Generally, wet granulation plants are used to cool down and process the material, using large quantities of waterit can take more than eight tons of water to treat one ton of slag.The newest technology ECOFERTEC slag processing plant enables the most cost-effective way to remove steel from slag with 300 tonh capacity. One plant can handle 1,5 M ton of slag per year in two shifts. Ecofertec designed processes has always the highest processing rate and the lowest electricity consumption possible for each solution.The most common process for granulating blast furnace slag involves the use of high water volume, high pressure water jets in direct contact with the molten blast furnace slag at a ratio of approximately 10 to 1 by mass. The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a 4 sieve.
