Description

A pulp sample of 30 g (od) at 10% consistency is beaten between a roll with 33 bars and the smooth inside of the beater housing at a certain speed, with a certain pressure for a certain number of revolutions. Typical time for beating is between two and ten minutes.

Test description

A prepared pulp sample is distributed on the inside wall of the housing. After the roll has been swing in, both start buttons left and right of the mill are pressed. Die roll is lowered down into the housing and the cover is pneumatically closed. The beating elements are started automatically and the roll pressed against the sample with the selected force. At the end of the pre-set number of revolutions, the PFI mill is stopped automatically, which is then opened by pushing the two buttons left and right.
