Pulverisettes: Cutting Mill "pulverisette 15"

For grinding of soft to medium-hard, dry samples as well as fibrous materials or materials containing cellulose.

Typical fields of application:
rubber, leather, paper, cardboard, tissue, plastics, wood, non-metallic waste, coal, animal feeds (also pellets), maize, grain, confectionery, malt, farinaceous products, spices, dried meat, bones, horn, dragées, tablets, leaves, fibres, peat, roots, tobacco, cork, straw, film and similar materials, which can be introduced irrespective of length.

Method of operation:
In the grinding chamber of the laboratory cutting mill "pulverisette 15", four knives rotate against three stationary knives in the cutting action to reduce the sample. The material remains in the grinding chamber until the final particle size desired is achieved and the continuous flow of air carries it through the mesh of the interchangeable sieve insert into the collecting vessel.

Features of performance:

- Easy access to grinding chamber using only two knurled screws
- Housing with cover opens out completely and cover can be removed from hinge
- 2-litre stainless steel funnel with plastic pusher
- Long lasting hardened steel knives and cutting edges can be reused
- Knives can be resharpened
- Cutting gap externally adjusted
- High cutting rotor speed (2800 rpm)
- Designed for operation either fixed to bench-top or for use on independent mounting frame
- Defined final particle size with interchangeable sieve inserts
- Easy cleaning of grinding chamber and grinding parts
- Certified safety (CE mark) and 2 year guarantee


Equipment: 

The Cutting Mill is equipped with a 3.5 litres collecting vessel, but without sieve insert. Sieve inserts are available with different trapezoidal and square holes and must be ordered as accessories. If a collecting vessel 30 litres is desired instead of 3.5 litres, so it is possible to deliver the Cutting Mill with a 30 litres collecting vessel. This must be note accordingly on the order.
