Ceramics, Fine Ceramics, Hard Metal - The spray dryer design and operating
conditions are selected to meet each ceramic product specification.
PRODUCT GROUP EXAMPLES:
- Aluminium Oxides
- Electroporcelain
- Ferrites
- Silicium Oxides
- Titanates
- Carbides
Within this industry we offer a broad range of technical solutions and
tailor-made applications to meet the specified product property requirements.
For both traditional and advanced high-tech ceramics we have supplied a
number of plants with spray dryers in open and closed concept.
The
spray dryer design and operating conditions are selected to meet each ceramic
product specification of moisture content, bulk density, particle size
distribution, etc. to obtain a reproducible free-flowing granulate for
production of ceramic press-body of high uniform quality in one single
operation.
The transformation of a water-based ceramic
slip specified with high solids content, binder and lubricant into a controlled
droplet distribution using rotary wheel or nozzle atomisation is mainly
performed in open concepts with ambient air as the once-through process gas.
Closed cycle dryers with inert gas as process gas are used to prevent
oxidation degradation or to operate safely with organic solvent-based ceramics
(tungsten carbides).The flammable solvent evaporated from the feed formulation
is fully recovered as liquid in a wet scrubber-condenser system.
