concrete.6 A national standard for ^the ground granulated blast furnace slag powder used for cement and concrete was issued (GB18046-2008). Since then, the application of ground granulated blast furnace slag is generalised. From 2000, China began to build production lines to produce the ground granulated blast furnace slag
temperature of about 1,500°C) with a jet of high-pressure water. Granulated slag is vitreous and looks sandy. It is similar in chemical composition to Portland cement and hardens when it reacts with wa-ter. Therefore, about 80% of granulated slag is used as a raw materi-al for cement. The remaining about 20% of blast furnace slag is air-
slag-water system is important. This includes the spatial relationship of the streams of slag and water during impact and the ratio of their masses and velocities at this moment. Thus, a great deal of attention has been paid to the formation of the water and slag streams during granulation.
Metjod includes feeding of formed during the beading mixture of granulated material and water into the tank for granulation. Then mixture is fed to the facility fir dewatering for water separation from granulated material.

Nov 28, 1978· The hot mixture of solid slag particles and water produced by contacting water with the molten slag released from a blast furnace is introduced into a tank equipped with an overflow and a filter at the overflow which permits a portion of the water and a minor fraction of slag fines to overflow.
Today rapid cooling of liquid slag in a closed water slag granulation plant is state of the art process. The rapid cooling of the liquid BF slag in the water prevents the crystallization of slag and breaks the slag into small particles by thermal stress. The liquid BF slag freezes in an amorphous granulate, called granulated BF slag.
