Powder layering pelletization particle agglomeration

They are harder compared with pellets produced by powder layering. Their appearance is similar to pellets obtained by fluidized-bed granulation using the so-called rotating fluidized bed. " Owing to the fact that ideally round pellets are desired, several attempts were made to quantify their roundness. " The spherical agglomeration is a completely different method that is employed to develop pellets that are round and uniform in size. In this, particles are agglomerated in suspension. ...
