 HCG Dry Drum Magnetic Pre Separator Operation & Maintenance Guide
                               

 

Installation & Startup

▪ Install on a level floor (≤2mm/m²). Power supply: 380V±10%. Ambient temperature: -20°C to 60°C.

▪ Pre-start check: Ensure drum rotation matches directional markings. Lubricate bearings with No. 2 calcium-based grease. Verify gearbox oil level.

Operation

Start the pre separator or system empty for 30 minutes. Gradually feed material up to 50% load. Adjust drum speed (40-200 RPM) via the frequency converter.
Key adjustment: Fine-tune the magnetic angle using the adjustment rod.
