FOR CLEANING:
- waste paper pulp,
- brokes,
- unbleached or bleached half-stuff.
OPERATING PRINCIPLE AND ADVANTAGES:
- This relates to a:
- centrifugal sorter,
- non-pressurized,
- with closed rotor,
- with a holed basket.
Resulting in the following:
CENTRIFUGAL:
- There is a certain squeezing of the stock against the screen.
- The rejects are hence locally thickened and remain in the center, while the good diluted stock manages to cross the basket easyer to be drained in its periphery.
NON PRESSURIZED:
- The rejects are not pushed through the basket, hence a natural selectivity.
- Furthermore we save the energy of a pump.
WITH CLOSED ROTOR:
- To avoid nets especially with waste paper pulps.
BASKET WITH HOLES:
- Given the retational speed of the stock in the machine (about 1.3 m/sec.), produced by the rotor's movement, each hole in the basket is seen by the stock according to its horizontal projection i.e. more or less like a flattened ellipse (according to retational speed, consistency, nature and length of the fibres, etc.).
- The machine allows to collect:
- the good pulp on the outside of the basket.
- the rejects in the centre of the appa-ratus. These are then evacuated after being deluted by white water.
