PFI

PFI-Type Laboratory Refiner

PFI-type laboratory refiner, designed to refine pulp under standardised conditions and even for the defiberisation of semi-cooked fibres. The refining mill and cylindrical container are made of stainless steel, capable of refining between 5 and 40g of pulp at a concentration of 5 to 50% (max. 450ml of suspension).

Key Features

• Excellent repeatability, for quality control and research.
• Safety elements for user and equipment protection.
• Raising and lowering of the refining cylinder by electric automatic manoeuvre.
• Easy to operate, with pre-selection of refining mill revolutions and automated process.
• Adjustable refining pressure: 1.0–5.5 N/mm of cutting blade length.
• Calculation of times, absorbed power (W, continuous measurement) and energy consumed (kWh) during refining.
• Modern, easy-to-clean design with all measurement and actuation instruments integrated in a raised front control panel.

Applications

Widely used for laboratory beating of chemical pulps under standardised conditions, simulating commercial refining practices to characterise pulp performance ahead of paper conversion. Meets ISO 5264/2 and TAPPI T248.
