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.

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.
