What bearings are used in cement plants: Industry hot spots and selection guide
Recently, the cement industry has become a hot topic due to the upgrade of environmental protection policies and the intelligent transformation of equipment. According to network-wide data monitoring, in the past 10 days, the search volume for keywords such as "cement plant equipment maintenance" and "bearing selection technology" increased by 35%. This article will combine industry hot spots to analyze the key points of bearing selection for key equipment in cement plants, and attach structured data for reference.
1. Popular equipment and bearing requirements in cement plants
The 2023 industry report shows that the following equipment has the highest bearing failure rate and needs to be focused on:
| Device name | Bearing type | Average life span (months) | Main cause of failure |
|---|---|---|---|
| ball mill | Spherical roller bearings | 12-18 | Axial impact load |
| Rotary kiln | Cylindrical roller bearings | 24-36 | High temperature deformation |
| Crusher | Tapered roller bearings | 8-12 | dust pollution |
2. Recent industry hot events
1.Implementation of new environmental protection regulations: Many places require cement plants to complete equipment noise reduction renovations by 2024, and the demand for low-vibration bearings has increased by 40%.
2.Popularization of intelligent monitoring systems: Q2 data in 2023 shows that 56% of large cement plants have installed bearing temperature real-time monitoring devices
3.Import substitution accelerates: The market share of domestic bearings in the cement industry will increase from 32% in 2020 to 58% in 2023
3. Comparison of core parameters for bearing selection
| parameter | Applicable models of ball mill | Applicable models of rotary kiln | Applicable models of crusher |
|---|---|---|---|
| load capacity | ≥240kN | ≥180kN | ≥300kN |
| Speed range | 50-200rpm | 3-5rpm | 500-800rpm |
| working temperature | -20℃~120℃ | 120℃~250℃ | -30℃~80℃ |
4. Latest technology trends
1.Ceramic hybrid bearings: It can reduce the friction coefficient by 35% in fan applications, becoming the focus of the 2023 technical seminar
2.Self-lubricating bearings: Suitable for vertical mill equipment that is difficult to maintain, extending the maintenance cycle by 3 times
3.Smart bearings: SKF Insight series bearings with built-in sensors achieved a fault warning accuracy of 92% in the pilot factory
5. Suggestions for selection
According to the "White Paper on Selection of Bearings for Cement Equipment" released in July 2023, it is recommended:
| Working conditions | Preferred brand | Cost-effective solution | Budget savings (%) |
|---|---|---|---|
| High temperature and heavy load | NSK | ZW | 45 |
| high speed impact | SKF | HRB | 38 |
| Dust environment | FAG | LYC | 52 |
Conclusion
As the cement industry transforms towards intelligence and greening, bearing selection needs to comprehensively consider equipment operating conditions, maintenance costs and technological innovation. It is recommended that enterprises conduct bearing status testing regularly (every 6 months) and refer to the latest industry standard GB/T 29717-2023 for equipment upgrades.
