Technical Specification

Device Description : The PFI Laboratory Mill consists of an inner toothed roll of 33 blades and a smooth beater housing . the roll rotates in the same direction at different peripheral speeds . A beating force of exactly 3.33 N/mm ensures that the pulp is beaten under standard conditions . A measured amount of pulp of specified consistency is beaten between a roll with bars and a smooth beater housing both rotating in the same direction but at different peripheral speeds.

Test Description : A weighed and disintegrated amount of pulp is put inside the housing . the operation must be done manually , placing the pulp along the housing wall . the roll is lowered and inserted into the housing . the security cover is also put out. After pushing the start button , the test starts . the housing will rotates with 710rpm and the roll @1455 +- 30rpm , both in the same direction . the roll exerts a constant pressure of 3.33 N/mm against the housing wall , where the pulp is located. This way due to the pressure applied between the housing g wall and roll blades the pulp is refined . the refining time varied from 2 to 10 minutes depending upon the type of pulp used . after having rotated the pre selected rotations , the roll and the housing stops and refining process ends. Finally the roll is situated in the center initial position and the refined pulp is extracted to measure the freeness of the pulp in degree SR or CSF.
