Process Technology for Ceramic Applications - 2

Ceramic applications have become indispensable in the modern world. They are used wherever conventional materials reach their limits. be it wear resistance. heat resistance. biocompatibility or even special electrical properties. Ceramic materials can always be selected specifically for the particular application. for example heat-resistant components in space travel or the inrun of a ski jump. Because of their versatility. ceramics are used more often than one would expect. Mixing and grinding down to the submicron range - as a laboratory machine. stand-alone machine or even as a complex...

Process Technology for Ceramic Applications - 4

Whether at home or on the move. in the office or even in production. parts and components made of high-tech ceramics can be adapted to a wide variety of applications. Where other materials reach their limits. high-tech ceramics are employed. Hardness. wear resistance and temperature resistance are the properties that matter. But it is precisely these properties that demand top performance from our production machines. For this reason. the machines must always be specially adapted to the particular requirements as well. e.g.. purity. hardness or wear protection. Wet mills in this area are...

Process Technology for Ceramic Applications - 6

Utility ceramics have been with us for thousands of years and are ubiquitous in our daily lives. Utility ceramics is the term used to describe any ceramic that has been created to support us in our everyday lives. Since these are mostly mass-produced goods, grinding units with a high throughput capacity are used. Starting materials for utility ceramics are mainly ground natural minerals. Coating compounds for protection or decoration, are a large area of application for the NETZSCH agitator bead mills, for example, the Discus® series.

Process Technology for Ceramic Applications - 8

Whether for grinding. polishing or wear protection. only the hardest ceramics are used here. The most important representatives are oxides. nitrides and carbides. The correct choice of grinding process and grinding chamber lining are the decisive factors. For dry processing. the jet mill is particularly suitable. as the product particles grind each other. After grinding. our high-performance classifiers ensure separation into the various FEPA classifications. Since. in some cases. sufficiently wear-resistant grinding beads do not exist for wet mills. it is then necessary to switch to...

Process Technology for Ceramic Applications - 10

Traditional materials such as porcelain and steatite. which are used for insulators. ceramic fuses and lamp sockets. are fading further into the background. In their place. more and more electronic components such as capacitors. resistors. varistors and many others are made of ceramics. Together with the substrates. they also enable a higher degree of micronization of electronic circuits. In many of these comminution tasks. the ceramic solids should only be finely dispersed in the liquids without creating new. sharp-edged fragments. This process is called "mild dispersing". The Zeta® RS is...

In the case of catalysts, not only the carrier materials but also the active substances are finely ground. Because of their expensive active substances, these so-called washcoats must be processed with as little residue as possible. With a relatively small grinding chamber capacity and high power density, our high-performance mills such as the Neos series are ideally suited for this purpose.

PRODUCTION MACHINES for Dry Grinding SpheRho®® Agitator Bead Mill The CGS fluidized bed jet mill with integrated classifier enables low-contamination fine grinding of dry products of any hardness. Due to the special grinding principle, product grinding is completely autogenous. The comminution energy is provided exclusively by gas jets, so that there is no wear on grinding tools. An optional ceramic lining is available for wear protection. The SpheRho®® dry agitator bead mill is fed con-tinuously via a rotary feeder. A shaft equipped with exchangeable agitator tools is mounted inside the...
