standard laboratory PFI mill PFI beater

PL11

 

The PFI mill is a beater featuring a high reproducibility, used for studying the relationship between beating degree of pulp and physical properties. This machine is basically an experimental beater widely used in the preparation stage of paper making. Beating mechanism: a constant load is given to the pulp circulating in between stainless steel roll and cylindrical mill house, which are rotating with a constant difference in circumferential velocity, applying mechanical effects such as shear and compression, thereby performing beating by frictional forces between fibers.

The number of rotations is read on the counter. The beating degree is evaluated by the freeness tester.

PL11 PFI Beater(PFI Mill)  it is uses in the pulping papermaking experiment, for the paper pulp buckle Xie Du determination, the paper pulp test specimen moisture content's determination, the paper pulp density's determination, the wet degree of dissociation's determination, the degree of ionization determination provides the standard specimen, the PL11 refiner conforms to ISO 5264/2-1979 "the paper pulp laboratory beating - - second part: PFI bothers the experiment standard which" as well as ISO5264/2, TAPPIT248 stipulated.

Principle: Has the normal concentration paper pulp after the measurement to put between the knife roll and the smooth beating cylinder, knife roll and beating cylinder by different circumferential velociy revolving. By this function in the paper pulp, achieves the beating the goal.

Characteristic:

Adjustable internode fly cutter and stuff chest intermural crack; Three group of beating pressure combination; The manual cutter head high and low work, the operational safety, the clean is convenient; Rotation or time automatic control control, high luminance numerical code demonstration; The rigid nose, the long time use, knocks on the solution gap to be accurate. The casting foundation, the revolution is steady, does not have the noise.
