选择建议

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. 腐蚀性介质：选择 316L 不锈钢部件或橡胶衬里。

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.).
