Milling - Dispersing Homogenising
The pulverisette 14 is the all-purpose mill for rapid crushing of medium-hard to soft substances. It can also be used to disperse and homogenise dry samples. Grinding temperature-sensitive materials is also no problem for the variable speed rotor mill. The extremely high rotor speed enables fast and effective grinding, drastically reducing thermal stress on the grinding material.
Samples that are difficult to grind can be ground to analytical fineness by embrittlement (e.g. addition of liquid nitrogen before grinding). Under some circumstances, the high efficiency of the mill can make it possible to grind such samples even without previous embrittlement.
The "pulverisette 14" can be fitted with a pin insert in order to grind medium-hard samples and materials containing oil or grease without a sieve.
By inserting an impact rotor with impact blades in the sieve ring, hard to medium-hard samples can be crushed easily through the increased shearing effect.
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 kg per hour.
The Variable Speed Rotor Mill pulverisette 14 with a real top speed of 20.000 rpm is the Turbo Mill for sample preparation. Rotors, sieve rings and collecting vessels made of different materials and in different sizes enable an optimal adjustment of the system to the application.
