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
For the production of cement or cementitious materials, any type of blast-furnace slag can be used, but the most common is granulated or glassy slag due to its ease in handling and more rapid reactions between the glass and other raw materials 7. As cement is hydrated, calcium silicate hydrates C-S-H and calcium hydroxide C-H form.
BLAST FURNACE SLAG GRANULATION. Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product granulated slag sand used as CO 2 -friendly substitute of clinker in cement production rather than a difficult and costly waste material. Paul Wurth has developed the INBA slag granulation process, incorporating our
Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components
Feb 22, 2019 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.

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 countrys largest captive brick plant Make-Naptune Mahfana with a capacity of 3 lakh fly ash-based products per day by utilising fly ash and slag generated from integrated steel plant.
Slag Granulation is primarily affected by water temperature, water pressure and water ... several trials were conducted at blast furnace slag granulation plant, with varying water temperature and flow rates. The granulated slag samples ... function. Normally, a vertical shaft impactor is used for crushing stones. In a shaft
Jan 01, 2018 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.
May 21, 2020 One is using of a high-pressure water jet, which blends with the slag or impurities then we send the mixture to the granulation plan, secondly if it is unable to granulate in the granulation plant then we make a separate area where we dumped the slag.

Function Of Slag Granulation Plant. The process of slag granulation involves pouring the molten slag through a high pressure water spray in a granulation head located in close proximity to the blast furnace Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place
The invention relates to the granulation of molten slag directly from metallurgical furnaces. Known installation granulated slag containing slag chute, which consistently are hydrogenerator, a hopper - sump with grate and overflow device and coupled with well installed the airlift, connected in turn with the dehydrator carousel with feeding hopper and the discharge hopper,
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. Kingtech uses water quench process to release heat stress. The product size is ranged 2-3mm, steel granules and slag are separated. Granulated steel slag Air cooled steel slag
The term granulation involves rapidly cooling the liquid-hot slag under the pressur-ized cold water and obtaining the slag in the form of irregular granules. The quality of granules depends on the chemical composi-tion of slag, slag temperature before spillage, rate of slag spillage, pressure and the amount of cooling water 4.
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.
