Variable 50 – 700 rpm for powerful comminution of larger amounts
The PULVERISETTE 19 large is our powerful low-speed Universal Cutting Mill for fast reproducible comminution of hard, tough-elastic and temperature sensitive materials and plastics with a maximum feed size of 120 x 85 mm and a throughput of up to 85 l/h with a low rotational speed of 50-700 rpm and a maintenance-free 2.8 kW three-phase motor with frequency converter. เครื่องบดตัวอย่างแบบใช้ใบมีดตัด
Due to the variable rotational speed adjustment in increments of ten between 50 and 700 rpm and a torque of up to 67 Nm enables the PULVERISETTE 19 large due to the combination of low cutting rate and extreme cutting forces a very powerful comminution.
At the same time, it is the ideal solution for all cases where e.g. thermal damage, the loss of highly volatile substances, or an excessively high fine share need to be avoided. And the PULVERISETTE 19 large is also ideal for RoHS tests. Due to Clean Design the PULVERISETTE 19 is quickly and simply cleaned and offers a reliable protection against cross-contamination.

Unique grinding chamber geometry
The sample material is comminuted according to the cutting principle of scissors between the cutting edges of the rotor and the fixed knives in the grinding chamber until the desired final fineness is achieved. Unique grinding chamber geometry: The grinding chamber is designed with minimal dead space and progressive cutting geometry between rotor and fixed knives. The sample material is continuously moved during comminution and cannot settle anywhere. In conjunctions with the special air flow, this is the basis for swift, blockage-free operation and fast cleaning without residue.
Running stabilisation due to flywheel mass
The Universal Cutting Mill PULVERISETTE 19 large is equipped with a flywheel mass to stabilize the drive torque. This ensures stable operation even for extreme short-term load, as well as an optimal comminution result.

Unmatched easy cleaning!
While you are still tightening the screws on other mills, your FRITSCH Cutting Mill is already clean. Because with just a few simple motions the entire grinding chamber can be opened and rotor and sieve cassette can be removed without tools. The housing and lid can be lifted back completely, and the grinding chamber lid can be completely removed from the hinges.
The result: a completely open empty grinding chamber with minimised dead space for easy quick cleaning and safe protection against cross-contamination.
FRITSCH-Plus: The sieve cassettes with square perforation made of stainless steel 316L are laser welded and ensure with less dead space a clearly simpler cleaning.
Removable wear-free labyrinth seals for fast, residue-free cleaning
The labyrinth seals made of stainless steel – on both sides of the rotor as well as on the shaft and in the lid – are wear-free and offer effective contamination protection and no additional heat effect for your samples.
Effective comminution with dry ice and liquid nitrogen
Due to the well-conceived instrument design and the materials used, it is no problem to comminute pre-cooled materials or samples embrittled with liquid nitrogen.
The improved breaking behaviour enables efficient comminution also of sticky, tough-elastic or temperature-sensitive materials with dry ice or after previous embrittlement of the sample with liquid nitrogen.
Complete operation at the front
The well-designed control panel keeps all functions, including the on/off switch, easily accessible on the instrument’s front panel. The rotational speed is set in increments of ten with the plus/minus buttons and shown on the digital display.

COMMINUTION OF HETEROGENEOUS MATERIALS IN THE CEMENT INDUSTRY
The manufacturing of cement is a very energy intensive production. Here for the most part coal is utilized as an energy carrier, but in the future the use of secondary fuels will increase and also the need of the analysis of such materials.
COMMINUTION OF SILICONE RUBBER
Many industries rely heavily on silicone rubber as a basic material. Effective for the sample preparation of the material are the FRITSCH-Mills.
INSPECTING NATURAL RUBBER ANALYTICALLY
The production of homogenous composite samples is a prerequisite. Latex the white milky juice of the rubber tree, is sold in liquid or solid form as natural rubber. For the production of the liquid state, the tree juice is thickened and stabilized with ammonia. For the production of the solid state, the suitable chemicals are added to the juice of the plant and will coagulate. This solid is washed in various ways, dried and shaped mostly into thin slabs.
PREPARING LEATHER FOR CHEMICAL TESTS
Leather is produced by tanning of skin. Modern technologies of the leather production ensure that the leathers are available contaminant free. FRITSCH Cutting Mills are perfect for the sample preparation of leather for further tests.
FOR QUALITY CONTROL PURPOSES NUTS HAVE TO ENDURE A GREAT DEAL
Routine quality inspections of nuts in production and trade are subject to clear regulatory requirements. The following article contains compact information about the requirements, as well as aspects of the sample preparation of nuts with FRITSCH cutting mills.
VANADIUM – A METAL WITH UNLIMITED FIELDS OF APPLICATION
Vanadium – a transition metal with special potential. An interesting topic which for example is broadened through the possible uses of vanadium in the energy transition. In this article, the material properties of vanadium are discussed and the sample preparation described.
COMMINUTION OF PUNCHING WASTE
Non-ferrous metals punching waste respectively recycling materials accrue during the production of electronic components. The production of representative samples can simply be achieved with FRITSCH Cutting Mills.
SAMPLE PREPARATION FOR THE ANALYSIS OF SECONDARY FUEL IN CEMENT PLANTS
Secondary fuel can be a very inhomogeneous sample, containing all types of polymers, paper, wood and low fractions of metal. Also recycled wood or parts of automobile tires might be used as secondary fuel. Before using it as fuel in the production of cement, several chemical analyses are necessary as quality control.
YOUR CELL PHONE TURNS INTO DUST
For the sample preparation for the RoHS analysis, several steps are necessary in order to achieve the desired degree of fineness. Optimal here are FRITSCH Mills.
