Powder agglomeration processes of bulk materials
Granulation is a process that is well-known and widely used in various industries. This is primarily used when bulk material in the form of a fine powder is considered difficult to treat and process [1].The process is designed to convert fine powders into granular materials with controlled physical properties, i.e. a specific shape (granule size) and a specific bulk density.
