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.
- Feed size 20 mm
- Max. throughput 150 kg/h with extra powerful motor
- Rotating speed grinding disk 440 U/min
- Fine grinding down to 0.05 mm
- Motor-driven grinding gap adjustment in 0.05 mm steps
- Especially safe due to automatic safety locks for locking grinding chamber and drawer
- Easy cleaning and optimal material feeding due to large removable plastic funnel
- Clean Design: smooth grinding chamber inner surfaces and labyrinth sealing of grinding chamber ensure a fast cleaning an protection against contamination of the sample
- Dust-free grinding due to connection of dust exhaust system and special sealing of drawer
- Automatic safety locks for clamping the lock and grinding chamber drawer automatically
- Precise motor-driven adjustment of distance between grinding disks of up to 50 µm accuracy
- Motor-driven zero point adjustment for compensating wear on grinding disks and precise re-adjustment after replacement
- Longer service life of grinding disks via the control display
- Easy change of the grinding disks
- Combinable with the Jaw Crusher PULVERISETTE 1 premium line
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.
The premium combination for integrated pre- and fine-grinding
For especially fast continuous premium pre- and fine-grinding of large quantities of coarse material, the combination of the Disk Mill PULVERISETTE 13 premium line and the Jaw Crusher PULVERISETTE 1 premium line is the ideal solution. Together, they form an efficient, heavy-duty, high-performance grinding instrument with integrated Riffle Sample Splitter. This gives you the full range of opportunities for optimal sample preparation with a feed size of up to 95 mm and final fineness of down to 0.05mm – all in a single step.

*The three-phase AC version„/3~“ is definitely preferable over a single-phase version „/1~“, since you obtain with the three-phase AC version more power, better effectiveness and a greater energy efficiency.
Please note: the three-phase AC version „/3~“ must always be operated on a three-phase supply network.
