High final fineness for large quantities
The especially heavy and solid FRITSCH Disk Mill PULVERISETTE 13 classic line is the ideal instrument for fine grinding of up to 150 kg per hour of hard-brittle and medium-hard solids – even in continuous operation. The maximum feed size per piece is approximately 20 mm edge length, the final fineness is freely adjustable between 12 mm and 0.1 mm.
| Working principle | shearing |
| Optimal for material type | very hard, hard-abrasive, hard-brittle, medium-hard samples and for metal-free grinding |
| Grinding tools | fixed and movable grinding disk |
| Materials of the grinding tools | hardened steel cast, manganese steel, hardmetal tungsten carbide, zirconium oxide |
| Max. feed size (depending on the material) | 20 mm |
| Min. sample quantity | 20 – 30 ml |
| Max. throughput (depends on material) | 150 kg/h |
| Final fineness | 0.1 – 12 mm |
| Feeding | batchwise/ continuous |
| Rotating speed | grinding disk 440 rpm |
| Bearings | needle and double row angular contact ball bearings |
| Electrical Details* | 400 V/3~, 50 Hz, 1790 watt |
| Instrument also available in the following voltage (other voltages on request) | 200 V/3~, 60 Hz, 2100 watt order no. 13.1020.00 |
| Emission sound pressure level at the workplace according to DIN EN ISO 3746 (depending on the material to be ground) | approx. LpAd = 81 dB |
| Weight | 140 kg |
| Dimensions (W x D x H) | bench top instrument 44 x 87 x 40 cm |
*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.
HIGH FINAL FINENESS IN MINIMUM TIME
Below are examples listed – always in reference to 1 kg feed quantity and 20 mm particle size and arranged by material types from hard to medium-hard.

PLEASE NOTE
| The indicated results are to be considered as an orientation guide, since the chemical and physical properties (e.g. residual moisture, morphology, etc.) can vary even with the same material to be ground. |
Pressure and shearing action
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 a pre-set grinding gap into the collection drawer. The desired final fineness can be defined from the outside by changing the gap width.
- Precise gap adjustment with an accuracy of 0.1 mm
- Fast, easy cleaning
- Simple operation
- Fast grinding disk change
- Precision setting of the final fineness even during grinding
- High service life due to generously dimensioned bearings
- Especially safe due to central tension lock of the grinding chamber
- Easy gap width check from the outside
- Combinable with the Jaw Crusher PULVERISETTE 1 classic line
Configure your Disk Mill PULVERISETTE 13 classic line exactly to your specific application
For every FRITSCH Disk Mill PULVERISETTE 13 classic line, you need at least one fixed and one movable grinding disk, which are available in various materials. Normally, two grinding disks of the same material are selected, which must always be harder than the sample to be ground. Grinding disks of zirconium oxide are only suitable for grinding ceramic materials, minerals, etc. and never for hard-tough samples, such as metals.
Metal-free grinding
For completely metal-free grinding of hard-brittle and medium-hard solid samples, for example for dental ceramics, we can equip your FRITSCH Disk Mill PULVERISETTE 13 classic line with a thorough polymer interior coating – together with grinding disks made of zirconium oxide – an absolutely reliable protection against iron contamination.
