Bauer sieve (Bauer fiber sieve) is an instrument and equipment used in pulp and paper laboratories to measure the weight-average fiber length of pulp fibers by sieving. It is used to measure the proportion of fibers of different lengths in the pulp, and to grasp the distribution of fibers of various lengths in the pulp. This machine conforms to the sieving test method stipulated in GB/T 2678.1-1993, and also conforms to the sieving method test stipulated in TAPPI T233cm-95, and meets the Nordic SCAN M6 (10g sample, water flow 15min, flow rate 10L/min) experimental method. .
Principle: Pulp suspension is injected into the sieve, and each sieving container is equipped with a screen, and the container is stepped. When the pulp suspension flows from one container to another, different fiber lengths are retained on different screens. The pulp, the fiber length of the retained pulp is consistent with the mesh size of the sieve plate. After a certain time of sieving at a certain water flow rate. Collect the fiber on each sieve plate, dry it, and after constant weight, report the result according to the mass percentage of the input sample according to the amount of fiber retained on each mesh.
