From the standpoint of ensuring the receipt of the recycled bodies for various technological purposes with standard and improved properties applicable in construction, petrochemistry, metallurgy and other areas of material production, recycling in the field of agglomeration of fibrous man-made materials is relevant. The article is devoted to the theoretical studies of the fibrous materials agglomeration characteristics in flat-matrix granulators-extruders with the channels of variable circular cross-section. Taking into account the analysis of the well-known calculation methods and as a result of the theoretical studies, the general regularities have been revealed and the equations have been proposed for determining the equilibrium conditions of a deformable material layer and changes in pressure in the channel, taking into account the effect of the operating device and fiber properties. Analytical dependences and changes in the axial pressure along the channel are obtained reflecting the regularities of the fibrous material movement.
