Application

Elaboration of ceramic pigments. Product: alcohol + chemicals + pigments. The mix circulates through a chamber of alumina microspheres (0.2/0.5 mm) to achieve an intense milling, obtaining a final product (ink) of uniform texture.

Pmax: 4 bar
T: unknown

Diagnosis

The microspheres have hit the internal parts of the mill, causing wear.
