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.
Maximum feed quantity
Max. up to 20 ml with the collection container for
minimum quantities
The max. recommended feed quantity with the standard
collection container is 300ml, which corresponds to
approx. 1/3 of the cassette’s filling capacity. If more is
filled into the cassette, the sample and the appliance
may overheat.
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
750 W / power draw approx. 1300 W
Rotor speed
Can be regulated from 6,000 – 18,000 r.p.m.
