At our Innovation Lab, we develop entirely new processes when the desired results cannot be achieved with standard solutions. Our customers can practically watch over our shoulder and participate in the process to the extent they choose. The results are then put to the test in the adjacent Technical Centre. Sometimes this opens up whole new business areas for our customers. Getting more than they bargained for – that’s one more thing our customers appreciate.

At our Technical Centre, which has proven its worth over many years, even the smallest quantities bring you great benefits. With an area of over 1,000 square metres, we offer the perfect facilities to verify how the raw materials will actually behave in the intended processes and finishing steps. In addition, we run scalable test series to generate reliable data for calculating costs. The process in three steps: 1. Pilot trial: testing on the smallest scale 2. Scale up trial: testing on the high-performance universal mill, with close support from our experts 3. Large-scale production: testing on the large plant for production on an industrial scale

Process of grinding and ultra fine grinding during which compressed air is blown into the grinder under high pressure through nozzles, thereby swirling and crushing the particles. Examples of our services: 1. PA12: d50 = ca. 5 µm; 2. PEEK: d50 = ca. 8 µm; 3. PPS: d50 = ca. 12 µm; 4. PA11: d50 = ca. 8 µm Let us know what you would like us to do for you!

Method for determining the grain size; air jet sieve, vibrating sieve, but also used in a production system for separating the coarse component of a powder so as to obtain the desired grain size distribution. Using acceleration to separate particles of different weights and therefore mostly different sizes.

DG Mixing process which under the application of high speeds injects enough energy into a powder quantity to create a stable compound from different types of powders and grain particles. Used, for example, for coating surfaces of one type of particle with other particles.

Fine grinding of dry products is a core competence of the Dressler Group. An extensive range of machine and system programs are available for this, offering the right solution for almost all applications. Finenesses from 1 μm (d97) and into the millimetre range can be reproduced here.

DG Grinding processes with simultaneous cooling of the raw material to temperatures far below ambient temperature (e.g. minus 30°C); usually done with the help of liquid nitrogen, which has a temperature of around minus 196°C.

We developed a special process for making fine powder systems and composites from low-viscosity melts. With the patented cryo-spraying process CSP, it has become possible to produce highly sensitive products directly from a hot melt to form a solid powder without after-cooling. The entire spraying process is overlaid with nitrogen and also protects very critical substances against oxidation and thermal stress.
