Abstract: Recent progress of fluidized particle attrition was reviewed on testing apparatus，attrition mechanism and kinetic models. Compared with the single-particle tests，the multi-particle tests are closer to the industry process. Attrition can be divided into two main types：fragmentation and abrasion. The growth of the laboratory-scale fluidized bed and the kinetic models were mainly introduced. The time-dependent behavior of particle attrition was the basis of discussing particle attrition. The present time-dependent models were piecewise functions which failed to unify the initial and steady stages of attrition，and other models focused on describing the effects of air velocities and the structures of fluidized bed on attrition rate. The effects of the time-dependent behavior，particle properties and the characteristic of bubble should be investigated in order to meet the needs of further exploration of attrition mechanism and high attrition resistance particles.

摘要： 介绍了近年来流化磨损测试设备、流化磨损机理以及流化磨损动力学模型等3个方面的研究进展；通过比较单颗粒测试体系和多颗粒测试体系，阐明了多颗粒测试体系更接近工业流化磨损过程，并且介绍了实验室流化床测试设备的发展；概括了颗粒流化磨损的两种典型机理：表面磨损和体相断裂。综述了现有的流化磨损动力学模型，指出了流化磨损时变规律是研究颗粒流化磨损的基础，目前的时变规律模型是分段函数的形式，未能把流化磨损的起始阶段和平衡阶段统一起来；其他磨损模型致力于描述流化气速和流化床结构与磨损速率的关系。指出今后需在时变规律、颗粒性质和鼓泡特征等方面加强对流化磨损的研究，以满足完善流化磨损机理和开发高耐磨损性颗粒材料的需要。
