The Perfect All-Purpose Mill for Rapid Comminution

The Fritsch Variable Speed Rotor Mill PULVERISETTE 14 grinds rapid and effectively soft to medium-hard, brittle as well as fibrous samples. Even the comminution of samples which are difficult to grind or temperature-sensitive samples like tablets, dragées and pharmaceuticals are no problem for the PULVERISETTE 14 due to its very efficient air cooling.

In addition to the special air cooling of the PULVERISETTE 14, Fritsch-impact blades have developed: a clever design which allows, together with a sieve ring, very gentle grinding of the sample, which in many cases without impact blades would not be possible. This results in increased grinding action for particularly fast and effective grinding as well as minimised heat load. The PULVERISETTE 14 is the ideal solution for especially temperature-sensitive materials such as powder coatings or plastics, as well as for smoothly pre- and fine grinding of hard-brittle to soft, fatty sample or samples with a residual moisture.

The Variable Speed Rotor Mill PULVERISETTE 14 has a top speed of 20.000 rpm and is the turbo mill for sample preparation. With a feed particle size of < 10 mm, a final fineness of up to 40 µm can be achieved. The throughput depends on the material and lies between 0.05 and 5 litres per hour. Rotors, sieve rings and collecting vessels made of different materials and in different sizes enable an optimal adjustment of the instrument to the application.

Further advantages include: simple and easy change of all grinding parts without tools; simple, contamination-free cleaning and assembly of all grinding parts outside the instrument; variable speed adjustment from 6,000 to 20,000 rpm; automatic speed following system for constant grinding; grinding parts made of stainless steel, pure titanium, TiN-coated and WC-coated; rapid-action clamping lock.
