Belt life varies significantly based on material abrasiveness, loading conditions, maintenance practices, and operating hours. With proper maintenance, standard 2-ply or 3-ply rubber belting can last 15,000-30,000 operating hours (approximately 3-7 years) in moderate aggregate applications. Highly abrasive materials like crushed granite or sharp slag can reduce this to 8,000-15,000 hours. Key factors affecting belt life include proper belt tracking, adequate belt tension, material impact at loading point, belt cleanliness, and environmental exposure. Regular inspection of cover thickness and replacing the belt before complete failure prevents collateral damage to rollers and structure. Budget approximately $3,000-$5,000 for replacement belting on a 30×80 conveyor.
