ABSTACT Organic binders are often desired when making low-silica iron ore pellets. Corn and wheat are grown in large quantities near certain iron ore pelletizing facilities and their starches are easily modified to form cold-water-soluble powders that can be used as binders. We investigated how starch cold-water solubility, starch dose, starch …Web

Abstract. Size enlargement by agglomeration is a unit operation of mechanical process technology 1 (Fig. 6.1). This field deals with the transport phenomena and changes of state of particulate matter which in most cases is solid but can also be liquid (droplets) and, in a few special cases, gaseous (microencapsulated).Web
