Target group: operating company, operator
Designation of the machine type: RS 300
The RS 300 vibratory disc mill is used for the fast, loss-free and reproducible pulverisation of
medium-hard, hard, brittle and fibrous materials to analytical fineness. Thanks to the innovative
Cardan drive (3-dimensional grinding movement), the mill runs quietly and safely, even with
heavy grinding sets.
The vibratory disc mill is deployed successfully in almost all areas of industry and research.
This particularly applies to those with requirements regarding purity, speed, fineness and
reproducibility.
Since the RS 300 achieves very high levels of final fineness in the shortest time, it is especially
suited to preparing samples for spectral analysis.
Due to its strong design, the RS 300 has proven itself in the building materials sector (cement),
in geology, mineralogy, metallurgy and in power stations.
Soil, concrete, electronic components, ores, glass, ceramic, coal, coke, corundum, metal
oxides, minerals, parts of plants, slag, silicates, cement, cement clinker and many other
substances can be ground easily, quickly and without loss.

Technical Data

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
