Disk Mill PULVERISETTE 13
for continuous size reduction within the medium particle size range
The maximum throughput of 150 kg/h depends on the gap setting and the hardness of the sample. The relatively large throughput enables it to be used in the pilot scale or in the small size production, for example: slag-disintegration for the reclamation of precious metals.
Typical fields of application:
Mining and steel industries: Ores, coal, coke, slags
Ceramics: Steatite, sintered ceramics, electrotechnical porcelain, fire-proof clay
Rocks and soils: Bauxite, slags, quartz, clinker, gypsum, chalk
Glass: Frits, glass types, raw materials
Soil research: Dried soil samples, sewage sludge, hydrological sediments, drilling cores
Method of operation:
The material to be ground is crushed between two counteracting grinding disks with course radial toothing on the inside as a result of compressive and shearing stresses. The staged toothing means that the material is preground in the inner chamber of the grinding disks before being finely ground in the outer chamber.
The gap width between the two grinding disks is set from the outside – also during operation – and determines the fineness of the end product.
Features of performance:
- reproducible grinding results through accurate gap setting (exactly 0.1 mm)
- precision adjustment for setting gap
- sight glass for checking gap width
- centrally located toggle-type fastener for grinding chamber
- divided, hinged grinding chamber
- 4 different materials for grinding disks, to ensure that contamination of the samples through abrasion of the grinding elements is avoided during processing.
- grinding disks easily accessed and replaced
- life expectancy of grinding disks can be doubled by changing the rotational direction of the motor
- simple cleaning and dust-free grinding due to dust exhauster connection
- continuous fine grinding from 85 mm to 0.1 mm in a single process through combination with the Jaw Crusher PULVERISETTE 1
- can be adjusted to individual throughput requests (optional conversion)

Sieve Shakers and Laser Particle Sizers for particle size determination
FRITSCH with their vast experience in the particle sizing field offers Sieve Shakers as well as Laser Particle Sizers in different version.
FRITSCH offers due to its equipment varieties for each special use and application a particle size measuring instrument, which uses the most modern laser technology or the well-tried and reliable sieving method and this with an unbeatable price-to-performance ratio.
Laboratory instruments for analytical sample handling
The FRITSCH instrument range also includes sample divider and feeder, because representative sample dividing of dry samples or suspension as well as controlled and uniform sample feeding for mills and other instruments are basic conditions for reliable and precise analysis.
In addition to the complete programme of laboratory instruments, FRITSCH also offers a comprehensive range of services with Workshops, product presentations with the FRITSCH-Mobile laboratory bus on your door step, test milling or particle size analysis of your sample at no charge and much more.
Please use our instrument search engine and our grinding report data base on the FRITSCH-Homepage under www.fritsch.de – sample preparation – solutions. Here you will find your suitable instrument as well as a comparative grinding report comparable with your application.
