In the granulation section, the liquid slag is ‘quenched’ by pouring onto it an excess water stream The evaporated water will be condensed in a condensing tower located above the granulation tank This proven granulation process 23082016 The energy in slag is lost through dumping and water granulation processes, and where slag is sold as a byproduct, it is for its chemical content only Here, dry granulation processes also offer advantages including the production of byproducts which hold value in both their chemical content and physical properties and heat recoveryDry Slag Granulation: A Path to Improving the Safety and Hatch09122019 The granulation processes employ mechanical impact or highpressure fluids (eg air or water) to break up the slag into small granules of typically 1–5 mm There are several different methods to granulate or atomise the slag, which can be categorized broadly into the wet and dry granulation methodsGranulation and Heat Recovery from Metallurgical Slags

Slag recycling recovery

There are various processes on the market for the granulation of blast furnace slag The most important process is cooling in a water bath The most common methods are the RASA system from Rasa Corporation, the INBA system (Fig Average Slag Flow 3040 [ton/hour] Duration of granulation ~ 60 [min] Granulated slag 3040 [ton] Temperature of fluidized bed / granulate discharging temperature ~ 200 [°C] Total process air flow ~ 170,000 [Nm³/h]AISTech2018 Dry Slag Granulation Primetals TechnologiesThe granulating method comprises the following steps: liquid steel slag enters the dryprocess granulator through the feeding device and is granulated into fine steel slag granules,CNB Liquid steel slag dryprocess granulating
