SULPHUR DRUM FORMER

Operation guideline and operationconditions

(1) Features of material

Name of product: Sulphur

Meltingpoint:~115-120℃

Feed Temp.:~125-135℃(higher temperature will cause bigger granules size)

(2) Operation data

Production capacity:~20-25MT/hours per set

Main dimension of particle: Φ2-8 (round)

Granulation discharging temperature: low than 60℃

(3) Operation mode continuous or intermittence

(4) A brief introduction to technological process

The liquid sulphur will be supplied from sulphur tanks (by Contractor) by pump through sulphur re-melt tank and basket filter and via a jacketed

pipeline directly to the drum granulation system.

The liquid sulphur will be spray into drum through sprayer in the drum, cooled and freeze in the drum with drum rotation, the round solid sulphur will form. Round solid sulphur will flow out through drum, then the sulphur will feed into storage system through collect conveyor and bucket lifter and feed into silo (by contractor).
