Paper Abstract

Fines are defined as the part of mechanical pulp which has lost its fiber like state. It is considered as an important fraction of the raw material, because it improves paper web properties, e.g. tensile strength and opacity. Our machine vision based measuring system is one of the first approaches to measure the fines fraction properties directly. Since a sample is imaged in flow, it is possible to collect a large quantity of images easily. The sample is then characterized by the statistics of its particle geometry.
