Disk Mill

PULVERISETTE 13

premium line

Pressure and shearing action

In the Disk 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.

Easy operation – fast and efficient
The grinding chamber is locked at the push of a button and the grinding gap and grinding time are set precisely and to the second using the plus/minus keys on the digital display. Fill the sample into the easily closable funnel and start grinding. The last setting is saved and can accessed directly for the next grinding.

Especially precise motor-driven adjustment of the distance between the grinding disks without crank
The grinding gap can be conveniently adjusted with accuracy of 50 μm by means of the plus/minus buttons on the digital display. For reproducible results that are absolutely reliable.

Especially convenient motor-driven zero-point adjustment
For regularly compensating wear on the grinding disks and for easy precise re-adjustment after replacement.

Fast, residue-free cleaning
The completely accessible grinding chamber, the Clean Design with smooth grinding chamber inner surfaces and additional labyrinth sealing of the grinding chamber and the removable funnel - saves time and provides effective contamination protection for your samples.

Longer service life for grinding disks
With the control display, it is easy to prolong the service life of the grinding disks: simply change the rotational direction (clockwise/anti-clockwise) of the grinding disks to optimally compensate the abrasion behaviour.

Especially easy change of the grinding disks
In the PULVERISETTE 13 premium line, both the fixed and the movable grinding disks are easily accessible for fast, simple replacement. For the disk change, the disk is simply driven forward by the motor, allowing the retaining screws to be easily loosened.

Configure your Disk Mill PULVERISETTE 13 premium line exactly to your specific application

For every FRITSCH Disk Mill PULVERISETTE 13 premium line, you need at least one fixed and one movable grinding disk. These are available in 4 different materials. Normally, two grinding disks of the same material are selected which must always be harder than the sample to be ground.

Metal-free grinding

Ideal for medical and dental engineering: On request, we can equip your PULVERISETTE 13 premium line with a complete polymer interior coating together with grinding disks made of zirconium oxide – the perfect pre-requisite for grinding without any contact of the sample with metal.
