The PL10-00 Fiber Classifier is the equipment used for measuring the weight-average fiber length of pulp fiber.

1.Introduction:

Fiber Classifier (Bauer Fiber Classifier) is the equipment used for measuring the weight-average fiber length of pulp fiber according to screening method by pulp and paper-making laboratory. This machine conforms to the screening methods stated by GB/T 2678.1-1993, TAPPI T233cm-95 and. It can also be used to measure the ratio of different fibers in the pulp.

2.Main Parameters

1)  Agitator speed: 650 n/m

2) Water flow adjustable range: (2-18 L/min)

3) Sieving time: 20min ± 10s, adjustable automatic control time.

4) Sieving plate standard: 10 mesh, 14 mesh, 28 mesh, 48 mesh, 40 mesh, 50 mesh, 60 mesh,80 mesh, 100 mesh, 120 mesh, 150 mesh and 200 mesh are optional.

5) Power voltage: 380V.

6)Power: 60W × 4.

7)Dimension: 1780mm × 550mm × 1680mm.

3.Sieving Principle

The PL10-00 Fiber Classifier consists of four flat cylinders, a depth of approximate 355 mm, width 127 mm, and length 320 mm. Both sides of the flat cylinder are half cylindrical shape and each one is equipped with a screen mesh, about 335 cm2.

Four cylinders are installed on one frame body, which are lower and lower to form a step-type tandem arrangement. On the half cylindrical side of each cylinder is equipped with a vertical cylindrical agitator (with vertical ridges outside of the cylinder) with short leaves, rpm. 650 n/min, driven respectively by four vertical electric motors. In each cylinder sizing material rotates around the cylinder in the horizontal direction so as to flows to the central guide board and goes through the narrow channel and the screen meshes. The outlet of each screen mesh has an overflow weir plate and a short curved plate, which leads the overflow to the cylinder with a smaller screen mesh and to the trench of the last cylinder. Loosen the clamp bolt of the cylinder board, and take the screen mesh frame out from each cylinder, clean it or change the screen number (mesh size).

4.Structural Features

The PL10-00 Fiber Classifier includes reducing motor, agitator, water tank, stander, unit switch, timer and flow meter and so on.

Water tank is the main device of this machine, the agitator is used to make fibers spread in water sufficiently, do directional movement and parallelly go through screen mesh for separation. Sieving plate prevent water and fibers from rush at screen mesh vertically, and screen mesh is mainly for fiber grading.
