Abstract
The mechanism of surface interactions of polydisperse particles during agglomeration is considered. The characteristic of fibrous materials is given on the example of shredded waste paper and cardboard. An equation is obtained for calculating the soaring speed of the particles of the fibrous structure depending on their relative sizes and density. The mechanisms of coagulation of particles in moving air streams are considered. The prevailing role of coagulation due to the acceleration mechanism for fibrous materials is shown. The results of the calculation of the dynamics of particle enlargement of technogenic fibrous materials depending on their initial size are presented. The expediency of organizing the process of agglomeration of particles in the toroidal chambers of a pneumomechanical apparatus under the action of centrifugal forces is shown.

Summary
О РОЛИ ПОВЕРХНОСТНЫХ ВЗАИМОДЕЙСТВИЙ ЧАСТИЦ ВОЛОКНИСТОЙ СТРУКТУРЫ ПРИ АГЛОМЕРАЦИИ В ВОЗДУШНОМ ПОТОКЕ Показана преобладающая роль коагуляции за счет механизма ускорения для волокнистых материалов. Представлены результаты расчета динамики укрупнения частиц техногенных волокнистых материалов в зависимости от их первоначального размера.
