Typical areas of application:
rubber, leather, paper, cardboard, fabrics, plastics, wood, metal-free waste, coal, animal fodder (also pellets), maize,
grain, sweets, malt, pasta, herbs, dried meat, bones, dragées, tablets, leaves, fibres, peat, roots, tobacco, cork,
straw, films etc.
Procedure:
The samples to be ground are milled using a rotor fitted with knives in combination with three stationary knives.
Performance features:
- rapid, reproducible grinding
- easy, quick and thorough cleaning of the milling chamber and all milling components
- various rotors for adapting the cutting performance to the samples
- cutting rotor and sieve cassette/inserts can be removed and exchanged without tools
- adjustable exterior cutting gap
- hinged housing for easy access
- vacuum connection for dust extraction
- safety tested (CE-mark)
- 2 year warranty
Four different models are available with various feed particle sizes and throughput quantities.
The Universal cutting mill Pulverisette 19 and high-power cutting mill Pulverisette 25 can be combined. This allows
samples of up to 120mm maximum feed size to be ground to a particle size of only 100µm within a short space of
time and in a single process. Ordering information for cutting mill combination is available on request.
