What is a Slag Crusher Machine and How Does it Work?
Slag is a by-product of the steel-making process that is typically formed when iron ore is melted along with other minerals and impurities in a blast furnace. This molten slag is then cooled rapidly, resulting in a glass-like substance that can be ground into a fine powder. Slag has a variety of uses, such as in the construction …See more on crushing-machine
