Operating conditions in the cement industry are among the harshest, causing significant wear on conveyor belts. Materials often adhere to idlers, turning them into abrasive drum sanders that degrade belts quickly. The extreme heat from the clinker accelerates cover aging, causing hardening and cracking. Additionally, belts used on primary and secondary crushers require a carcass strong enough to withstand heavy impact, ripping and tearing caused by large lumps of heavy, sharp materials, either falling from height or becoming trapped.
