Laboratory Grinding Mill Offers Rapid Results
The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 rapidly and effectively grinds soft to medium-hard, brittle and fibrous samples, making it a valuable addition to any processing or lab set-up.
The highly efficient air cooling and cyclone technology makes even the comminution of difficult to grind samples such as temperature-sensitive powder coatings and plastic samples or slightly moist materials such as herbs, leaves or teas easy.
Air routing system
The laboratory grinding mill has efficient air routing and the powerful air vortex of the FRITSCH Cyclone cool samples during grinding. This reduces the thermal load, minimising sieve ring clogging and improving throughout significantly. This also means that cleaning time is greatly reduced.
Thanks to the cyclone technology utilised in the PULVERISETTE 14, the ground sample is led directly into the screwed-on sample glass to be easily transported, stored and removed for analysis. This is just one way the FRITSCH rotor mill advances usability.
Fine dust is retained in the cyclone by the HEPA dust filter, giving increased grinding performance for fast and effective laboratory grinding with minimal thermal load.
This sample grinder is the ideal solution, particularly for heat-sensitive materials, as well as for smooth pre-crushing and fine grinding of hard-brittle or soft, fatty samples that hold residual moisture.
Extremely difficult to grind or acutely temperature-sensitive samples such as styrene, polyester styrene, polyester, synthetic resins, foils, PVC, PP and PE can be embrittle with liquid nitrogen and then ground.
And all this with a simple, contamination-free operation and low cleaning effort..
There are many more advantages of the variable speed rotor mill too.
Sample throughput is rapid and ease of use is further enhanced by the simple exchange of all grinding parts without the need for tools. Contamination-free cleaning and assembly of all grinding parts is also easy and takes place outside the instrument.
The speed is adjustable from 6,000 to 20,000 rpm, the maximum feed size is 10 mm and the grinder can handle small sample quantities down to 5 ml.
A final fineness of d50 < 40 µm can be reached with sieve inserts of 0.08 - 6 mm.
Constant laboratory grinding is available with the automatic rotational speed readjustment system and with grinding parts manufactured from stainless steel, pure titanium, TiN-coated and WC-coated, the grinding mill is durable and reliable too.
