Service Life; Replacing Grinding Disks - Animo OptiBean Service Book

OptiBean (XL)

1.4.3 Service life

The service life of the ceramic grinding disks is approximately 3x longer than steel grinding disks. The
service life depends on the type of coffee beans* and is approx. 3,000 kg of coffee beans. With an
average measure of 7.5 g/cup. that makes approx. 400,000 shots (XL=300,000 shots 9.5 g/cup)
When you reach these grind quantities, we advise you to replace the complete grinder. Not only the
grinding disks need to be replaced, but the bearings, carbon brushes and drive belt have also reached
their maximum service life. In case of a damaged grinding disk (due to stones or other foreign objects)
they can be ordered and replaced as a separate set.
* light to dark roast, dry or oily, caramelized
1.4.2 Run in period grinding discs
Tests have shown that new ceramic grinding discs have
a run in period of 10 kg of coffee beans (about 1350 cups
at 7.5 g / XL=1000 cup at 9.5 g.). We recommend to re-
adjust (¿ ner) the grinder after this period.
