Fiber length is among the most crucial properties of paper pulp. When sets of different fiber lengths were compared, those with long lengths were able to create a more powerful network than the short ones. This is because a long fibre has more fibre joints. The classification and identification of fibre lengths are therefore important in the papermaking process. And to do this, manufacturers make use of UEC’s high-quality fibre classifiers.

In the following section, we will throw light on the top two fiber classifiers manufactured and supplied by UEC.

2 High-Quality Models of Fibre Classifiers by UEC

1. Bauer McNett Fiber Classifier - Stainless Steel Screen Model (With 3, 4 & 5 Tanks)

  • The Bauer McNett fiber classifier is a high-quality pulp testing equipment that evaluates the fibre length distribution of pulp using the classification method.
  • This automatic instrument is operated using a control panel. To perform the test, the operator sets the test conduct time using a sequence control timer, which automatically stops after the test set time is over.
  • The model consists of pulp tanks. In each tank, there is a cylindrical agitator with short paddles. This agitator rotates through a motor and makes the suspension to horizontally flow across the screen and disperse around the tank.
  • Besides the agitator, the model also contains a mesh screen frame with spring-loaded clamps, a pulp collection/suction cup, and a drain lever. Users can choose interchangeable mesh screens, as per TAPPI standard series or Tyler series. The wire mesh sizes in the TAPPI series include 16, 30, 50, 100, and 200. The mesh sizes in the Tyler series include 14, 28, 48, 100, and 200.
  • The first pulp tank is attached to a water inlet valve, a water flow meter regulates it. In the case of a high or low flow rate, the alarm rings. The last pulp tank connects with a water overflow outlet pipe.
  • The suction cups connect with a suction vacuum pump, which is used to drain the excess water, the pulp contains. When the suction begins, the pulp remains can be washed on the mesh frame and tanks using a hand shower, which is already connected to the base frame.
  • The entire unit (including all 4 pulp tanks) comes in size 171 x 81 x 160 centimetres.
  • The instrument follows these National/International standards: SCAN M6, TAPPI  T 233, and PAPTAC C5V.
  • The Bauer McNett fiber classifier is capable of testing Recycled fibre, agro fibre, and wood fibre.

 2. Bauer McNett Fiber Classifier - Frame Model (With 3, 4 & 5 Tanks) 

  • The frame model is another one on the list of high-quality fibre classifiers. This too uses the classification method to investigate the distribution of fiber length in the pulp.
  • In each pulp tank, there is a cylindrical agitator with small paddles. This agitator rotates through a motor and makes the suspension horizontally flow across the screen and disperse around the tank. 
  • The unit also contains a mesh screen frame with spring-loaded clamps, a pulp collection/suction cup, and a drain lever. Users can choose interchangeable mesh screens, as per TAPPI standard series or Tyler series. The wire mesh sizes in the TAPPI series include 16, 30, 50, 100, and 200. The mesh sizes in the Tyler series include 14, 28, 48, 100, and 200.
  • The first pulp tank connects with a water-filling chamber, while the last pulp tank with a pipe that lets the water out.
  • There is also a control panel that operates the functions of the instrument. Both the control panel and pulp tanks are combined in the Cascade mode. They are placed on the top of an S.S. frame with a base tray that drains the water. 
  • Users can opt for fibre classifiers with 3, 4, and 5 pulp tanks, as per their requirements.
  • The entire unit (with standard 4 pulp tanks) comes in size 151 x 60 x 164 centimetres.
  • This instrument follows these National/International standards: SCAN M6, TAPPI  T 233, and PAPTAC C5V.
  • The frame model is capable of testing Recycled fibre, agro fibre, and wood fibre.
