Mining Crusher Lubrication System Optimization Project
Optimized and upgraded centralized lubrication system for mining crushers, improving equipment reliability and uptime.
Challenge
Open-pit mining crushers operate continuously in dusty environments with large day-night temperature variations. Bearing grease easily contaminated by dust, centralized lubrication lines frequently blocked; winter low temperatures caused poor grease fluidity, making startup difficult.
Solution
Upgraded to Denumine MP-3 extreme pressure lithium grease (-30°C to 150°C), combined with DENUKE intelligent centralized lubrication control system for timed and measured automatic lubrication. Added anti-blockage pipeline design and dust protection measures.
Results
Bearing failure downtime reduced by 75%, lubrication line blockage rate reduced by 90%, winter cold start time shortened by 60%, crusher annual uptime improved from 78% to 95%, annual downtime loss reduction of 1,500,000 RMB.
