Pressure calculation in a roller pair

As a result of studies on force interaction in a roller pair, a calculation formula was obtained for the specific pressure in a roller pair, for the case when the material being processed is elastically viscous and the rollers are drive. Analysis of the calculation formula showed that the specific pressure in the roller pair depends on the geometric parameters of the material being processed and the roller coating, the viscosity coefficient of the material being processed, and the strain rates of contacting bodies. A formula was obtained to determine the value of the strain coefficient of the processed material under recovery, providing conditions for conjugating strains in the compression and recovery zones.
