Overview
The Fibre Fractionator (Somerville Type) is a precision laboratory instrument designed for determining the content of shives, contaminants, and coarse fibre fractions in pulp suspensions. It is widely used in pulp and paper testing laboratories to separate oversized particles, stickies, plastics, and other impurities from fibre suspensions for accurate analysis and quality control. The system operates on controlled hydraulic screening combined with diaphragm-driven oscillation to ensure reliable fibre classification and impurity measurement in accordance with international pulp testing standards such as TAPPI T275, TAPPI UM242, and PAPTAC C.11P.
