Tenova Pyromet has vast experience in the design and construction of wet granulation plants. The wet slag granulation process involves pumping water into the slag cold runner via a blower box to quench the molten slag. The inhouse designs have been proven in numerous applications and have shown to be both robust and reliable.
Wet granulation of titania slag Description and operation of the wet granulation plant Wet granulation of titania slag was carried out at the research and development facilities of Exxaro in Pretoria. Ilmenite was smelted in the MW DC furnace at this facility. The typical titania slag tap mass was approximately one ton.

JSW Steel has set up a unique BOF slag granulation plant, producing slag with lower free lime content and is vigorously pursuing with BIS. JSPL has set up country''s largest captive brick plant (MakeNaptune Mahfana) with a capacity of 3 lakh fly ashbased products per day by utilising fly ash and slag generated from integrated steel plant.
Slag is the glasslike byproduct left over after a desired metal has been separated (, smelted) from its raw is usually a mixture of metal oxides and silicon, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
The envisaged annual capacity of the plant is granulation of 530,000 tons of liquid slag. The plant for granulation of blast furnace slag is an addition made within the scope of the modernization project for the existing Blast Furnace, and is also part of the technological entity for production of crude iron.
CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed to a countercurrent moving packed bed heat exchanger, where they are further cooled and finally discharged at close to ambient temperature.
