Dry Grinding

NETZSCH represented in Romania by Kogaion is one of the market leaders in dry grinding technology. We are your first choice for the grinding of dry products!

From A (activated carbon) to Z (zinc) – we offer the right mill for your product.

Our extensive experience and wide range of mills are available for the fine cutting, fine grinding and ultra-fine grinding of dry products of all desired finenesses.

High-performance classifiers for the finest of products, round off our program.

From individual mills to complete turnkey milling systems; non-PSR or dust explosion protected plants up to 10 BAR PSR (pressure shock resistant) and inert gas plants are available; material executions in a diversity of designs including stainless steel with polished surfaces or wear protected models – We have the perfect solution for you

Air classifying of dry powders

Due to their particle size distribution, some processed products still do not meet application requirements. Fine fractions or oversized particles interfere with further processing or make the final product unsuitable for the targeted application.

Such products require additional “optimization” to meet the desired particle size distribution necessary to improve the product’s characteristics. Customarily products with a particle size range of >100 µm can be classified without difficulty using a screening machine, however, air classifiers are essential for finer particle size distributions that require a more controlled separation.

Typical applications for our fine classifiers are the separation of undesired coarse grains and the distinct reduction of fines (de-dusting).

Different machine designs are available, depending on the desired cut points or application. Machine sizes are available for nearly all ranges of capacity. We carry out the project planning, production and commissioning of individual machines as well as complete classifying plants.
