Abstract

The process of particle attrition in an apparatus with a fluidized bed of material has been investigated. A mathematical model of the process of particle attrition was proposed, which makes it possible to determine the density of the distribution function of particles by weight, as well as the degree of attrition depending on the average residence time in the bed. An experimental study of the particle attrition was carried out on the example of granules of ammonium sulfate in an apparatus with a spouted bed and the adequacy of the proposed model to the actual process was confirmed.

流化床设备中颗粒的磨损

摘要

已经研究了在具有材料流化床的设备中进行颗粒磨损的过程。提出了颗粒磨损过程的数学模型，该模型可以确定颗粒按重量分布函数的密度以及取决于床中平均停留时间的磨损程度。以硫酸铵颗粒为例，在带有喷嘴床的装置中进行了颗粒磨损的实验研究，证实了所提出模型对实际工艺的充分性。
