Product Information

Ultra Centrifugal Mill ZM 200

General Information
The Ultra Centrifugal Mill ZM 200 is a high speed rotor mill with unmatched
performance. It is used for the rapid size reduction of soft to medium-hard and
fibrous materials.
Because of the efficient size reduction technique the ZM 200 ensures the gentle
preparation of analytical samples in a very short time. The comprehensive range
of accessories including a large variety of ring sieves and rotors as well as
collection systems makes the Ultra Centrifugal Mill a versatile instrument that can
be easily adapted to varying applications. The optional Vibratory Feeder is
load-controlled via an interface and ensures a uniform grind at maximum output
rate. When using a cyclone, the sample material is additionally cooled by the air
stream and more rapidly discharged from the grinding chamber via the cassette
pan with outlet. This effect can be increased by connecting a vacuum cleaner.
With thousands of installations, the ZM 200 has become a standard for food and
feeds, for the chemical industry as well as for agricultural testing.

Application Examples
activated charcoal, animal tissue, bentonite, bones, cereals, chemical products,
coal, coffee beans, coke, collagen, corn, dried fruit and vegetables, dried larvae,
drugs, electronic components, feed pellets, fertilizers, food, limestone, minerals,
paper, pharmaceutical materials, plant materials, plastics, powder coatings,
refuse derived fuels, rice, rubber granulate, seeds, spices, straw, ...

Function Principle
In the Ultra Centrifugal Mill ZM 200 size reduction takes place by impact and
shearing effects between the rotor and the fixed ring sieve. The feed material
passes through the hopper (with splash-back protection) onto the rotor.
Centrifugal acceleration throws it outward with great energy and it is precrushed
on impact with the wedge-shaped rotor teeth moving at a high speed. It is then
finely ground between the rotor and the ring sieve.
This 2-step grinding ensures particularly gentle but fast processing. The feed
material only remains in the grinding chamber for a very short time, which
means that the characteristic features of the sample to be determined are not
altered. The ground sample is collected in the collecting cassette surrounding
the grinding chamber or in the downstream cyclone or paper filter bag.
