The service life of an organic fertilizer granualtors varies considerably depending on the quality of its components, the intensity of use, and maintenance. A reasonable service life is typically 8-15 years, depending on the following factors: For core components, the transmission system (motor, bearings, etc.) using high-quality parts and regular lubrication can last 4-6 years with 8 hours of daily operation, but this shortens to 3-4 years under full load. Forming components (drum liners, molds, etc.) using high-manganese steel or tungsten carbide coating have a lifespan of 2-3 years, but this is shortened by one-third when handling sandy raw materials. The control system with a dust removal device can maintain a lifespan of 5-8 years; otherwise, it is prone to failure within 1-2 years.

The overall machine lifespan varies depending on the type: Small drum granualtors (1-3 tons per hour) with proper maintenance (regular cleaning, belt replacement) can last 8-10 years; otherwise, a major overhaul is required every 5 years. Medium-sized extrusion granulators (5-10 tons per hour) with regular mold repair can last 10-15 years. Large intelligent fertilizer granualting produciton lines with full-cycle maintenance and component upgrades can last 15-20 years. Extending the service life requires pre-treating raw materials (particle size ≤ 2mm), using special lubricating grease, and controlling the load (not exceeding 110% of the rated load). In short, "equipment accounts for 30% of the cost, maintenance accounts for 70%," and with proper operation, some equipment can last more than 20 years.
