Agglomerating & Granulating powders with liquids in the Rollo-Mixer®

Agglomerating is the binding together of more than one ingredient into a single, larger particle. The key is to create a liquid droplet that is larger than the particle being sprayed. This combination works well for agglomerating powders into a larger particle size. Over the years, we have worked with manufactures a wide range of spray tips and accessories for spraying liquids and we have done extensive work with our t-jets and air atomizing nozzles. Different spray tips create different droplet sizes and that’s why it is so important to identify the particle size and droplet size you are working with.
There are many forms of granulating powders. Some that involves high energy compaction and some like the Rollo-Mixer® that is low energy granulating. We find that high energy processes will typically create a higher density finished product. Low energy processes often times create a lower density product. Our approach is simply spraying a binder onto a powder, in free-fall, so as to granulate it into a larger particle.
