Pulp classifier (4-tank standard type) No.2590-I

This tester readily screens pulp fibers through screens into groups by fiber length. It consists of four screening tanks with wire cloth of different mesh sizes and an injection tank. As water and pulp are poured into the tanks together at a certain flow rate, fibers run along on the water flow to be screened into the four tanks serially placed on steps. Agitators are provided in order to prevent fibers from being deposited on the screens. The component elements are coupled together with a V-shaped belt, simplifying the mechanism and controlling noise.

The serial arrangement of the tanks achieves superior operability and allows the tester to be installed along the wall.
The drain valves of the respective screening tanks are eliminated and now rubber stops are employed, preventing fibers from depositing inside tubes. Alternatively, a model with ball bearings is also available.
With a ball bearing working in the agitator section, this tester runs with smooth rotations and low noise.
As the specimen injection tank is provided with a built-in top plate, check or washing the inside can be done easily.
To fix metal screens onto the tanks in place, a lever can be used for tightening, which leads to a significant improvement of workability (optional).
