THE PRODUCT IN FOCUS

Model overview

Thanks to the robust universal drive shaft, which sets the grinding jar into a 3D motion, the RS 300 accepts grinding set weights of up to 30 kg. The closed grinding system guarantees complete processing of the sample.

Grinding sets are available in a variety of sizes and materials, allowing for easy adaptation to application requirements.

PERFORMANCE & OPERATION

Features. Operation. Handling.

ERGONOMIC HANDLING AND EASY OPERATION

Operation and handling of the RS 300 and its grinding sets is convenient and ergonomic. The AutoLifter is an optional accessory which greatly facilitates ergonomic lowering and lifting of the high-capacity grinding sets. It is simply placed around the grinding set and activated by pushing a button.

The pneumatic clamping device allows for convenient and safe fastening of the jar. The mill only starts if the pneumatic pressure is correct and the device lifts automatically when the grinding process stops.

The grinding parameters are entered using a keypad. While the programmable interval function helps to improve grinding results, the autoreverse function reduces caking effects inside the grinding jar.

FUNCTIONAL PRINCIPLE

The vibratory disc mill comminutes by impact and friction. The grinding set is firmly attached to the vibration plate with a pneumatic quick clamping device. The plate with the grinding set is subjected to 3-D vibrations.

The sample is crushed by extreme pressure, impact and friction generated by centrifugal forces acting on the grinding rings in the dish.The vibrations are produced by a frequency controlled 2.2 kW 3-phase motor.

APPLICATIONS & METHODS

Build the process around the sample.

FAST AND REPRODUCIBLE

Very short grinding times, typically in the range of 60 to 180 seconds to achieve a fineness around 100 μm
Ergonomic design and carry handles ensure easy handling of the grinding set
Quick-action clamping system enables convenient and safe tightening of the grinding set
Automatic speed reduction for agate and tungsten carbide sets
Powerful Stabilized-Plane-Drive improves reproducibility
Variable speed from 700 to 1500 rpm

REPRODUCIBLE AND SAFE

Reproducible results and homogeneous samples thanks to universal drive shaft
(3D vibration of grinding sets)
Auto-reverse function (left/right rotation)
Programmable interval function (start/ stop automatic)
Grinding jar volumes from 100 ml up to 2,000 ml
Pneumatic grinding-jar clamping (with air-pressure) for convenient and safe handling
Additional safety feature: Mill only starts when the pneumatic pressure is correct
Optional AutoLifter for ergonomic lifting of heavy grinding sets

HIGH-QUALITY GRINDING SETS

Thanks to a variety of sizes and materials of the grinding sets, the RS 300 is suitable for a wide range of applications. The mill accommodates batch sizes from 35 ml to 2000 ml and material feed sizes up to 20 mm.

A grinding set for the vibratory disc mill consists of a grinding jar with cover and a grinding disc. The 400 ml grinding set also contains a grinding ring, the 300 ml grinding sets has two additional grinding rings.

The grinding sets are characterized by the following features:

Safe, non-slip attachment with anti-twist lock on cover and base
Gap between dish and cover edge for easy opening
Optimum sealing with O-ring (ideal for wet grinding)
Clear grinding set identification (article number, material and volume)
The disc of the 800 ml, 1000 ml and 2000 ml grinding sets has an opening which supports perfect mixing of large sample quantities
