Frequently Asked Questions
What is the advantage of gear drive over belt drive in feed pellet mills? ▼
Gear drive offers 20% higher transmission efficiency and longer lifespan. Belt drive slips under heavy load, causing inconsistent pellet quality and higher energy consumption.
How often do the ring die and roller shells need replacement? ▼
Ring die lifespan is typically 1,000-2,000 hours depending on material and feed formulation. Roller shells usually need replacement every 600-800 hours. We recommend keeping spare sets to minimize downtime.
