Pelletization an overview ScienceDirect Topics

2012-1-1  Pelletizing differs from other agglomeration techniques in that the powdered ore is first formed into a “green” pellet or ball, which is then dried and hardened in a separate step, usually by heating. Green pellets are made by combining moist ore with a binder and rolling it into balls using either a pelletizing disk or a pelletizing drum.

A REVIEW OF PELLETS AND PELLETIZATION PROCESS A

Pelletization is an agglomeration process that converts fine powders or granules of bulk drugs and excipients into small, free flowing semi-spherical units. Pellets, being multiparticulate systems, are widely used due to the technological as well as therapeutic advantages over single-unit dosage forms. The present review focus on advantages

US4081500A Sulphur pelletization process Google Patents

Sulphur pellets are produced by spraying molten sulphur from a vortex nozzle in the form of a downwardly diverging conical sheet or jet. The sulphur impacts on the surface of cooling water in a tank. The diverging nature of the jet and the resulting turbulent swirling action promotes the formation of pellets. Control of the size, surface texture, porosity and density of the pellets can be
