New cutting mills offer variable rotational speed for optimal adjustment of the cutting speed to your sample material
Dec 16 2019
The new universal cutting mills from Fritsch are ideal for size-reduction for a wide range of different materials due to variable adjustment of the rotational speed of the rotor, various knife geometries, replaceable blades, practical sieve cassettes and that with an unmatched ease of cleaning.
The Pulverisette 19 high-speed universal cutting mill comminutes up to 60 l/h of soft to medium-hard sample materials and fibrous materials at a torque of up to 30 Nm with reliable reproducible results. The great advantage: The variable rotational speed adjustment in increments of hundred between 300 and 3000 rpm enables fine tuning of the comminution process for each sample within a very wide range of applications.
The Pulverisette 19 low-speed universal cutting mill with variable rotational speed adjustment between 50-700 rpm and a torque of up to 67 Nm enables due to the combination of low cutting rate and extreme cutting forces a very powerful comminution of hard, tough-elastic samples and small sample quantities. 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.
Clean, convenient and cool you can combine your Fritsch Pulverisette 19 universal cutting mills with a Fritsch Cyclone separator for sample exhaustion and an exhaust system which can be ordered in addition. The strong airflow ensures simple feeding, increases throughput, reduces the thermal load of the samples and enables the use of finer sieve cassettes to achieve a higher final fineness – even for materials, which are otherwise difficult to comminute finely. The resul is a an especially fast and efficient comminution.
The Fritsch high-performance Cyclone 304 separator, completely made of stainless steel, is particularly indispensable for the processing of heterogeneous mixtures of material, for example: in the cement industry. Due to its high surface quality, it offers enhanced resistance to corrosive media such as alkalis and acids and is especially easy to clean with a wide range of possible cleaning agents, without leaving any residues. In addition, it can be completely dismantled, fully emptied, flooded and sterilised, and thus offers reliable protection against cross-contamination.
What is especially convenient is that the comminuted sample is drawn directly into the screwed-on sample glass or in a larger collecting vessel of up 60 litres, in which it can also be transported and stored.
Especially for exhaustion of small sample quantities, we designed the compact FRITSCH small volume Cyclone separator. It is made of plastic, can be dismantled completely and cleaned in a dishwasher for reliably preventing contaminations. The comminuted sample is collected in a screwed-on sample glass of 250 or 500 ml volume.
