The PFI refiner of FRANK-PTI in Germany is used in pulp and paper experiments, providing standard quantitative samples for the determination of pulp resolution and freeness. The 30g slurry with a concentration of 10% is evenly placed on the smooth grinding cylinder wall, the cutter roller and the grinding cylinder rotate at a certain speed, and the cutter roller applies pressure to the slurry at a pressure of 33bar, and the cutter roller and the grinding cylinder stop refining after reaching a certain number of revolutions, and the typical refining time is generally 2-10 minutes.
• High precision roll rotation speed
• The stainless steel body is durable and stable
• Anti-rust structure of the fuselage
• Two-handed operation of the button for high safety
• Rotating parts are not exposed, effectively preventing accidents
• Touch screen control, easy to operate
