PFI Type Mill – Laboratory Pulp Beater
Automated laboratory pulp beater. Very repeatable beating results. Automatic loading and unloading of the beater roll. Auto wash cycle and soft start. Complies with ISO 5264/2. Capable of beating 5 - 40g of pulp at 5 - 50% consistency.
Automatic Laboratory Beater for the beating of pulps. Subjects pulp to a user specified or standardised and repeatable beating schedule prior to the production of hand sheets and freeness tests
The cylindrical chamber turns at 720 +/-20 rpm and the beater roll with 33 bars at 1440 +/- 30 rpm both in the same direction. The beater roll is pressed against the chamber wall with 3.33 N/mm of bar length. The pulp is beaten under the pressure between the wall and the bars. The beating time is selectable between 2 an 10 minutes according to the kind of pulp.
Standards
Complies with ISO 5264/2, DIN-EN 25264-2, SCAN C 24, TAPPI T248, PAPTAC
Method of Operation
A weighed and disintegrated pulp sample is put into the chamber. By hand the pulp sample is pressed evenly to the outside wall of the container. The swivelling beating head is placed over the chamber and the beating procedure starts when the head is lower into the chamber.
By moving the hand lever, the beating head presses against the chamber wall. There is no direct contact between the metal parts. The mill beats to the preset number of revolutions. After reaching the selected number of revolutions the machine stops and the beating procedure ends. The head is moved again into the lateral position, the pulp is taken out of the mill and the SR value and/or the CSF value is determined.
