The wet material is fed through customized feeding systems into the grinding and drying section of the dryer's main body. The grinding rotor disperses the wet material into very fine particles and the fine particles are fluidized in the grinding chamber by temperature-controlled, hot gas coming in from the air heater.

The hot air (or inert gas) can be heated up to 650 °C and as the wet product is dispersed, it is reduced in size in the bottom section of the dryer. The system is kept under a negative pressure by the exhaust fan and the surface area of the product is increased enormously so that water (or other solvents) is evaporated instantaneously.

The dry and fine particles are conveyed with the gas stream to the top section of the dryer where a separator classifies the particles by size. Then the particles pass the classifier at the set cut point and are conveyed with the exhaust air to a powder air separating system like the cyclone, cyclone filter or cyclone scrubbers.

The Micron Dryer flash dryer retains a fluidized bed of product in the drying chamber to ensure a low level of adhesion of wet material on the inside wall of the drying chamber. Moreover, process parameters like classifier speed and outlet temperature can be adapted to control moisture content and particle size of the end product.

  • Ultra fine regular end product - Due to its specially designed dispersion rotor, our flash dryers are able to produce ultra-fine powders in one step from suspensions, slurries, pastes and dough, filter cakes or wet powders.
  • High evaporation capacity - Due to the combination of high ?T with a good dispersion of the wet product in the air, our flash dryers can evaporate large quantities of liquids.
  • Compact design - Compared to other direct drying technologies, the flash dryer requires up to 50% less space.
  • Multi-purpose - Filter cake or slurry, in the same machine. Therefore with the Drymeister-H unlimited mechanical dewatering is possible previous to the final drying stage.
  • Easy access  - Either for cleaning, inspection or maintenance inside the dryer, our flash dryers offers the best accessibility from the market, regardless which size.
  • Various systems available - Open, closed- and recycle system concepts.

Powder Coatings


A powder coating consists of a free-flowing, dry powder that is applied to a surface electrostatically, free from solvents that are used in liquid paint coatings.  Powder coatings are used primarily for metal surfaces, including automotive and marine industries, as well for household appliances, office furniture and other industrial applications.  Particle size defines the film thickness and control of particle size distribution is vital for optimal coating efficiency.  Both large particle and ultra-fine particles pose problems downstream in the electrostatic coating application.

The Mikro-ACM Air Classifying Mill is the standard in the industry.  The ACM efficiently reduces the particles that are produced from the upstream extruder and cooling belt / pre-crusher from ¼” to 3/8” chips to D50 of 35-40 µm and D99 of 90-100 µm.  A downstream Mikro-Classifier CC can be added for those coating applications that specify a minimum ultra-fines level, for example, < 5% < 5 µm.  The Mikro-ACM and Mikro-Classifier CC can also be process coatings for thin film applications that require a D50 in the range of 18-25 µm.

The Mikro-ACM and Mikro-Classifier CC is available in various sizes, from lab/pilot scale to large-scale production.  Other design options include:

•  Special easy to clean designs for quick product change-over

•  Pressure shock resistant (PSR design) for explosion protection

•  Compact and space-saving designs to minimize cleaning time of process ducting, cyclones, etc
