1. Official Noise Data Should Be Confirmed
- Exact running noise should be confirmed from the manufacturer specification sheet.
- Y81PTZ is a fully automatic scrap baling line with PLC control and large feeding hopper.
- No published decibel value is available for this specific PTZ model.
- Without an official noise test report, only general Y81 series characteristics can be used as reference.
2. Hydraulic Drive Is Usually Not Extremely Loud
- Y81 series hydraulic metal balers are driven by hydraulic cylinders and pumps, not high‑speed cutting or hammering.
- Working motion is generally steady and relatively stable.
- Compared with shredders, crushers, or hammer mills, scrap balers usually produce lower continuous mechanical noise.
3. Main Noise Sources Come from Motor & Impact
- Main sources: hydraulic pump station, electric motor, cylinder movement, metal feeding, and scrap impact inside the press box.
- If mixed heavy steel, hollow pipes, or uneven scrap are fed suddenly, impact noise may increase.
- Automatic feeding and discharge systems may add background noise from conveyors or moving parts.
4. Site Layout & Maintenance Reduce Noise Impact
- For export projects, request nameplate noise level, hydraulic pump type, motor power, and enclosure design.
- If installed near offices or residential areas, use enclosed workshop, rubber pads, and sound insulation panels.
- Regular hydraulic oil and pump inspection can help reduce noise complaints.
