2.2  Scope of application

NOTICE!
The PULVERISETTE 14 premium line has been built

according to the state of the art and in accordance with rec-

ognized safety rules. During operation, however, hazards

can arise for users or third parties and damage to the

machine or other material property can occur.

The PULVERISETTE 14 premium line allows the fast comminution of soft

to medium-hard samples, such as:

Plants

Wood

Roots

Leaves

Needles

Spices

Pharmaceuticals

Dragées

Pills

Textiles

Leather

 

Chemicals

Fertilizer

Food

Grains

Feed pellets

Plastics

Pulp

Filler

Chalk

Kaolin

Coal

 

After embrittlement with liquid nitrogen:

Synthetic resins

Foils

Plastics (PVC, PP, PE)

The extremely high-speed PULVERISETTE 14 premium line enables the

comminution of temperature-sensitive ductile or plastic samples. By

simultaneously adding liquid nitrogen, samples that are extremely diffi-

cult to mill, such as soft PVC foils, can be made fine enough for analysis.
For iron-free grinding, the rotor and sieve used are made of titanium.

The inside of the mill, typically made of chrome-nickel stainless steel, has

been suitably coated with a relatively abrasion-resistant PTFE layer. The

grinding insert made of pure titanium is only for use with "soft mate-

rials". Hard substances destroy the sieve ring and drastically reduce the

service life of the rotor.
