Laboratory disc mill
for fast, loss-free and reproducible fine comminution and homogenization of samples
Sample preparation in a laboratory disc mill has been a tried and tested method for decades, especially in the fields of geology, mineralogy, metallurgy, the glass/ceramics industry, the construction materials industry, soil/plan analysis and power plants.
The laboratory disc mill enables fast, loss-free and reproducible fine comminution and homogenization of the samples.
The grinding barrels can hold sample batches of 10 – 1000 cm³ and grind and homogenize the sample material to final finenesses of up to < 40 μm*1) in a single step.
Sample preparation with a laboratory disc mill is thus the ideal prerequisite for subsequent analysis using X-ray spectrometers, regardless of whether pressed tablets or melt tablets are produced from the ground samples.
Our laboratory disc mills are also available in fully automatic versions, in which the grinding vessel remains in the machine and only sample feeding and removal are performed externally.
*1) The fineness achievable depends on the sample material, the grinding barrel, and the mill settings.
Automatic laboratory disc mill
With the automatic laboratory disc mill, the grinding barrel remains in the machine and does not have to be removed to take out the sample material. This eliminates the need for the operator to handle the grinding barrel, which makes the work much easier and more ergonomic.
Operating sequence of the automatic laboratory disc mill
- Filling the sample material into the feed chute of the machine
- Starting the machine
- Sample material falls into the grinding barrel and is comminuted and homogenized according to the preset time and rotational speed
- Emptying the grinding barrel into a sample cup
- Output of the ground sample material in the sample cup
- Flushing the grinding barrel with compressed air and/or flushing material
The TS 1000-A can be upgraded to a fully automatic sample grinding station via optional sample magazines. In this case, the operator only has to fill the magazine with samples to be ground and remove the ground samples from the magazine. Depending on the selected size of the magazines, the machine can be operated autonomously for longer periods of time.
Operational behaviour and mechanical characteristics
The grinding tools (stones/rings) in the grinding barrel are set into a rolling impact motion by means of a circular oscillation. This motion achieves very high forces, which rapidly result in fine comminution to
On the TS models the machine switches itself off automatically on expiry of the time preset on the keypad and the milling unit can be removed. This ensures a high degree of reproducibility in sample perparation.
The vibrating-disc mill is manufactured in two different versions, the T and the TS model. The TS version is a ready-to-connect machine, including control system and noise suppression in the sheet-steel housing, for installation in the laboratory. The T model is the low-price version without control system and noise-suppressed housing.
The laboratory disc mill is available in different designs:
- with manual or pneumatic closing device
- in sound-insulated housing (TS design) or also free-standing (T design)
- in fully automatic versions, where the grinding barrel remains in the machine and only sample loading and removal is performed from outside.
- integrated in an automatic milling and pressing system (AMP), which – in a
single device – combines all processes from pre-crushing dividing, fine grinding, and compression of the powder into a tablet.
