Retsch RS 300 - Grinding Jar Nominal Volume; Feed Size

Technical Data
19
Benefits
– Reproducible grinding results due to "Cardan drive" (grinding jar has 3-dimensional
movement during grinding)
– Extremely short grinding time
– No sample loss thanks to optimal O-ring seal
– Large selection of materials for neutral-to-analysis grinding
– Closed, noise inhibiting grinding chamber
– Pneumatic clamping of grinding jars (automatic)

Wear or damage to the grinding set
Insufficient fill quantity
− Increased wear or damage to the grinding set is possible if the grinding
set is operated with insufficient fill quantity.
− The grinding set must be filled to at least 1/3 of the nominal
volume.
4.3 Feed size
The maximum feed size depends on the grinding jar volume and the hardness of the sample
material .
Grinding set 100 ml = max. particle size < 10 mm
Grinding set 800 ml = max. particle size < 15 mm
Grinding set 1000 ml = max. particle size < 15 mm
Grinding set 2000 ml = max. particle size < 20 mm
