Determination of roll power required for rolling of plastic and rubber mixtures

Calculations of the power required for the rolling of a material, whose behavior under load is described by a power law, is analyzed, proceeding from the dissipation power released in the material being reworked as a result of its deformation in the inter-roll gap, and also from the torque required to turn the rolls. It is demonstrated that both approaches are acceptable for a common roll drive, while it is expedient to use a procedure based on calculation of the torque required to turn the rolls when individual drives are employed for the latter.
