Granulated Blast Furnace Slag (GBFS) is a byproduct of the steel industry which when ground and blended with cement improves the strength, chemical resistance, and durability of the resultant concrete. Ground Granulated Blast Furnace Slag (GGBFS) is a cementitious material and can be substituted for cement on a 1:1 basis.
Jun 16, 2019· Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron.
Pfeiffer products for the preparation of cement and granulated blast-furnace slag . ... Grinding of cement and/or granulated blast-furnace slag – Material separation in the filter. The cement components are ground, dried, and classified in the Pfeiffer vertical roller mill. Moist feed materials can be fed to the mill separately from warm and ...
The grinding of clinker and cement and of granulated blast furnace slag and slag in vertical air-swept grinding mills dates back to Ernst Curt Loesche's invention. In 1927, he applied for a patent for the world's first spring-loaded air-swept mill – the beginning of the triumph that is Loesche vertical roller mills.
Grinding of blast furnace slag is conventionally performed in a tube mill with a dryer, which is a power-intensive option. Energy efficiency of this process can be improved by grinding the blast furnca slag using vertical roller mills (VRM) or by using a VRM as a pre-grinding step for the tube mills.
Ground granulated blast furnace slag (GGBS) ... GGBS is produced by grinding Granulated Blastfurnace Slag to a controlled fineness. There are a number of different methods of grinding granulated blastfurnace slag. Traditionally, standard ball mills have been used, but since the early 2000s the use of roller presses and vertical mills has ...
Ground granulated blast furnace slag (GGBFS) has been used for many years as a supplementary cementitious material in Portland cement concrete, either as a mineral admixture or as a component of blended cement. The use of GGBFS in Portland cement is governed by AASHTO M302. (1) Three types of ground granulated slag cements are typically ...

Overview. Vertical Slag Mill is the equipment to grind Ground Granulated Blast furnace Slag into small particles. In China, quality slag (fineness:4200-4500cm2/g) produced by vertical roller mills are being used to substitute clinker in conventional cement manufacturing as well as to partially replace OPC for ready-mixed concrete production, for which the percentage of GGBS usage is typically ...
cementitious blend of Portland cement (OPC), ground granulated slag (GGS) and flyash (FA) has been used in N.S. W. since 1966. This paper presents an assessment of the properties of GGS, from the Port Kembla works, in cement blends. Slag from one blast furnace at Port Kembla may be granulated either by water or by air (pelletized slag - Slaglite).
These slags are ground to high fineness to generate good strength properties, but the intergrinding of clinker and granulated blast furnace slag requires the unfavourable grinding of the clinker ...
Pfeiffer's compact mill solution is perfectly suited for annual production rates of up to 550,000 tons of cement, slag, and granulated blast-furnace slag. Find out more! Modular grinding plant | Mill .
Apr 10, 2013· Although blast furnace slag contains a small component of elemental sulfur (1 % to 2 %), the leachate tends to be slightly alkaline and does not present a corrosion risk to steels in pilings or to the reinforcement steels embedded in concrete structures made with blast furnace slag cement .
Blended cements produced by intergrinding of the constituent materials use granulated blast-furnace slag, the glassy granular material that results in slag cement when ground to a fine powder. Slag granules are added to the grinding mill along with portland cement clinker and .
