An agitated pulp suspension is fractionated by means of a screening process employing vertical screens with increasing wire sieve cloth numbers. The screens are mounted in tanks arranged in cascade.
The mass of the fibers retained by each screen and of those passing all the screens is determined and expressed as a percentage of the oven dry mass of the original sample. (SCAN M-6). For investigating the fiber length distribution in pulp. Each unit is provided with an electric motor for driving the rotor and is fully self contained. All units easily combined in cascade mode due to modular construction. Interchangeable screens available.

The primary unit has an inlet funnel with an overflow and the nozzle for a constant water flow rate. Fractionating unit is completely self-contained having its own electric motor for the rotor and is made of non-corrosive material.

Fiber collection box with rapid locking device, support wire and suction connection.

The screen frames are clamped spring loaded self clamping system.
