Selection suggestions
1. High hardness ore (such as iron ore): It is recommended to configure the power ≥1250kW, and the liner should be made of high chromium alloy.
2. Corrosive media: Choose 316L stainless steel components or rubber lining.
3. Maintenance points: Check the gear meshing clearance every 500 hours Replace the
bearing lubricant every 3000 hours If need a performance curve (QH) or wear test report, please explain the specific working conditions (such as ore hardness, grinding concentration, etc.).
