Estimating the area and number of bar crossings between refiner plates

Abstract
A novel methodology for estimating the area and perimeter of intersection between two or more intersecting surfaces, without having to determine or order the points of intersection, is presented. No restriction is placed on complexity of the intersecting geometry except that it must represent a closed region. This method is well-suited for cases in which the area and perimeter of intersection are complicated, are not strongly peaked in a very small region, and when relatively low accuracy is tolerable. In this study, we examine the time-dependent evolution of the area and number of bar crossings for 320 different low consistency refiner plate configurations with similar geometrical patterns for stator plate and rotor plate using this methodology. Empirical correlations are presented to relate the plate parameters to bar intersection area. Finally, we interpret our findings in terms of the industrially accepted parameters used to characterize the action of refiner plates.
