Abstract
A portable apparatus for producing sulphur granules includes a granulator with a rotatable drum having distinct zones for seed generation and product growth. The seed generation zone has an intense water spray pattern for each sulphur spray nozzle with intersecting water sprays to solidify molten sulphur and create seeds. The growth zone has a moderate, non-intersecting water spray pattern to allow sulphur nozzles to coat and grow a curtain of seeds into granules. The granulator's exhaust air is filtered either by a heated cyclone separator to recapture residual sulphur particles and moisture before venting, and/or by a granular air filter which uses the produced granules to filter the granulator's exhaust air. A two piece collar enhances maintenance of the granulator's drive system.
