In heavy industries like mining and metallurgy, ball mills are core equipment for material pulverization. Their operational stability is directly related to production efficiency and equipment life. The lubricating oil hydraulic support system, a key component supporting the ball mill's bearings, achieves load balancing, vibration and noise reduction, and temperature control through the synergistic effect of hydraulic and lubrication technologies. This article systematically analyzes the system's structure, operating principle, and key maintenance points.

System Components and Functions
1. Hydraulic Support Unit
Hydraulic cylinder assembly: Constructed from high-strength alloy steel, with a precision piston rod and sealing rings, supports the weight of the ball mill cylinder via hydraulic oil pressure (typically 15-25 MPa).
Accumulator: Absorbs shock loads and prevents mechanical damage caused by transient pressure fluctuations.

2. Lubrication System
Dual oil supply: The main oil circuit (pressure lubrication) and the auxiliary oil circuit (splash lubrication) complement each other to ensure adequate lubrication of the bearings under both high and low speed conditions. Intelligent Temperature Control Module: Integrates a PT100 temperature sensor and proportional valve to adjust the oil temperature in real time (recommended 40-60°C) to prevent abnormal lubricant viscosity.

3. Monitoring and Protection
Pressure Sensor Array: Collects pressure data at each support point in real time, triggering an alarm if the deviation exceeds ±5%.
Oil Contamination Detection: A particle counter monitors ISO 4406 cleanliness levels (must be maintained ≤ 14/11).

Conclusion
The lubricating oil hydraulic support system is the "invisible pillar" of efficient ball mill operation. Through a combination of scientific selection, precise maintenance, and intelligent monitoring, the equipment overhaul cycle can be significantly extended (by an average of 30%-40%). In the future, with the application of digital twin technology, this system will enable even more refined health management.
