Maintenance
9.1. General Maintenance
The metal separator is a sensitive measuring instrument. Erection and operation are
described in this manual. Usually, the metal separator works safely and reliably
without requiring further adjustments after commissioning. Necessary replacements
of parts of the metal separator or adjustments are decisively depending on the use
conditions.
In any case, the laminated-paper tube and the sorting gate should be regularly
checked for wearing. In case of handling glass fibre-reinforced materials or heavily
abrasive materials, the maintenance intervals should be short. Appropriate
maintenance intervals can be fixed up better in the course of operation. In the
beginning, daily or weekly inspections are required.
Take care of this notes !
The brown laminated paper tube gets thin due to heavy abrasion. Before breakage
due to abrasion, the paper must be renewed. It protects the highly sensitive ring coil
body against damage. If this advice is not observed, permanent damage may occur
to the ring detector, and complete replacement will be required.
Change of the bulk material may required readjustment of the sensitivity. That
happens, for example, on changing from non-dyed material to blackened, soot-
enriched material if increased rejects not caused by metallic contamination occurs.
