Sažetak
In industry and power production and distribution large quantities of fine wastes are produced. These are above all fly ash and phosphogypsum. Attempts are made to use them as secondary raw materials in industry and construction. Since they contain dangerous and harmful components or are nonhomogeneous their direct application is limited so that they are treated as waste. This paper reports on tests conducted with the aim of agglomerating the mentioned fine industrial wastes by pelletisation. The aim of this resarch was to obtain agglomerated product suitable for handling, transport and dumping. At the same time efforts were made to incapsulate harmful components by producing pellets with protective shells. Next, pellets without binders and with different binders were produced. Strength, resistance to freezing and solubility of pellets were tested. All the fine industrial wastes under survey were found to be suitable for pelletisation. The utilisation of appropriate binders ensures pellet strength required for safe handling and ecologically sound deposition of pelleted Material.
