RS1500™ Sulphur Granulator
The RS1500™ granulation process produces formed sulphur that meets or exceeds SUDIC specifications for premium product, is fully automated and designed to run under a variety of ambient conditions.
Seed particles of solid sulphur are generated by freezing sprays of liquid sulphur in a water bath at controlled pressures to form a desired size range. The particles are then augured into a slowly rotating drum with flights attached to its inner surface. The flights create curtains of particles inside the drum as they are gently moved towards the discharge end of the drum.
The seed particles are progressively enlarged to product size by coating the curtains of particles with sulphur spray from a bank of nozzles running the length of the drum. The temperature in the drum is moderated by the evaporation of water from the spray nozzles. Sulphur granules of product quality are discharged to a belt conveyor for transport to storage and/or further handling.
A fan is used to draw a stream of air through the drum to sweep out water vapour and fugitive dust inside the drum. The dust is scrubbed out of the exhaust stream using a venturi cyclone type wet scrubber before the process air stream is released to the atmosphere.
The underflow from the wet scrubber cyclone is pumped to the same settling/dewatering tank that is used to generate the seed particles. Here the fines settle out and are augured up along with the sulphur particles generated by the seed generator spray.
The CPU control cabinet has a dual HMI allowing the operator to see the process overview, operating control status and detailed real time trend analysis. The systems are auto correcting within the set process parameters and will automatically shut down for an out of control situation.
The forming unit start up and shut down are sequenced with a single click of a mouse. Data collection, reporting and filing is customized per the customer’s requirements.
