1985 Mills for grinding cement and granulated blast furnace slag were installed in Asia under licence from Loesche. 1994 The 2+2 technology, which was specially developed for grinding clinker and granulated blast furnace slag, was used for the first time in an LM 46.2+2 for cement grinding in the Pu Shin mill works of Lucky Cement, Taiwan.
It is necessary to pass the granulated slag under a strong magnet in order to remove any particles of metallic iron. Blast-furnace slag is used in making-four classes of cement— Puzzolan, or ordinary slag cement, usually simply called slag cement. Slag Portland cement, which may be a true Portland cement.
Accordingly, the present invention provides an improved process for the production of Portland slag cement using granulated blast furnace slag, which comprises: (viii) forming of cement clinker by known process, (ix) ball-milling of cement clinker for a period ranging between 30-60 minutes in dry condition, (x) reducing size of granulated blast furnace slag by any process to obtain the size in ...
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Feb 20, 2013· Grinding of cement clinker and granulated blast furnace slag in roller grinding mills is a technology introduced by Loesche. The breakthrough in grinding this type of material on the vertical ...
Granulated blast furnace slag and vitrified pelletized blast furnace slag are also used in the manufacture of blended hydraulic cements (AASHTO M240). (3) When used in blended cements, granulated blast furnace slag or vitrified pelletized slag are milled to a fine particle size in accordance with AASHTO M302 requirements.
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g. (8)
The ground granulated blast furnace slag (GGBFS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree ...
This material is produced by grinding dried Granulated Slag in a closed circuit milling system to a surface area of ~380m2/kg. This Granulated Slag is the same material used to produce Blastfurnace cement. The quality control of Ground Granulated Blastfurnace Slag manufacture is in five stages:

In the year 1995 Kolkata-based Shree Cement Ltd. was the first Indian ... for the 100th Pfeiffer vertical roller mill in India to be set up at Bihar Grinding Unit. ... simultaneously dry and classify the material in one and the same machine, but also to process very moist feed materials like for instance granulated blast-furnace slag.
Ground granulated blast furnace slag to the grinding aids and enhanced roll method, the method using from about 0.002 to 0.2% (by weight) of polyacrylic acid or an alkali metal salt and from about 4% (by weight) in water treated with a combination of rollers blast furnace slag feed press.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Portland blast-furnace slag cement: A blended cement consisting of an intimately interground mixture of portland cement clink- er and granulated blast-furnace slag or an inti- mate and uniform blend of portland cement and fine granulated blast-furnace slag in which the amount of the slag constituent is within specified limits. Hydraulic cement:
Features of GGBS/GGBFS/GBFS Ground Granulated Blast Furnace Slag Powder grinding mill : 1.High Efficiency . Under the same finished final size and the same motor power, the capacity of GGBS/GGBFS/GBFS Ground Granulated Blast Furnace Slag Powder grinding mill is twice as much as jet mill, mixing grinder and ball mill, and energy consumption decreased 30%.
Skyway Cement receives granulated slag from a US steel manufacturer in Gary, Indiana. In the blast furnace at the steel works, slag is produced when the mineral components of th e metal refining process separate from and float on the molten iron. The iron is drawn off to be further refined into steel and the slag is drawn off to be granulated.
In this study, wet grinding was adopted to promote the activity of GGBS and the dissolution of gypsum. Wet grinded granulated blast-furnace slag (WGS), wet grinded phosphogypsum (WGPG), and wet grinded desulphurization gypsum (WGDG) were obtained in lab respectively. WGGBS-WGPG system and WGGBS-WGDG system were designed.
Alibaba offers 38 granulated blast furnace slag price products. About 47% of these are slag, 7% are abrasives, and 2% are industrial furnace.

Granulated Blast furnace Slag is the by - product obtained in the manufacture of pig Iron in blast furnaces at around 1400° to 1500°C in the molten form. The slag is obtained by rapidly chilling the molten ash from the furnace by means of chilled water and is ground about 400 m2/kg of fineness by using state of the art grinding mill to make GGBS.
After the granulated blast furnace slag is formed, it must be dewatered, dried and ground, using processes similar to those used with Portland cement clinker to make Portland cement. Typically, granulated slag is ground to an air-permeability (blaine) fineness exceeding that of Portland cement to obtain increased hydraulic activity at early ...
