Some Fundamental Aspects of the Dry Slag GranulationProcess . Sharif Jahanshahi*, Yuhua Pan and Dongsheng Xie . CSIRO Minerals Down Under National Research Flagship, Clayton, Victoria, 3168, Australia . Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the
2019-05-09· Primetals Technologies has developed a new innovative blast furnace dry slag granulation process with heat recovery at the voestalpine pilot plant in
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 and finally discharged at close to ambient temperature.
Fig.9- Dry Slag Granulation Plant. Intelligent automation for ironmaking. The blast furnace process control system in combination with the blast furnace optimization system creates the next level in intelligent blast furnace automation. The optimal interaction between sophisticated models and the expert system provides extended assistance to plant operators and minimizes the risk of human
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 in-house designs have been proven in numerous applications and have shown to be both robust and reliable.
A slag granulation plant basically consists of granulation, dewatering, and storage sections. Different granulation processes could be applied in granulation section. The liquid slag is either fed into a slag pot or it is directly fed via a runner to a granulation plant in order to produce conventional water GBFS. From the runner, the liquid
Dry Slag Granulation. Steelmaking slags are typically dumped to ground and used as low-value road aggregate. Hatch’s dry slag granulation process uses air to directly granulate slag. The dry slag granulation advantages include improved safety, reduced noise and pollution and ability to access higher value-added slag markets. Custom Robotics

Slag Granulation Plant Process Sdm China; About Us. SHANGHAI GME MINERALS CO., LTD. is a hi-tech, engineering group. We are specialized in the research, development, and production of industrial crushing, powder grinding, mineral processing equipments and other related devices.
Based on the assumptions made in carrying out the evaluation, the operating cost of the dry granulation process was estimated to be A$4.80/t slag for a 300,000 t/y slag plant, with a capital cost
second granulation tank, one granulation unit can handle the slag of two tap holes. `Continuous filtering and evacuation of dewatered slag sand up to its storage facility without inter-ruptions for purging. ` High reliability. `Measurement of slag flow, due to the design of the drum and the dewatering process.
To cool and fragment the slag a granulation process can be applied in which molten slag is subjected to jet streams of water or air under pressure. Alternatively, in the pelletization process the liquid slag is partially cooled with water and subsequently projected into the air by a rotating drum.
slag dump is constructed of which the capital and running costs are way in excess of those of a slag granulation plant. Processing of such slag-dumps is very labour intensive and costly, where crushing and screening plants are utilised to reduce the slag-dumps by either
slag granulation process. Wet granulation of blast furnace slag has been practised for many years. Various systems are in use and all are based on the quenching of molten slag with water. The original process was the OCP granulation system (gravel layer filtering plant) the starting point for further development of the granulation process
BOF Slag Granulation Plant Steel slag from BOF (Basic Oxygen Furnace) steelmaking process was cooled by nature in the past. This material will swell and crack if directly used for road paving.
