Blast Furnace Slag Pulverizing Mill

Blast furnace

This blast furnace slag floats on top of the liquid hot metal and contains the fluxes and the gangue of the iron ore. The slag is tapped, granulated by means of a highpressure water spray, dewatered in rotating drum filters and transported for use in the construction industry. During the production of liquid hot metal, large quantities of gas are also generated in the blast furnace ...

How to Make Cement From BlastFurnace Slag

· The slag sand being already fairly small, a twocompartment mill is sufficient for slag cement: It is essential that slag cement be ground exceedingly fine; the finished product should not contain more than 3% oversize on 100 mesh per linear inch sieve, nor more than 15 % on a 200mesh sieve. Limeburning, slaking, and screening, as usually carried out, are slow, tedious, and expensive. .
