Estimating the term…
A method and apparatus are provided for generating seed particles. In one technique, a spray of water droplets is discharged to intersect a spray of liquid sulphur droplets to effect contact between some of the sulphur droplets and water droplets. The cooling sulphur droplets form seed particles. In another technique, water is sprayed into dispersed sulphur granules moving through a processing region. Subsequently, as the water is evaporating from the granules, liquid sulphur is sprayed onto the granules. Some of the liquid sulphur droplets impinge upon the water film-coated granules and solidify to form new seed particles which become detached from the granules. In another technique, a stream of liquid sulphur is discharged under pressure into a receiving region. A plurality of jets of atomizing fluid are injected into the stream to form a spreading spray of liquid sulphur droplets which solidify into seed particles.
A method of continuously generating sulphur seed particles to be used in a process of spraying said seed particles with liquid sulphur to form sulphur granules larger than said seed particles, said method comprising:
