Drying plays a crucial role in agglomeration, and can be utilized in both pre- and post-agglomeration processing.
Many materials must retain a certain moisture level in order for agglomeration to occur. Thus rotary dryers can be implemented to reduce the feedstock’s moisture prior to agglomeration, preparing it for optimal pellet formation. Pre-drying can also improve subsequent processing steps by reducing the likelihood of issues such as clumping, a common problem with hygroscopic materials.
As a post-agglomeration step, drying helps refine the pelletized end-product by reducing moisture to the optimal level. Meeting a certain percentage of moisture ensures the pellets are strong enough to withstand handling and transportation, and yet still break down as needed in their intended application. Drying after agglomeration also polishes the pellets as they tumble inside the rotating drum, ultimately creating a round and smooth product.
