Proper equipment selection for granulation enables better product quality alongside operational efficiency gains and standard compliance measures.
FAQs
What is the difference between wet and dry granulation?
The process of wet granulation combines powders with a liquid solution followed by granule formation and drying. Dry granulation differs from moist granulation by compressing powders into granules without adding liquids when processing sensitive components.
Which granulator is best for heat-sensitive materials?
Gentle granulation occurs through fluid bed granulators as well as spray drying granulators due to their capacity to process heat sensitive materials.
Can one granulator handle multiple materials?
Oscillating and swing granulators are two types of equipment which can process multiple substances. Selecting the best transformer oil depends on material properties plus processing control but you need to consider other factors too.
