Success story
Specialty Lubricants in
Jinan Heavy Industries
Jinan Heavy Industries has officially commissioned the MQY6298, recognized by the on-site workshop director as the largest ball mill currently in operation within the global alumina industry. Designed for ultra-heavy-duty grinding applications, the MQY6298 represents a new benchmark in large-scale mineral processing equipment.
This new-generation mill adopts a direct-drive permanent-magnet motor (PMM) configuration, replacing traditional drive systems commonly used in alumina refineries. According to plant engineering personnel, the PMM direct-drive design delivers a 5% increase in grinding efficiency while simultaneously achieving a 5% reduction in overall electrical power consumption. These gains directly support industry demands for higher throughput, lower operating costs, and improved energy efficiency.
To ensure reliable lubrication under extreme loads, continuous vibration, and high thermal stress, the MQY6298 operates with Brugarolas BESLUX heavy-duty industrial lubricants, engineered for large open gears, hydrodynamic bearings, and critical rotating components. Brugarolas’ high-performance grease and open-gear lubrication technology provide enhanced film strength, wear protection, and long-term stability, supporting 24/7 refinery operations and reducing unplanned downtime.
The commissioning of the MQY6298 marks a major milestone for both Jinan Heavy Industries and the global alumina production sector, demonstrating how advanced drive systems and next-generation lubrication solutions can jointly elevate equipment availability, mechanical reliability, and overall plant productivity.

Open gear lubricant
Lubrication of open gears in cement plants requires special attention. Understanding proper lubrication should start from the gear installation process. BRUGAROLAS BESLUX CROWN, backed by decades of experience, has developed a comprehensive lubrication process for open gears.
During the normal lubrication phase, the selection of an appropriate adhesive lubricant (such as high-viscosity pure oil or fluid grease) should be based on factors like gear power, temperature variations, and environmental conditions. These lubricants must have suitable viscosity (adapted to equipment size, lubrication method, and temperature) and provide sufficient extreme pressure (EP) performance (e.g., four-ball welding load above 800 kg). Additionally, lubricants containing a proportion of solid additives are a better choice as they help meet extra load-bearing demands and offer emergency protection.
Typical new-generation lubricants:
- BESLUX CROWN 320 OG PLUS
- BESLUX CROWN 500 OG PLUS
