8.1 Grinding elements
NOTICE!
Cool grinding elements made of agate, sintered
corundum, zirconium oxide and silicon nitride slowly
and carefully.
Do not heat agate elements in a microwave under any
circumstances (heating is too fast).
They must never be exposed to thermal shocks as this
could cause irreparable damage to the parts
®
They
will burst apart like in an explosion.
n
Clean the grinding bowl and grinding balls each time after using
them: Clean them, e.g., under running water using a brush and a
commercially available cleaning agent.
n
Half fill the grinding bowl with grinding balls, sand and water, and
run with maximum speed for 2 to 3 minutes (correctly tensioned) in
the Planetary mono mill.
n
Cleaning with an ultrasonic cleaner is permitted.
n
For sterilisation in the heat cabinet, only heat the grinding elements
up to 100 °C.
