Method and system for pelletizing sulfur
Relatively uniform spherical shaped solid pellets (prills) may be created by passing molten sulfur through a nested strainer to remove particles that would otherwise become trapped in the system, a drip tray with a heating channel attached on its underside, an injection conduit for delivery of a cooled zone of water to create solid prills, and thereafter moving the prills through a stationary curved screen to remove most of the excess water and a vibrating screen.
