According to the classifing method of Geldart,ultrafine powders belong to group C particles.It is difficult to fluidize because of such cohesiveness.However,it was discovered recently that some powders can be fluidized smoothly through forming larger agglomerates at high gas velocity,and the fluidization quality of some powders can be improved by external force.

按Geldart的分类法，超细粉属难流化的C类颗粒，但近年来的研究表明，某些超细粉在高气速下可以形成较大的聚团，而以聚团形式实现平稳流化；对在高气速下难以流化的超细粉，人们通过引入外力场等方法来改善其团聚特性，提高流化质量。

The results show that the fluidization characteristics of scrap printed circuit board particles depend on the average size and type of particles. The scrap printed circuit boards particles, belonging to Geldart A group with strong viscous force, whose fluidization was similar to fluidization of Geldart C, was difficult to fluidize. Whereas, the scrap printed circuit board particles belonging to Geldart B can be fluidized smoothly.

实验结果表明，电路板塑料颗粒为Geldart A类颗粒时，粘性力大，塌落特性明显，流化性能较差，具有拟C类颗粒的流化特性；电路板塑料颗粒为B类颗粒时，塌落特征不明显，并且随着粒径的增大，最小流化速度也增大。

The agglomerations sizes of fine particles in the fluidized bed are smaller under higher SPL. The sound waves have little effect on the agglomerations when it is under 120dB. But the agglomerations sizes will be dramatically reduced to 180μm from 720μm when the SPL is above 130dB. The umf has a minimum value at an appropriate frequency of sound and a good quality of fluidization can exist in a greater ranges of frequency of sound when the SPL is higher.

当频率高于120Hz，流化床中形成聚团尺寸随着频率的增加而增大，最小流化速度也随着频率的增加而增大，当频率低于120Hz，流化床中形成聚团尺寸随着频率的减小而增大，最小流化速度也随着频率的减小而增大；料层越高，声波的衰减越大，超细颗粒的流化效果越差，最小流化速度越大。

The minimum fluidization velocity has a minimum value when the frequency of sound waves is 120Hz and it will decrease as the sound pressure level increases. The degree of sound attenuation will increase while bed material is higher and the fluidization quality of fine particles will become poor and the minimum fluidization velocity will increase. Compared with TiO2, the SiO2 fine particles have a better quality of fluidization at the same fluidized conditions.The cluster/subcluster model and oscillators model are used to describe the fluidization characteristics of fine particles in a sound-assisted fluidized bed. The theoretical calculations show that the minimum fluidization velocity umf is decreased with the SPL increased at the same frequency of sound and the quality of fluidization is better.

论文还系统的考察了声压和频率对纳米SiO2和TiO2颗粒流化特性的影响，结果表明：在频率一定的情况下，声压越高，流化床中形成的聚团尺寸越小，最小流化速度越低，流化质量越好；当声压低于120dB时，声场对超细颗粒流化特性的影响减小，当声压大于130dB时，则能显著改善流化效果，使流化床内的颗粒聚团明显减小，最小流化速度明显降低，粉体带出减小；声压一定，频率为120Hz左右时，最小流化速度最低，此时流化床中形成的聚团尺寸最小，流化效果最好；超细颗粒达到较好的流化状态存在一个最佳频率范围，随着声压增高，这个频率范围将增大。

The fluidization characteristics of ultrafine particles are reviewed and the agglomerating process is analyzed.

首先阐述了超细颗粒的流化特性(初始流化速度、床膨胀等)及团聚流化过程，然后重点对近年来国内外在改善粘性颗粒流化质量方面所作的研究工作进行了总结。

Research results indicate that X FLOUR has notable effects of fluidizing and water reducing.

研究结果表明：X粉具有显著的流化与减水效应，其流化与减水效果与目前市售掺合料的最高水平相当，明显好于硅灰。X粉与硅灰复合后，仍具有流化效应。X粉产生流化效应的机理，一是增加水泥浆悬浮体系的分散性；二是通过填充效应减少填隙水，增加了用于混凝土流动性的水量；三是增加混凝土混合料的浆体体积。X粉流化与减水效应的发挥，以与高效减水剂双掺为前提。

By introducing the concept of fluidizing extent factor, the fluidization technological parameters under different structure have a comparable factor.

在此研究中，由于不同结构参数时的物料流化工艺参数不同，通过引入流化程度因子概念，使不同结构下的物料流化工艺参数有了相同的可比因子。

In different conditions on fluidized state and stability of conical fluidized bed. The conlusions are: the conical angel of the conical fluidized bed is 20°, the fluidized state havesmall difference in conical distributor and distributor plate. The angle of conical bed increase,the fluidized state will have big difference. The angle is 60°and the conical as distributor, themass of fluidized is less, the most of material is the bottom of conical bed. The effect ofdistributor plate is much better than the conical distributor. Sawdust and rice hull can fluidize.The annular gap of conical distributor different, the angle of conical bed is same, the fluidizedquality of 10mm annular gap is better than the other conical distributors. The annular gap ismore wide, the conical bed have more slugging phenomenon and the pressure fluctuate is turnbig.In the experiment the flow of 2％and 4％distributor plates don\'t easy to control, becausethe pressure is very big and the pressure fluctuate of conical bed is too big.

在不同的条件下对锥形床的流化状态和稳定性进行了研究，结果得出：锥形床的锥角为20度时，分布锥和分布板的流化状态相差不明显，随着锥形床锥角的增大，分布锥和分布板的流化现象会出现明显的变化，锥形床锥角越大，分布锥的流化状态变化越明显，流化的的物料越少，大量物料都聚集在锥形床底部，而分布板在加料量少的情况下，能流化起来。10mm、15mm和20mm环隙分布锥在锥形床锥角相同条件下，10mm环隙分布锥的流化质量要好于其它两个分布锥，环隙越大越容易出现腾涌现象的产生，压降波动范围增大。2％、4％和6％开孔率分布板在本实验测定时，2％和4％开孔率分布板的流量不容易调节，同时产生的压降波动范围也很大，比较来说，6％开孔率分布板流化质量好些。
