Variable Speed Rotor Mill PULVERISETTE 14 premium line

code : PULVERISETTE 14

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.
