Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of slag into a saleable

flexible; and the compact sub-plant can be applied to any furnace configuration. Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics. 4. TYPES OF SLAG After granulation of slag based on that appearance it was majorly divided into four groups. a.

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 counter-current moving packed bed heat exchanger, where they are further cooled …

Granulated slag slurry is pumped to an adjacent dewatering plant with 2 INBA drum dewatering systems. Each furnace has a hot blast stove plant with 3 external …

The Manufacturing Process Manufacturing Skyway Slag Cement requires two basic processes: granulation and grinding. Blast-furnace slag is produced in a blast furnace during the reduction of iron ore to iron. It consists of non-metallic minerals, which are tapped slag from the blast furnace while molten. By processing blast furnace slag into Skyway …

Snapshots of centrifugal granulation of molten blast furnace slag by (a) rotary disc atomizer [72], (b) ... In the industrial-scale CGATER plant, the granulator diameter was increased to 5 m to process the molten BFS at a rate of 300–500 kg/min. The industrial CGATER tests are highly desirable while no latest information is available yet.

The slag granulation system is based on the INBA® slag granulation process, incorporating our proprietary dynamic INBA® dewatering drum. ... Seamless integration and efficient use of existing steelmaking and downstream plants; Production of blast furnace equivalent slag as a by-product for utilization in the cement industry as a clinker ...

Then final products of the blast furnace is molten pig iron, slag and top gas. The main product of the blast furnace is molten pig iron and by products are slag and top gas. During the process of formation of molten metal, CaO is chemically reacted with SiO 2 and from the slag, this slag is send to slag granulation plant.

Water is used for cooling the blast furnace, slag granulation treatment, and top gas scrubbing, and is lost by evaporation in electricity cogeneration. ... Brazil: one plant in the state of Minas Gerais. Included: coke, coal, iron ore (lump, pellet, sinter), limestone, electricity, oxygen, nitrogen, compressed air, and closed-loop recycling ...
