Briquetting Burnt Dolomite Powder for Recycling in Steel Plants
Burnt dolomite powder is the by-product in preparing raw material in steel plants. It is treated as a solid waste in the steel industry case by its small particle size. This paper discusses the potential for utilizing burnt dolomite powder by briquetting with different binders include syrup, lime and ethoxyline resin. Burnt dolomite lumps of size 30mm could be used in slag splashing process. Moreover, compressive strength, curing time and effective MgO content in burnt dolomite lumps were considered in experiment. Experiments results found that the burnt dolomite lumps with 0.9% resin binder have the best compressive strength, 20.86Mpa. Additionally, the dolomite lumps with syrup or lime binder have an excellent chemical composition of high content of active MgO and low free water content.
