Test items: For the determination of the degree of deduction of pulp, etc. DRK-PFI11 refiner (also known as demolition machine or vertical beater) is used in pulping and papermaking experiments for the determination of the deduction degree of pulp, the determination of pulp sample moisture, the determination of pulp concentration, and the The measurement of dissociation and freeness provides a standard quantitative sample. DRK-PFI refiner complies with ISO5264/2-1979 "Pulp Laboratory Refining-Part 2: PFI Grinding Method" and the experimental standards specified in ISO5264/2 and TAPPIT248. Instrument principle: The metered pulp with a specified concentration is placed between the knife roll and the smooth beating cylinder, and the knife roll and the beating cylinder rotate at different circumferential speeds. It acts on the pulp to achieve the purpose of beating. Features: Adjustable gap between flying knife and slurry tank wall; three sets of standard beating pressure quantitative combination; manual cutter head working up and down, safe operation and convenient cleaning; automatic control of revolution or time, high-brightness digital display rigid head, long time Use, the clearance gap is accurate. Cast base, stable operation and no noise. Instrument parameters: 1. Pulp tank: inner diameter: medium 250mm 53mm 2. Flying knife rotor: outer diameter: Φ200mm, height 50mm, knife thickness 5mm 3.
