Quality of the Grinding Disc in Grain Pulverizers Does Not Affect Lubrication: It is important to monitor the newly replaced grinding disc in real-time to observe its impact on the lubrication system. Regular analysis of the lubricant is also crucial to ensure that it meets the required standards for effective lubrication.

Inadequate Cooling System Performance: The cooling system in the lubrication setup uses a Basker water cooler to dissipate heat from the lubricant. However, upon touching the oil pipes entering and exiting the cooler during operation, only a slight temperature difference was felt, indicating that a single cooler was insufficient. The heat exchange between the cooling water and the lubricant was too short. To address this, a second cooler was added in series, with the outlet pipe of the first cooler connected to the inlet pipe of the second cooler. This modification extended the heat exchange time.

Post-modification Results: After the upgrade, the oil temperature in the fully loaded fine cone crushers never exceeded 51°C, keeping it within the safe range for operation. This ensured that the cone crusher could run continuously without the need for shutdowns, significantly enhancing its production capacity and system efficiency while reducing power consumption. The economic benefits from these improvements were substantial.

Conclusion: The upgrade of the cooling systems in both fine cone crushers at our plant successfully resolved the long-standing issue of high oil temperatures in the lubrication system of the 84" hydraulic cone crushers. This solution not only supported the implementation of a more efficient "one medium, two fines" production process but also boosted our plant's crushing capacity and system efficiency, providing strong support for meeting our annual production targets.
