Bateman Engineering provides a comprehensive rangeof slag-granulation technologies. The equipment

offered primarily uses water as the granulation medium,as the Bateman Engineering process has been developed

and proven to lose far less water by evaporation thanother commercially available processes.

Particles in excess of 1 mm in size are generallyproduced, but this depends on the process applied.

The range of slag-granulation productssupplied includes:

I Bateman-Stillwater Granulator

I Bateman Launder GranulatorI High-tonnage slag granulators

Bateman Engineering has supplied many slag-granulation

systems, often on repeat business from the same clients.

The reliability and accuracy of these installations have been

demonstrated and references can be supplied on request.

These slag-granulation systems are an integral part of the

range of processes available from Bateman Engineering for the

solidification of liquid metals and slags to produce particles

ranging from the smallest (atomisation) through granulation to

larger lumps (blobulation) to ingots (pig-casting).

I Bateman-Stillwater Granulator

The Bateman-Stillwater Granulator with a semi-closed tank is

used mainly in the non-ferrous industry. Granules are formed

during the molten metals freefall into a waterjet and quenched in

a cyclonic water bath.

I Compact and highly economical closed-circuit system for

flows up to 2.5 t/min

I Granulation slurry discharge via pumping or gravity to

de-watering system

I Minimal steam generation

I Semi-closed-tank operation permits installation inside

smelter buildings

I Bateman LaunderGranulator

This launder slag-granulation process uses a double stream ofwater, the upper for dispersing the liquid metal during freefall

and the lower to quench the granules. Granulation is achieved in

the waterjets before the granules reach the bottom of the sloping

launder from where they are discharged to a de-watering system.

I Continual or batch flows of up to 3 t/min

I The launder normally discharges into a de-watering pond

I Pre-cast concrete or steel launders with hardwearing liners

are widely used

I Minimal steam generation

I High-tonnage slag granulators

These are used in the production of blast-furnace and Corex

slag, LD (Linz-Donawitz) converter slag and slags in the non-

ferrous industry. More than 50 are in operation worldwide.

I Any flow rate, but flows usually exceed 3 t/min

I The unique granulation heads are extremely safe and

produce a high-quality product

I Bateman Granulators

Bateman Engineerings open-tank slag granulators produce the

granules at the point where the freefalling molten slag and the

waterjet meet at the surface of the quenching-pond surface.

I Slag flows in the order of 2 t/min
