Variable Speed Rotor Mill – the all-purpose mill for rapid comminution

FRITSCH Variable Speed Rotor Mill PULVERISETTE 14 Before and After Grinding

Highest rotational speed for finest grinding results in shortest times - ideal for grinding of tablets, dragées and pharmaceuticals

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, we have developed the FRITSCH-impact blades: Due to its clever design it allows together with a sieve ring a very gentle grinding of the sample, which in many cases without impact blades would not be possible. The result: Increased grinding action for a particularly fast and effective grinding, the heat load is minimized. And 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!
