*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.

WORKING PRINCIPLE

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.

FEATURES

Feed size up to 20 mm
max. throughput150 kg/h
Final fineness 0.1 -12 mm
Rotational speed grinding disk 440 rpm
Precise gap adjustment with an accuracy of 0.1 mm
Especially safe due to central tension lock of the grinding chamber
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
Easy gap width check from the outside
Combinable with the Jaw Crusher PULVERISETTE 1 classic line

EQUIPMENT / ACCESSORIES

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.

HIGH FINAL FINENESS IN THE SHORTEST TIME

Especially time saving:
The grinding chamber can be completely opened which makes cleaning especially simple and the grinding disks are very easily accessible for changing.

Especially accurate
The precision sliding table of the FRITSCH Disk Mill PULVERISETTE 13 classic line for precise gap adjustment with an accuracy of 0.1 mm – for rapid, precise operation and exactly reproducible grinding results.

Safe and easy to clean
The completely accessible grinding chamber makes cleaning particularly easy and the grinding disks particularly accessible for changing. The grinding chamber is locked by a central tension lock with a single motion. The optional dust exhaust system for connecting an extraction device makes it particularly easy to automatically remove the fine dust produced during grinding and is also ideal for cleaning the grinding parts.

Practical grinding gap adjustment via precision sliding table
The grinding gap is set via the precision sliding table with 0.1 mm accuracy using a crank – for fast, accurate work and precisely reproducible grinding results. The gap width check can be conducted from the outside (e.g. with thickness gauge).

Longer service life of the grinding discs by reversing the direction of rotation
The service life of the grinding discs can be extended simply by reversing the direction of rotation of the maintenance-free three-phase geared motor.

Especially solid
The thick-walled housing of the FRITSCH PULVERISETTE 13 classic line consists of recyclable grey cast iron.
