PROCESS FOR PRODUCING CEMENT CLINKER CONTAINING BLAST FURNACE SLAG |
摘要 |
<p>Undried blast furnace slag, for example, granulated blast furnace slag having a water content of 3 to 20, generally 5 to 15%, by weight, is introduced to hot clinker in a cooler downstream of a cement kiln; the water is volatilized or evaporated in the cooler to provide a cement clinker having an effective content of dried blast furnace slag free of water; this permits use of blast furnace slag in a blended cement without the need for separate special steps for drying the slag.</p> |
