Fast pre- and fine-grinding in one instrument
The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 premium line offers impact, shearing and cutting comminution in one instrument – with a higher performance, better cooling and is significantly quieter than comparable instruments.
Its powerful motor is ideal for the particularly fast comminution of soft to medium-hard, brittle as well as fibrous materials and temperature-sensitive samples with an extremely fast sample throughput of up to 15 litres and more per hour, depending on the material and parameter settings. Even particularly hard and fatty materials such as feed pellets can be easily comminuted with the PULVERISETTE 14 premium line. Samples which are difficult to grind or extremely temperature-sensitive (e.g. plastics) can be embrittled with the addition of liquid nitrogen and subsequently ground in the PULVERISETTE 14 premium line.
The heavy-duty motor and especially durable ceramic bearings ensure a particularly high impact and rotor speed with an extra powerful 22,000 rpm.
Your advantage: finer results in shorter times. Due to its high performance, the PULVERISETTE 14 premium line is the ideal Variable Speed Rotor Mill for comminution at pilot plant-scale in the plastics industry.
The Pulverisette 15 cutting mill is suitable for the grinding of soft to medium to hard dry materials such as animal feeds, bones, fibres, wood, non-metallic waste, dried meat and straw, with a maximum feed size of 60mm and a throughput of up to 50Kg/hour. This cutting mill may be used to mill a minimum sample quantity of approximately 50g.
The Pulverisette 15 cutting mill contains a grinding chamber, which contains three fixed blades to effect size reduction. The processed material remains in the grinding chamber until the desired particle size has been achieved before passing through a sieve cassette into the collecting vessel. The specific particle size is achievable with the different sieve cassettes ranging from 0.25mm to 2mm with trapezoidal perforations and 4mm to 6mm with square perforations.
The Pulverisette 19 cutting mill is the next model up from the Pulverisette 15 cutting mill and is suitable for the grinding of soft to medium to hard dry materials, with a maximum feed size of 70 x 80mm and a throughput of up to 60Kg/hour. The Pulverisette 19 is a very versatile cutting mill and may be used to mill the following: animal feeds, bones, fibres, wood, non-metallic waste, dried meat and straw.
The grinding chamber of the Pulverisette 19 houses a rotor, which in combination with the three fixed blades (in the grinding chamber wall) gives the initial material size reduction. The three fixed blades are set at different angles, which means that the material is both crushed and ground before it is carried (by the permanent air flow through the instrument) to the sieve cassette. Sieve cassette sizes for the Fritsch Pulverisette 19 cutting vary from 0.25mm through to 6mm.
The Kinematica Polymix mill has been specifically designed for the processing of dry small sample volumes 10-100ml and may be used to prepare a range of sample materials including: foodstuffs, animal feed, textiles, leather and bones. The Kinematica PolyMill Mill can be used with either a cutting or hammer mill attachment, making this a very versatile, compact sample preparation instrument.
During operating, the sample material is spun around the grinding chamber until the desired final fineness is achieved, by passing the sample material through a sieve mesh, before it is passed into the collection tube. Sieve mesh sizes vary from 0.2mm to 6mm
