Technical specifications

Machine type designation: ZM200

Intended use

The Retsch Ultra Centrifugal Mill ZM200 is deployed for rapid fine

grinding of soft to medium hard and fibrous materials up to a

grain size of 10 mm.

See the section in the chapter on "Operation" below for

examples:

"Unsuitable comminution material"

"Suitable comminution material"

"Comminution methods"

"Comminution by cold grinding"

The end fineness achievable is determined by :

The type of rotor

The speed of the rotor

The ring sieve

The shearing properties of the comminution material

The effective grinding technology and the extensive range of

accessories mean that the ZM200 can quickly prepare samples

ready for analysis in a way which preserves the material.

It is not designed as a production machine, but rather as a

laboratory device intended for single-shift, 8-hour operation.

Do not make any modifications to the machine and only use Retsch

approved spares and accessories.

The conformity to the European guidelines declared by Retsch

otherwise loses its validity.

It furthermore leads to the loss of all warranty claims.

Do not fill too much into the collecting container. Do not exceed a max.

1/3 of the filling capacity.

Excessive filling can cause overheating and damage to the plastic

housing.

Max. 5000 ml with components obtainable as accessories

Maximal feed grain size

Up to 10 mm

Maximal end fineness achievable

< 40 µm, in dependence on the feed material and ring sieve

Drive output
