【摘要】 通过流化床内颗粒磨损实验，探讨了磨损率随床重、气速及时间的变化关系，并对磨损前后物料粒径分布进行了对比，推断出颗粒的磨损机制．更多还原

【Abstract】 This paper discusses the relation of the wearing rate to bed weight, air rate,wearing time by the wearing experiment of particle in fluidized bed. And the wearing mechanism of particle has been inferred by contrasting the particle distribution before wearing with the particle diameter distribution after wearing.更多还原
