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 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
A method of controlling a supply of coolant gas to a dry slag granulation system, the system comprising: a rotary atomising granulator; a slag receptacle, for supporting a slag bed which is formed thereon when slag particles are expelled from the granulator, the slag receptacle comprising a plurality of cooling inlets for cooling respective zones of the slag bed; and at least one height ...
A Definitive Guide to Fluid Bed Granulation Process (Updated) Fluid bed granulation is a popular material processing technique in many industries. Quite a number of industries use it as a means of transforming the dusty powder into desirable granules. But before I explore the fluid bed granulation process, let''s review granulation process in ...
them, slag granulation process by a centrifugal force, which is also called DCG process, has proved its advantages due to its simpleness, controllability, less energy consumption and more sensible heat recovery in the past –9) In this Modeling on Dry Centrifugal Granulation Process of Molten Blast Furnace Slag
Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between and mm depending on their subsequent use.

Some Fundamental Aspects of the Dry Slag GranulationProcess . Sharif Janshi*, 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
Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Heat is recovered from the slag in the following ways. As the spray of slag particles moves outwards from the atomizer, heat is lost by radiation to the vessel and by convection to the air moving through ...

The granulation of molten material, blast furnace slag for example, is accomplished by wetting the slag with a stream of water and thereafter transporting the thus formed granules away from the point of granulation with the water stream. Water consumption is minimized and average grain size increased by employing a multilayer water stream defined by currents having different temperatures and ...
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, and well air pump ...
