Experimental study of some factors affecting pulp screen capacity

Abstract

The effect of screen cylinder geometry, pulp type, and rotor speed on screen capacity was investigated. Five screen cylinders with different slot geometries were tested using different ratios of softwood/hardwood kraft pulp mixtures and different reject ratios. The relationship between the rotor speed and screen slot velocity at the verge of plugging, taken here as a measure of "capacity", was found to be remarkably linear. Feed consistency and fibre length were found to have significant influences on capacity
