The waste tire refining production line has certain requirements for the tire size, mainly to facilitate feeding and ensure the cracking effect. Too large tires may not be able to enter the cracking furnace directly. It is recommended to use cutting equipment to cut the tires into suitable sizes before processing. Usually, the cut tires can better contact with the equipment and improve the heating and cracking efficiency. For different models of equipment, the manufacturer will provide a recommended tire size range, which can be adjusted according to actual needs.
