Abstract
The article deals with the problem of complex processing of technogenic anisotropic materials. The direction of production activity, which requires the creation of special equipment for selective exposure at each stage of the technological process, is determined. A description of the devices of aggregates that have a basic crank-slide scheme of the mechanism for performing various technological functions is presented: grinding, classification, thin and ultrafine grinding, homogenization, agglomeration, etc. A brief description of patent-protected designs of vibro-centrifugal units is given: centrifugal grinding and mixing unit, centrifugal unit with parallel grinding blocks, vibration-centrifugal granulator, vibro-centrifugal unit of combined action. The design features of the vibro-centrifugal unit of combined action intended for complex processing of technogenic fibrous materials in two ways are considered. One of the developed technological options for the implementation of the vibration-centrifugal combined effect on the material is described in detail, in which, according to the single-branch variant, the processes of deagglomeration of technogenic fibrous materials in the first chamber, grinding and mixing of the components of the composite mixture in the second chamber and micro-granulation of the mixture with fiber fillers in the third the camera. The results of the analysis of the kinematic scheme of the basic crank-slide mechanism are presented and a system of equations for determining the position functions of the points of the mechanism links is obtained, the characteristics of speed and power parameters in individual units of the unit are defined. Taking into account the identified advantages of the vibro-centrifugal unit, the directions of its use for complex processing of technogenic materials are determined.

Summary
С целью установления рациональных соотношений длин звеньев рычажного механизма введем коэффициент относительной длины шатуна ν=. Проводим кинематический расчет ВЦА с определением величины перемещений, скоростей и ускорений центров звеньев. Исходными данными для кинематических расчетов являются конструктивные параметры экспериментального образца ВЦА, для которого величина эксцентриситета вала е = 0,02 м; коэффициент смещения средней камеры = 0,5; коэффициент относительной длины шатуна = 33. Проведенный нами кинематический расчет параметров агрегата позволил определить характер скоростных и силовых параметров в отдельных узлах агрегата для расчета потребляемой мощности привода ВЦА. Рассматривались условия действия силовых нагрузок на кинематические звенья и узлы ВЦА для дезагломерации ТВМ и гранулообразования композиционной смеси ВЦА, в котором при одноветьевом варианте реализуются последовательно процессы дезагломерации ТВМ в первой камере, измельчение и смешение компонентов композиционной смеси во второй камере и микрогранулирование смеси с фибронаполнителями в третьей камере. На ползуны верхней камеры дезагломерации А: силы тяжести камеры дезагломерации и ее рабочих элементов ; сила нормального давления ползунов на направляющие камеры дезагломерации и сила инерции u 01у верхней камеры
