of quartz sand was below 60%. The quartz sand can fluidize very well alone in the fluidized bad.
當石英砂所占比例低于混合物的60%時，混合體系基本不能實現流化，而當石英砂單獨流化時，流化效果呈理想狀態(tài)；
Research on pressure drop for novel granular filter in fluidized bed using river sand and quartz sand as bed materials has been carried out. The results can be the base of the structure optimization.
介紹了在三維流化床顆粒層過濾器冷態(tài)試驗臺上采用黃砂和石英砂兩種床料進行試驗的初步結果，為新型流化床顆粒層過濾器過慮顆粒的優(yōu)化選擇提供參考依據。
