Granular Sulphur

Formed 2–6 mm granules, low friability, deep-sea grade

Granular sulphur is the benchmark form of the world sulphur trade, and the reason is friability rather than chemistry. Formed by wet-drum or fluid-bed granulation into rounded 2–6 mm beads, it is built to survive repeated handling: a properly formed granule stays around 5% or below on the standard friability test, where crushed lump sheds substantially more at every transfer. The chemistry is the familiar recovered-sulphur sheet — 99.8% minimum purity and commonly 99.9%, moisture ≤ 0.5%, ash ≤ 0.05%, acidity as H₂SO₄ ≤ 0.01%, organic carbon ≤ 0.05%, arsenic, selenium and tellurium each ≤ 1 ppm — with bulk density around 1.2–1.3 t/m³ and a bright yellow colour. Size distribution is what you actually contract on: typically 95% within 2–6 mm with the sub-1 mm fines capped, because fines are simultaneously the dust hazard, the flowability problem and tonnage you paid freight on but cannot cleanly discharge.

This is the form to take whenever the sulphur has to cross an ocean, sit in an open stockpile, or move through grab discharge, conveyors and multiple transhipments before it reaches a melter — which describes nearly every Gulf-to-Asia and Gulf-to-Africa acid and DAP/MAP lane. Sulphuric acid plants, phosphate fertilizer producers, mining leach operations, pulp and paper mills and industrial melters all take granular for that reason, and it is the only form most large bulk terminals will accept in volume. Against lump you are paying a forming premium for a bead that arrives intact; against prilled you are buying a tougher, less dusty particle that handles better in bulk while giving up some of the prill's uniformity. CBIL brokers granular sulphur from Saudi, Emirati, Qatari and Kazakh gas-processing and refinery streams against SGS certification of purity, moisture, ash, acidity, carbon, trace metals, screen analysis and friability at load port. Supply is arranged in bulk Handysize, Supramax and Panamax parcels and 1 MT jumbo bags on FOB, CFR and CIF terms — give us your annual tonnage and discharge port and we will structure spot or term supply against it.
