<strong>SpeedWasher</strong><br />
Efficient and selective de-<strong>ashing</strong><br />
The ANDRITZ <strong>SpeedWasher</strong> is used for<br />
removal of inorganic material (filler and<br />
coating pigments) from a fiber suspension.<br />
The machine is a device with an endless wire,<br />
running at a speed of up to 1000 m/min.<br />
The de-<strong>ashing</strong> effect results from onesided<br />
dewatering of the fiber suspension<br />
between a forming roll and the wire.<br />
Pigments are enriched in the filtrate which<br />
is de-aerated and discharged by means of<br />
spin tubes. The thickened, de-ashed stock<br />
builds a fiber mat, is doctored off the rolls<br />
and transported out of the machine by a<br />
screw conveyor.<br />
Benefits<br />
• High de-<strong>ashing</strong> capability and discharge consistency due<br />
to strong thickening effect<br />
• Low energy demand<br />
• Cantilever design for fast and easy change of endless wire<br />
• Headboxes with cross-flow distributors and diffuser inserts<br />
for optimum pulp distribution and uniform dewatering<br />
• Efficient wire cleaning by high pressure needle jet nozzles<br />
• Oscillating doctors for gentle pulp take-off<br />
from forming rolls<br />
• Closed design with vapor hood and splash guards<br />
