Disk mill for sample fine grinding down to 50 µm

The laboratory equipment producer Fritsch from Idar-Oberstein/Germany has improved its premium disk mill. The instrument for efficient fine grinding of hard-brittle to medium-hard solids offers more safety, as it has automatic locking of the collecting vessel and grinding chamber. Due to the convenient motor-driven grinding gap adjustment with digital gap display it is even easier to operate. A well-designed display shows all of the parameters of the new instrument that is ideal for medium particle sizes in the areas of mining and metallurgy, ceramics industry, rocks and soils, glass industry, soil research.

In the mill, the material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth. The ground material automatically falls down through the pre-set grinding gap into the collection drawer. The desired final fineness can be defined reproducibly by simply adjusting the digital setting of the gap width.

The technical features are:

Easy, motor-driven grinding gap adjustment with digital gap display

Automatic locking of the grinding chamber

Easy operation and cleaning with Clean Design

High throughput of up to 150 kg/h with extra powerful motor

Fine grinding down to 0.05 mm

Large, removable funnel – for especially easy cleaning and optimal material feeding

Dust-free grinding due to the connection of a dust exhaust system – directly controlled via the instrument

As with all of the instruments in the Fritsch premium line, the engineers have put a great deal of thought into how to make daily laboratory work even easier and time-saving: The user can simply press the button to lock the grinding chamber, use the plus/minus buttons on the digital display to set the grinding gap with accuracy of 50 μm as well as the grinding time with accuracy to the second, fill in the sample into the easy-to-close funnel and start the grinding process. The most recent setting is saved and can be accessed directly for the next grinding, for reproducible results that are absolutely reliable.

With the control display, it is easy to prolong the service life of the grinding disks. By simply changing the rotational direction (clockwise/anti-clockwise) of the grinding disks the user can optimally compensate the abrasion behaviour.
