The Bauer screening instrument (5-level screening) is an instrument and equipment used in pulp and paper laboratories to determine the weight average fiber length of pulp fibers using the screening method. Used to measure the proportion of fibers of different lengths in pulp and grasp the distribution of fibers of various lengths in the pulp.
The Bauer Fiber Siever is an instrument and equipment used in pulp and paper laboratories to determine the weight average fiber length of pulp fibers using the sieving method. Used to measure the proportion of fibers of different lengths in pulp and grasp the distribution of fibers of various lengths in the pulp. This machine complies with the screening test method specified in GB/T2678.1-1993, as well as the screening test method specified in TAPPIT233cm-95, and meets the experimental method of Nordic SCANM6 (10g sample, water flow for 15 minutes, flow rate of 10L/min).
Bauer screening instrument(5-level screening) principle:
Inject the pulp suspension into the sieve, and each sieve container is equipped with a sieve. The containers are stepped, and when the pulp suspension flows from one container to another, pulp of different fiber lengths is retained on different sieves. The fiber length of the retained pulp is consistent with the mesh size of the sieve plate. After sieving at a certain water flow rate for a certain period of time. Collect the fibers on each sieve plate, dry them, and after constant weight, report the results of the mass percentage of the input sample based on the amount of fibers remaining on each mesh.
Bauer screening instrument(5-level screening) Application areas: textile, papermaking, chemical fiber and other industries.
