Patented power team
With the extra powerful, patented FRITSCH Cutting Mill Combination of the Universal Cutting Mill PULVERISETTE 19 large with variable rotational speed of 50-700 rpm and the Universal Cutting Mill PULVERISETTE 19 with a variable rotational speed of 300-300 rpm, as well as the associated FRITSCH high-performance Cyclone separator, it is possible, for example, to process 2 litres of sample material with a particle size of 30 mm in only one single step.
It doesn‘t matter how heterogeneous the sample is – even household waste, construction waste, German recycling system bales or light shredder fractions from automobile recycling: Within five minutes, our extra-powerful double mill will reduce any of these materials into a representatively divided analysis sample with a final fineness of < 500 μm! This is the ideal solution for inexpensive preparation of heterogeneous materials for analysis according to the Technical Instructions on Municipal Waste (TOC) or for determination of the calorific value and chlorine content.
WORKING PRINCIPLE
Operating principles of the powerful FRITSCH Cutting Mill Combination
The extra powerful FRITSCH Cutting Mill Combination consists of the Universal Cutting Mill PULVERISETTE 19 large with variable rotational speed of 50-700 rpm and the Universal Cutting Mill PULVERISETTE 19 with a variable rotational speed of 300-3000 rpm. The entire sample is pre-crushed by the PULVERISETTE 19 large then falls automatically through a funnel into a sample divider which divides the sample according to a 1:13 ratio by default. The division ratio is variable.
This smaller sample is then automatically comminuted in the PULVERISETTE 19 down to a final fineness of 0.2 mm and drawn into the collecting vessel by the connected FRITSCH high-performance Cyclone separator.
Through selection of the cutting tool sets and sieve cassettes, the FRITSCH Cutting Mill Combination can be individually adapted to any specific application. All accessories of the PULVERISETTE 19 large and PULVERISETTE 19 are available for this.
