Synthetic aggregates are produced either from blast furnace slag, steel slag, or from wet bottom boiler slag. Blast furnace or steel slag is produced as a by-product of iron or steel production.
Industrial wastes, such as blast furnace slag, fly ash and silica fumes are being used as supplementary cement materials. ... It is found that as the age of aggregate crusher screen increases from 0-2 years, 2-4 years, 4-6 years and …
The current water quenching process is to use water with a pressure of 1.5 ~ 2.5 kgf / cm2 and a dosage of 5 ~ 10 times the amount of slag to quench in front of the furnace. Granulated slag can also be used as thermal …
Slag, a byproduct of metal smelting processes, is produced in large quantities by steel mills, foundries, and other metalworking industries. While once considered waste, slag is now recognized as a valuable resource due to its potential applications in construction, road building, and other industries. Stationary recycling crusher plants for slag play a crucial role …
This paper presents the results of a research project, which analyzed the viability of reusing thermal power plant slag as a substitute for natural aggregate in the manufacture of hot mix asphalt ...
When smelting each ton of pig iron, approximately 500 kg of blast-furnace slag is formed and requires recycling. Air-cooled blast-furnace slag can be used for the manufacture of slag aggregate for ...
About 20% of slag is dumped into the slag cooling pit and crushed with mechanical crushing systems after cooling. The crushed slag is passed through magnetic separators to separate the metal. The metals are collected as recycled metal and the remaining slag is an iron free material suitable for cement plant admixture with maximum size of 4.5mm.
