Overview
The Triple Disc Refiner is a high-performance fibre refining system engineered for controlled fibrillation and development of pulp fibres used in paper and board manufacturing. Designed for laboratory research as well as pilot-scale operations, the QGI Triple Disc Refiner provides precise refining action through a three-disc configuration that enhances fibre bonding strength, improves pulp freeness control, and ensures uniform fibre development. The equipment is widely used in pulp and paper laboratories for refining chemical, mechanical, and recycled pulp while maintaining consistent process conditions required for reliable testing and product development.
