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. . Production Process by Ball Mill. Slag is transported into the plant by truck .
The main constituents of blast furnace slag are CaO SiO2 Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder known as ground granulated blast furnace slag cement.
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 increased.
Granulated blast-furnace slag was prepared from Isfahan steel complex located in Isfahan province Iran. The prepared slag was firstly ground in a laboratory ball mill to attain a Blaine specific surface area of 340 m2kg. The chemical composition and the specific surface area of the blast-furnace slag are given in Table 1 and Figu-

Buy blast furnace slag ball mill to make ground granulated blast-furnace slag GGBS. GGBS is the raw material of cement and concrete. Click for details.
Traditionally standard ball mills have been used but since the early 2000s the use of roller presses and vertical mills has increased. Granulated blastfurnace slag is a very hard material and as a result necessitates the use of high wear resistant materials in the grinding process. The grinding process takes account of mean particle size grading particle size distribution fineness and the particle shape in order to ensure that when used in
Ground Granulated Blast-Furnace Slag. Slag is a by-product from steel plants which is obtained from blast furnaces during the separation of iron from iron ore. The process involves cooling of the slag through high-pressure water jets this leads to formation of granular particles. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press
Dec 12 2019 The blast furnace slag can be crushed and processed into blast furnace slag aggregate by roller crusher and ground granulated blast furnace slag by ball mill. These two materials can be widely used in construction infrastructure and agriculture. Blast furnace slag aggregate
