After more than 15 years of grinding operations,
the first repair on the UHPC wear protection lining
are now necessary.
More than 15 years ago, the classifier housing and
the fine material discharge of the vertical roller
grinding system were lined with a UHPC wear
protection lining. The grinding system grinds a
special titanium ore for prigment production.
Originally, very little wear was expected and no
wear protection system was planned. However,
the regrind was extremely wear-resistant and after
a very short time after the vertical roller grinding 
system was put into operation, the sheet metal
construction showed considerable wear.
For fluidic reasons, only a layer thickness of 15 mm
for wear protection could be permitted. The
UHPC wear protection work was started quickly
and was completed within a few days. The
grinding plant was put back into operation after
six days of inactivity.
