Toll Grinding in Hanau

As part of it's customer oriented focus, mill manufacturer NETZSCH-CONDUX Mahltechnik in Hanau, Ger-many, has renovated it's laboratory and commissioned a toll processing facility. For this purpose, new plants have been installed:
A grinding plant with a Fluidized Bed Jet Mill CGS 71, in which the mill housing as well as the conveying pip-ing are lined with aluminium oxide ceramic, guarantees an absolutely (metal-)abrasion-free product processing. In order to also process dust-explosive products, the complete grinding plant has been executed in pressure shock resistant design up to 10 bar(g). 

In addition to this, the recently developed and energy-saving grinding process e-Jet® system, for which a patent has already been applied, has been installed. 

The CONDUX CSM 360 classifier mill system used for fine-grinding of a wide variety of materials, including industrial minerals, powder coatings, chemicals and food products. This machine combines impact grinding tools with an integrated, dynamic air classifier to achieve final particle sizes of less than 10 µm. The actual grinding occurs between a rotor and peripheral grinding track. Internal and external process controls provide stable operation and consistent product quality.
The CONDUX CS 500/1000-Z fine cutting mill used mainly for the production of free-flowing cellulose powder. Cellulose rolls or sheets can be fed directly into the cutting granulator. Pre-cut bales can also be processed. In addition, this versatile machine is capable of finely cutting various other, non-brittle materials.

The feed product is cut between high-speed rotor knives and stationary knives in the housing. A specialized screen in the lower part of the machine housing determines the final size of the powdered product. The most common finenesses are between approx. 0.2 and 1 mm. This machine can be equipped with varying numbers of knives and screens depending upon the product and application!
