To facilitate handling, we offer compaction of powder materials to granulates.
The benefits of granulates include reduced exposure of dust in the application, in a usually higher, more uniform bulk density, or in improved mixability with other coarse-grained components such as plastic granules. Granulation frequently also achieves improved storage stability and dosing capability.
Numerous materials can be granulated in the roller compactor without adding binding agents, which might not be compatible with the application of the products.
The compacted product is transformed to the desired size in a suitable crushing unit and filtered to separate it from the fine component. Different grain sizes can be set according to the purpose by selecting the parameters.
Gentle compaction is possible in a vacuum-pressure rolling mill. The air trapped in the powder materials is extracted by applying low pressure to a porous compactor roller. This type of compaction can be applied as an independent process or can precede a subsequent processing step.
