Attritioning Cells

Attrition machines play an important role in wetmechanical processing techniques.
Under the influence of high shear and friction forces created by special agitators,
surface contamination is removed and agglomerates are disintegrated, due to the
high solid content and intense friction between the particles.

The slurry is fed into the first chamber and discharged from the last chamber. The
agitators guarantee safe transportation of the highly concentrated slurry through the
chambers. The design of each chamber and the arrangement of the agitators rule out
dead zones and short circuiting. This also ensures that the slurry is transferred through
each agitator zone.
