Universal Cutting Mill - variable speed 50-700 rpm
PULVERISETTE 19 large
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.
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.
Optimal sample exhaustion with FRITSCH Cyclone separators
Clean, convenient, cool: Combine your FRITSCH Universal Cutting Mill PULVERISETTE 19 with a FRITSCH Cyclone separator for sample exhaustion. Its strong airflow ensures simple feeding, increases throughput, and reduces the thermal load of the samples.
At the same time, the powerful airflow of the FRITSCH Cyclone separators enables the use of finer sieve cassettes to achieve a higher final fineness – even for materials, which are otherwise difficult to comminute finely.
The result: especially fast and efficient comminution with minimised thermal load and significantly higher throughput – in addition to quick and easy cleaning.
The FRITSCH high-performance Cyclone separator completely made of stainless steel 316L is particularly indispensable in the analytical sector and in the food and pharmaceutical industries, and for the processing of heterogeneous mixtures of material, e.g. in the cement industry.
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.
