Pellet Machine Unstable Current: Causes & Quick Fixes
TIME:2026-01-05 14:59:27 WRITER：JINAN GLOBAL MACHINE MANUFACTURER
Unstable current in pellet machines disrupts production efficiency and pellet quality. Here’s a simplified breakdown of causes and quick fixes:
Unstable motor voltage or a faulty ammeter often triggers fluctuations—check power supply stability and calibrate/replace the ammeter. Uneven feeding or inconsistent raw material size leads to intermittent operation: adjust feeder speed and screen materials for uniform granularity. Raw material impurities (iron, stones) or moisture outside the 10-15% optimal range disrupt molding—remove impurities and control moisture strictly.
Worn parts (material lifting blade, bearings) cause issues too: replace worn blades, swap out damaged bearings, and lubricate regularly. Improper roller-die gap (ideal 0.1-0.3mm) or mismatched compression ratio affects current—adjust the gap and fine-tune compression based on raw materials. Loose transmission components (belts, fasteners) lead to irregular operation: inspect and tighten parts periodically.
Addressing these key factors resolves current instability, reduces downtime, and ensures consistent performance. For expert support, contact our 20-year biomass equipment team.
