With a maximum feed size of 25 mm and a variable rotor speed of 500-6000 rpm, the FRITSCH Mini Cutting Mill PULVERISETTE 29 comminutes quickly and powerful medium-hard, soft, tough, fibrous, tough-elastic and temperature sensitive materials such as grain, seeds or even plastics and other materials with a low specific density with reliable reproducible results. Due to the variable rotational speed adjustment between 500 and 6000 rpm you can fine tune the comminution process for each sample. And like all FRITSCH Cutting Mills, the Mini Cutting Mill is also unmatched in regards to simple and fast cleaning.
The rotor knives as well as the fixed knives are turnable and therefore particularly durable. The handling couldn‘t be easier, since rotor and fixed knives are simply inserted. An adjustment of the cutting gap is not necessary.
WORKING PRINCIPLE
Unique grinding chamber geometry
Another advantage of FRITSCH Cutting Mills is their special grinding chamber geometry: Thanks to a progressively designed cutting geometry between the rotating cutting edges of the rotor and the fixed knives in the grinding chamber, the sample material is automatically transported away and thereby comminuted increasingly fine by shearing forces between the knives until the desired final fineness is achieved. In addition, the practical FRITSCH sieve inserts always automatically ensures the optimal distance to the rotor – and since there are practically no dead spaces, the sample material cannot come to a rest anywhere.
FEATURES
Fast, reproducible comminution due to high variable cutting rotor rotational speed 500 - 6000 rpm
48,000 cutting processes per minute
Max. feed size 25 mm
Defined final fineness due to interchangeable sieve inserts – 0.25 – 6 mm
Easy, fast and thorough cleaning of the grinding chamber and of all cutting tools
Exceptionally long service life through use of turnable rotor and fixed knives
Ideal for analysis of moisture, raw fibre and ash as well as for IR and NIR
Thanks to its variable rotational speed, the FRITSCH P-29 comminutes especially grain and other seeds in an optimal way and with almost no loss of moisture. It thus fulfils the essential requirement for analytically correct analysis in the area of feed and raw material sampling.
Particularly powerful
Effective comminution
The rotor with 4 straight cutting edges and fixed knives made of hardened stainless steel enable up to 48,000 cutting processes per minute. When it comes to the selected materials, we made sure to choose particularly high-quality materials and paid particular attention to processing.
Defined final fineness
Various sieve inserts made of stainless steel 316L with either square or trapezoidal perforation enable you to achieve a final fineness of 0.25 – 6 mm.
SIMPLE CLEANING
Unmatched easy cleaning!
The Mini Cutting Mill can be cleaned contamination-free in few simple steps. Andthe sieve inserts with square and trapezoidal perforation made of stainless steel 316L ensure with less dead space additionally a clearly simpler cleaning.
Removable wear-free labyrinth seal for fast, residue-free cleaning
The labyrinth seal made of stainless steel – on the shaft - is wear-free and offers effective contamination protection and no additional heat effect for your samples.
EQUIPMENT / ACCESSORIES
Configure your Mini Cutting Mill PULVERISETTE 29 exactly to your specific application
The Mini Cutting Mill PULVERISETTE 29 is equipped with 5 sample cups 100 ml. We offer a funnel with pusher, cutting rotor and sieve inserts, which need to be ordered separately. Our sieve inserts with trapezoidal and square perforations determine the final fineness of the sample and can be inserted quickly and easily and ensure automatically a constant distance between rotor and sample material.
