Powders can be processed to suitable morphologies and sizes by different methods. Mechanical sizing by crushing and sieving into the wanted particle size fraction, freeze granulation, spray granulation, agglomeration, spray coating and spray drying are available techniques at different throughputs resulting in significantly different powder morphologies and particle size fractions. Equipment for calcination and heat treatment in different atmospheres are available.
A major part of the infrastructure is related to powder processing.
The techniques available for powder tailoring are spray drying, spray coating, spray granulation and agglomeration. The different equipment enables the production of different materials, and different batch sizes from gram scale to several kilograms per day. The equipment selected is based on processes which are easy to scale up to industrial scale. The equipment for processing of powders is the following:

GEA Mobile Minor |
spray drying of materials (up to 2 kg per hour in air). |
Spray dryer |
ProCept module |
Flexible spray dryer where the process can be easier followed using glass equipment. Typical throughput is 100 g per hour. This equipment has been risk assessed and procedures have been developed for safe operation with solvent based systems (e.g. ethanol and isopropanol) |
Spray Dryer |
Buchi Mini B-290 |
Smallest spray dryer resulting in lower throughput and easier operation |
The equipment is very well suited for developing materials with different morphologies by different processes which are possible to scale up. The equipment is run and monitored by skilled technicians and scientists. The choice of the right experiment/experimental conditions for a specific test can also be established through discussion with our experts.
The above-mentioned powder production can be performed in a single lab. Prior to processing, it is possible to crush down materials and sieve to selected size ranges if necessary. A wide range of characterization tools are available on site in different laboratories.
