Fig.3: Slag Granulation Plant Process The process of slag granulation involves pouring of molten slag through a high pressure water spray in a granulation head, which is located very close proximity to the blast furnace. Granulation process is controlled by quenching of the slag in cold water. This process does
Granulated Blast Furnace Slag an overview . A potential problem is moisture, which occurs in blast furnace slag during the granulation process achieved in a oratory ball mill, was not as high as that commonly occurring for commercially availe OPC clinker Dust generation in specific sections of cement plants (crushers, raw mill, coal mill, kiln, …
Today, blast furnace slag is a value-added product for the cement industry, using granulated slag sand as a CO 2-friendly substitute for clinker in cement production. Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA ® dewatering drum. With about 300 references, it is the most popular and ...
Following different test series, where the slag quality and suitability for cement production was proven, Paul Wurth built a full scale dry slag granulation pilot plant at Rogesa's blast furnace No 4.
