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
