Cryo-Spraying System (DG Patent)

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.

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.
