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.

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.

Recording of data and events in written form for later reference. Full documentation is important for all stages of an order. All relevant data is documented and archived, from order entry, production, quality assurance to dispatch. This ensures that the individual processes can be traced back.

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.
