Impact Mill Condux®

Simple, flexible grinding!

The Impact Mill Condux® is a high speed fine impact mill for the dry grinding of various products up to a Mohs hardness of 3 - 3,5. The diversity of grinding tools allow the mill to be used universally depending on the application and area of operation. This of course also applies later on, when circumstances such as product characteristics or requirements have changed, the grinding tools can be changed as well.

Depending on the application and product, the mill is equipped with differing rotor and stator variations and can be operated as any of the following mill types: Pin Mill, Blast Mill, Beater Mill or Attrition Disc Mill.

One design variant with 2 housing doors can be used either as a single rotor or a counter-rotating pin mill.

Impact Mill Condux® with integrated Classifier

The newly designed Condux® Impact Mill with an integrated dynamic air classifier is used when the desired final fineness cannot be achieved with conventional screenless pin mills or blast mills with screen inserts. In contrast to conventional classifier mills, the grinding disc and classifier wheel are torque-proof connected to each other and are operated by a common drive motor. By adjusting the height of the classifier wheel, it is possible to achieve a variable setting of the separation limit in a simple way.

With the Condux® CP, high finenesses (< 30 µm) and exact upper particle size limitation can be achieved.

  • Simple housing design ensures fast cleaning of the machine
  • The grinding disc and classifier wheel are torque-proof connected and are operated by a common drive motor
  • The height of the classifier wheel can be easily adjusted to allow variable adjustment of the cut-off point

Impact mill Condux® Compact

Simple Sugar Grinding – ATEX-compliant

The grinding of products, whose dusts are potentially explosive, places particularly high demands on the technology used and the design of a grinding plant with regard to safety. The most frequently used variant is a complete grinding system which is pressure shock resistant up to 10 bar (g). However, this usually means considerable costs for peripheral equipment.

With the new ATEX-compliant plant concept Condux® Compact, the installation of a more efficient grinding plant for many products is considerably easier: With this newly developed plant concept, explosion protection valves or explosion suppression equipment, explosion-decoupling devices, ventilators and even dust filter systems are no longer required in the classical sense.

Processing and refining are the actual tasks of the spice industry - a product which is "suitable for consumption" must be manufactured from the raw spices. One of the main tasks is the grinding of the raw materials. As the flavoring components - mainly essential oils - are very volatile, a particularly gentle grinding procedure must be used.


Sugar is a versatile raw material used to manufacture chocolate, jams, ice cream, beverages or bakery products such as cookies. For many applications, sugar is finely ground to increase the rate of solubility or simply for the decoration of tasty desserts.


Typical toner products have a D50 in the range of 5 µm – 7 µm. NETZSCH Trockenmahltechnik GmbH entered the field of toner processing with the development of the CGS Jet Mill in the 1990’s followed by the CFS/HD-S High Dispersion Air Classifier a few years later.


As the global leader in particle-reduction machinery, NETZSCH offers the technology and machinery to provide true drug development solutions.


In contrast to conventional grinding plants, the processing gas in the new Impact Mill Condux® Compact is circulated. A pressure shock resistant rotary valve feeds the product directly into the mill. After the product has been ground, it leaves the machine through another valve at the bottom of the mill.


Condux® fine impact mills can be used for a wide range of applications. Equipped with various grinding tools and stators, optimum adaptations to different processes are guaranteed, also for pressure-shock-proof, inert gas and cryogenic grinding plants.


Our long-term experience with a diversity of products in these fields, is available for your toll grinding needs.

Mills and classifiers for processing cellulose


The demands placed by the manufacturing industry on the technical design of mechanical plants and processes are getting tougher all the time. Gas-tight or surge pressure-resistant designs are already a must for most plant and machinery to ensure compliance with the latest regulations. New product qualities and/or methods of production also enlarge the portfolio of requirements, for example in the cellulose processing sector.

Application literature

Whether used for the fine icing on cakes and cookies, in the production of confectionery and drinks, or for the visual rounding off of delicious desserts, in our latitude we cannot imagine a life without white sugar crystals for the sweetening of foodstuffs. Apart from the "coarse" crystal sugar or refined sugar which is mainly used, the considerably finer form of sugar, icing sugar, is required for many applications in the household and in industry. The manufacture of this fine sugar is carried out by mechanically milling sugar crystals on modern impact mills.
