Research on the Performance of Iron Ore Pellets Containing Coal and Polyethylene
Abstract: Experimental researches on characteristics of the mixed pellets containing carbon which are made from pulverized coal mixed with polyethylene plastic and iron ore were carried out. The results show that under certain material particle size, moisture content percent and certain amount of bentonite conditions, cold state performance of pellets containing carbon mixed with addition of polyethylene plastic is reinforced, meaning that the more amount of plastic added in the mixed pellets, the better the cold strength to increase the strength of the dry bulb apparently. After the roasting reduction, strength of pulverized reductant polyethylene pellets with mixed rates of 1:1 (or 1:2) is better than that of pulverized coal pellet, and mineralogical analysis on polyethylene pellets shows that the addition of polyethylene plastic can improve the conditions of the reducing process heat and promote the reducing reaction, and the reducing area concentrates around the polyethylene plastic particles.
