CRYOGENIC GRINDING WITH DEMINO®. IT’S SO COOL. Our impact whirl mill DemiNo® grinds steep particle size distributions that have no equal. Curves so tight that even dust removal is no longer needed: only two processing steps are necessary – first micronisation, then classification. With special cryo equipment and a rotor especially developed for cryogenic processing, DemiNo® […]

Micronisation   NOLL toll processing uses a variety of machinery to process bulk materials up to Mohs hardness 10 to your required fineness. We are especially equipped for the iron-free and contamination-free processing of products down to <2 μm as well as for smallest batches of 5 kg to be processed on our laboratory machines. Highly […]

Our dynamic air classifiers solve even the most difficult separation tasks between 3 to 300 m, with sharp top cut and close particle size distributions. We remove the coarse particles from special effect pigments or the fines from metals and ceramic pigments. High-purity materials are separated using polymer-based or ceramic parts and machinery lining. Feed […]

Standard mixing and blending tasks are performed through a range of batch and continuous mixers. We reach highly homogeneous raw material mixtures through the use of energy-efficient impact whirl mills. Our opposed jet mills can also solve extremely difficult tasks, including the processing of abrasive materials and the use of additives for surface coatings. Feed size […]

To obtain a pure product which reduces wear and tear on industrial machinery like paper rollers or plastic extruders: selective grinding is the perfect solution. It is also an effective method to purify contaminated powders in order to regain the valuable materials they contain. Using NOLL’s innovative classifying procedures, materials of different densities can be separated […]

Optimized in three decades of NOLL’s practical experience: processing in an inert protective medium. Under nitrogen or – for special materials and refinement – under argon. We’ve set highest safety standards to prevent the risk of inflammation, explosion and fire. Depending on product and processing technique, the oxygen range in the protective atmosphere is maximally […]

GREATER SURFACE AREA… Milling while creating larger surfaces and new molecular surface structures: NOLL fine particle technology achieves smallest, uniform particles in the micron and nano range – and e.g. through surface rounding an increase in fines weight or better flow characteristics of a product. Minerals, clay or synthetic gypsum (<4 μm) designed for construction […]

The coating of particles is a classic refinement method. It increases the powder’s inherent value as well as that of the manufactured end product. NOLL offers specific expertise in three basic  coating procedures and is a recognized partner for custom-coating solutions: through our creative development and engineering, many innovative product ideas have become reality. Depending […]

THREE GOALS, ONE GO. Exact reproduction of the defined maximum particle size, while removing finest particles and enhancing flow characteristics or fines weight – according to your product requirements: NOLL  engineering has significantly reduced processing steps, even for extremely hard materials. We make combination processing work: with our individual concepts, multifunctional systems and time-saving online […]
