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, which can be further increased by the use of the FRITSCH Cyclone separators.
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.
Two Mills in one instrument: With the cutting rotor you turn the PULVERISETTE 14 premium line into a Cutting Mill for fast, efficient pre- and fine comminution of soft to hard-tough, fibrous materials and plastics.
Impact, shearing and cutting comminution
Inside the Variable Speed Rotor Mill, the sample is comminuted by impacting against the ribs of the impact rotor, rotating at high speed and also sheared between the rotor teeth and the inserted sieve ring.
When using the mill as a Cutting Mill, comminution takes place by cutting and shearing between the cutting rotor and the fixed knives of the sieve shells holder.
- Powerful grinding with 22,000 rpm for particularly fast sample throughput
- Extremely high impact speed of the impact rotor (111 m/s = 399.6 km/h)
- Max. feed size < 15 mm, sample throughput of up to 15 l/h and more
- Final fineness d50 < 40 μm, sieve rings 0.08 – 6 mm
