Variable Speed Rotor Mill Pulverisette 14 premium line
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.
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.

ACCESSORIES FOR USE AS VARIABLE SPEED ROTOR MILL
For standard applications choose the extremely durable, low-wear impact rotor with 6, 12 or 24 ribs with cooling fins made of stainless steel, as well as sieve rings with trapezoidal or square and round perforation from 0.08 mm to 6 mm with reinforced edges made of stainless steel 316L for the desired final fineness.
For grinding in the analytical sector, food and pharmaceutical industry please choose select grinding tools made of stainless steel 316L.
For heavy-metal- and iron-free grinding and sample preparation according to RoHS please select impact rotor and sieve ring made of pure titanium.
Difficult-to-mill or temperature-sensitive samples and plastics
ACCESSORIES FOR USE AS CUTTING MILL
For standard applications of pre- and fine comminution of fibrous materials and plastics select the cutting rotor made of stainless steel.
The cutting rotor made of hardmetal tungsten carbide comminutes hard-tough materials. Choose in both cases additionally sieve shells with trapezoidal, square or round perforation made of stainless steel 316L.
For heavy-metal- and iron-free grinding and sample preparation according to RoHS use the cutting rotor with cooling fins and sieve shells holder made of stainless steel TiN-coated.
For comminution of soft materials choose rotor edges and fixed knives made of pure titanium and for hard-tough materials we recommend rotor edges and fixed knives made of zirconium oxide. Choose in both cases additionally sieve shells with trapezoidal perforation made of stainless steel TiN-coated.
SAMPLE EXHAUSTION WITH CYCLONE SEPARATORS AND FOR GRINDING LARGE QUANTITIES
FRITSCH Cyclone separators ensure with their powerful airflow simple feeding and faster throughput. The powerful airflow enables the use of finer sieve rings to achieve a higher final fineness. The cyclones are ideal for even for temperature-sensitive samples and materials which are otherwise difficult to grind finely, such as electrostatically-charged plastics or powder coatings. Two models are available: High performance Cyclone separator and small volume Cyclone separator.
