The slag granulation area links the hot slag runner of the blast furnace and the INBA dewatering system. This link is directly accomplished through the use of a granulation tank. The granulation tank creates a compact layout, which allows a reduced water circuit design with op- timal heat transfer conditions in addition to better product quality.Chat Online

Dry Slag Granulation Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.+
The presence of moisture requires dewatering the blast furnace slag before using it as an additive or as a mineral admixture to Portland cement. According to 1113, this cement increases strength, reduces permeability, improves resistance to chemical attack, and inhibits rebar corrosion.+
Today, blast furnace slag is a saleable product granulated slagsand for production of cement rather than a difficult and costly waste material. Paul Wurth has developed the INBA slag granulation process incorporating our proprietary dynamic INBA dewatering drum as the most popular and effective means of processing blast furnace slag in the world today.+
