DRY SLAG GRANULATION WITH HEAT RECOVERY*
Dry Granulation Concept Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure 1) The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure 2)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 Dry slag granulation at a spinning disc Key Results/Findings A conceptual flowsheet has been developed in the 1 st year (by June 2007) of the project based on process modelling and focused(PDF) Heat Recovery from Slag through Dry GranulationDry 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 recoverHatch Ironmaking Technologies Dry Slag Granulation May 09, 2019 Primetals Technologies has developed a new innovative blast furnace dry slag granulation process with heat recovery at the voestalpine pilot plant in Linz, ADry Slag Granulation (DSG) YouTube
Economic and environmental evaluation of slag dry granulation
Like water granulation of slags, dry granulation could convert the vast quantity of BF slag produced globally (*400 Mt/year) into feedstock for cement and concrete production thus resulting incontent of the slag that comp licates copper recovery Beginning in the late 1960’s, bega n development of a co mplex, multifurnace dry granulation systems, (PDF) COPPER MATTE GRANULATION AT THE KENNECOTT UTAH COPPER SLAG TECHNICAL DATA SHEET PRODUCT: CDS IRON SILICATE EXPENDABLE ABRASIVE DESCRIPTION: A synthetic mineral blasting abrasive manufactured by granulation in water of the slag arising from copper smelting processes It is essentially an Iron Silicate with trace metals bound in an amorphous glass in the form of complex silicates and oxidesCOPPER SLAG TECHNICAL DATA SHEET CDS ConsultantsJun 25, 2016 And copper slag was low viscosity slag, so the length of ligament is shortest in the three kinds of metallurgical slag Meanwhile, copper slag is low surface tension slag, and a large number of small size solid particles obtained in copper slag granulation, as shown in Fig 3(c) Download : Download highres image (920KB)Experimental investigation on molten slag granulation for Dec 09, 2019 As a result of extensive RD in this area, the slagprocessing technologies are slowly converging around dry granulation combined with heat recovery In this paper, the slag granulation and heat recovery options are reviewed and given a critical evaluation, aiming to provide a basis for future directions in slag handlingGranulation and Heat Recovery from Metallurgical Slags
