Influence of storage duration and density of raw cotton on the mechanics of the interaction process between feeding rollers in the cleaners of large impurities

Construction of a theoretical method for estimating the calculation of power used by feed rollers in the cleaners of raw cotton from fine debris

“…Papers [10,11] examined the influence of elastic characteristics of raw cotton on qualitative indicators for raw cotton. This work is continuation of the research into constructing a model of the process of contact interaction between blades and raw cotton; it describes the process both quantitatively, based on magnitudes for spreading efforts, and qualitatively.…”

“…The above-mentioned studies [10,11] calculated the energy consumed by feed rollers based on the condition for deforming a layer of raw cotton by rollers of round shape. At the same time, such a model does not take into consideration the power consumed for the displacement of a layer along the axis.…”

“…In the presence of elastic and plastic deformations, only that portion of energy would be returned to the roller that was spent on the elastic deformation component. It is possible to consider this phenomenon, reproduced in experiments [10], by a proportional decrease in the layer thickness at the output from a feed pair, or by reducing a medium rigidity coefficient under conditions of its unloading. Work on the axial displacement of the flow in ( 22) is naturally positive throughout the entire range of change in j i from 0 to π.…”
