NETZSCH Trockenmahltechnik GmbH, one of the global leading companies in the area of dry product processing, is part of the Business Unit Grinding & Dispersing of the NETZSCH Group. Customers profit from our comprehensive experience potential and our diverse machine program, ranging from laboratory- and production machines to complete production lines. Fine impact mills, classifying- and jet mills as well as fine-cutting mills and high-efficiency fine classifiers made by NETZSCH are mainly used in the application areas chemistry, inorganic materials/minerals, ceramics and life science for pharma-...

NETZSCH Trockenmahltechnik GmbH NETZSCH Trockenmahltechnik GmbH’s headquarters are based in Hanau am Main. Here, as well as administration, R&D, process engineering, production and sales departments, one of the most state-of-the-art application laboratories in grinding- and classifying technology is also available for customer tests. This was extended in 2015 to include a FOODLAB for tests under food-grade conditions. At the production location in Stockach near Konstanz on Lake Constance, filters and cyclones are manufactured, which are either integrated in plants at Hanau or delivered directly...

NETZSCH Jet Mills In jet mills the size-reduction of particles is carried out in a gas jet. The grinding gas (air or argon, N2, ...) is guided into the grinding chamber and accelerated in such a way, that product particles are carried along in the gas flow and impact against each other. Size-reduction is autogenous and contamination is therefore low. Jet mills are predestined for grinding dry- and very hard materials to obtain a particle fineness in a range of 0.1 µm to 100 µm. With the CGS fluidized bed jet mill and the CONJET® high-density bed jet mill, which are both equipped with a dynamic air...

Application Example: Superfine products in the submicron range The S-JET® grinding process is opening new doors for the dry manufacture of products with particle sizes in the submicron range and an exact particle size distribution. The basic requirement is a grinding product which is thermally resistant. Many different products, such as minerals, ceramics, pigments and raw materials for batteries are already processed on the S-JET® steam jet mill. This unique process has provided access to completely new application possibilities. x (diameter) / µm Particles size measuring method CILAS 1064 wet...

NETZSCH Impact Mills In general, rotary impact mills are used for the grinding of soft products to products with medium-hardness (up to hardness 3 on Mohs scale) with a fineness of several mm down to a one-digit µm-range. These mills are equipped with a rapidly-running rotor with suitable grinding tools around which grinding tracks, screens or counter-rotating pins are used as an impact partner. The CONDUX® fine-impact mill can be used in a broad range of applications. This mill can be optimally equipped with various grinding tools and stators to suit the grinding product and it can also find use...

Application Example: Cathode Masses for Lithium-Ion-Batteries Lithium ion batteries store and supply electrical energy in cell phones, laptops and tools. Electrical vehicles, such as bicycles, scooters and other hybrid concepts are also creating a steadily rising demand for batteries. The goal is to develop increasingly powerful batteries whose features are higher capacity, longer lifetime, shorter charging times, and lower weight and size. With the CERAMIC-execution of the CSM classifier mill, dry-grinding of battery masses free from metallic contamination of the ground product is possible! All...

NETZSCH Fine-Cutting Mills Cutting mills are used to grind and homogenize medium-hard to soft and elastic materials. In this process the material is ground by shearing forces using rotary- and stator knives. As a rule, the material is fed into the machine from above, it falls onto the rotor and is ground between rotor- and fixed cutting knives. As soon as the material has reached the desired fineness, it can leave the grinding chamber via the screen in the lower part of the machine where it then falls into the collection vessel. Cutting mills made by NETZSCH are characterized by their robust design,...

Application Example: Cellulose and Cellulose Derivates Before cellulose and cellulose derivates can be used in food and pharmaceutical products, they must undergo multistage processing. With the CS-Z, SECOMY® and SECOMY® S finecutting mills, which exhibit precise and high cutting frequency and are equipped with a screen insert and/or a rotating classifier wheel for determining the discharge size, NETZSCH can offer the ideal solution for the first step. A cellulose powder, which can be used straight away as a filler or additive to the product (foodstuffs) is obtained. The powder obtained can also...
