Physical and chemical and mineralogical characteristics of LD steel slag. It has been found that the density of LD slag lies between 3.3-3.6g/cm. 3 Due to its high Fe content, steel slag looks in appearance a loose collection, and appears hard and wear resistant. The grindability index of steel slag is 0.7, in contrast with the value of 0.96 and 1.0 for blast furnae slag and standard sand ...
Slag sand and slag wool are formed by a method wherein molten slag is poured at a temperature above 1300° C. in a thin flowing stream onto a vaned drum rotating at a peripheral speed of at least 25 m/sec. This drum, which may have forwardly directed nozzles for mixing the falling slag stream with a cooling medium such as water, breaks the slag up into droplets and projects these droplets ...
Apr 01, 2008· The steel slag was mixed with other raw materials, such as limestone, clay, sand, and bauxite, in appropriate proportions in order to produce the raw meal to be tested for the production of Portland cement clinker ((PC) S/S).A reference raw meal ((PC) Ref), without steel slag, was also synthesized for reasons of comparison.The chemical analyses of the raw materials used are given in .
Nov 04, 2013· re Clinker grindability. Some years ago I had some grindability testing done by Magotteaux. Two separate tests were performed, the first was the SGI test which assessed the number of revolutions within a test mill that were required to produce a surface area of 350 m2/kg. The second was a breakability test which assessed the height that a

Nov 25, 2018· The slag aggregate concretes are usually made with slag coarse aggregate and natural sand fine aggregate for workability. Structural dead loads are decreased because the unit weights of the slag concretes are normally around 160 kg/cum less than those obtained with other types of aggregates.

Hardgrove Grindability Index - Wikipedia . Hardgrove Grindability Index (short HGI) is a measure for the grindability of coal. Grindability is an index, therefore it has no unit.
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.
Foundry sand consists primarily of clean, uniformly sized, high-quality silica sand or lake sand that is bonded to form molds for ferrous (iron and steel) and nonferrous (copper, aluminum, brass) metal castings. Although these sands are clean prior to use, after casting they may contain Ferrous (iron and steel) industries account for ...
