Granulation operations at Bepex are focused on increasing the overall particle size of your material, either through force/pressure or through agitation with a liquid binder. In either case, the result is a larger, denser, and often times stronger granule. In high-pressure granulation, we are often able to compress fine powders or granules without liquid binder. This pressed sheet of material is then milled in series of grinding steps to produce a strong and dense granule, often with low dispersion characteristics. In wet agglomeration or particle growth, the fine powder or granular material is agitated with one or more liquid binders which aid in cohesion. The resulting product is either a pellet, sphere, or irregular shaped granule which generally has medium to high dispersion characteristics. Wet agglomeration often requires post-drying or curing of the wet granules, which we typically carry out with our Fluid Bed dryer.
Granulating
DRY GRANULATION
- Utilizes high-pressure Roll Compactor to join fine particles into a densified sheet of material
- Compacted material moves through a series of grinding mills producing a specified size range for maximum on-size product
WET GRANULATION
- Utilizes liquid binder addition to fine solids, effectively growing particles
- Typically requires a curing or drying step following granulation
- Resultant granules are dust-free with lower strength and quicker dissolution than in dry granulation
GRANULATION PRODUCTS
Granulation products by Bepex can be divided into two primary categories; wet or dry (i.e. high pressure) granulation. In dry granulation, our Roll Compactor serves as the primary technology, able to handle a range of feed materials, including low-density or highly aerated fines. In wet agglomeration, a liquid binder is added to grow particles along with mechanical agitation. All of our granulation systems are available for testing in our Process Development Center, allowing us to find the best solution to match your process needs while simulating an entire granulation system.
