Research progress on fluidized particle attrition
摘要
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.关键词
