Abstract: The paper analyzed problems existed in lubrication system of crusher of Pingshuo mining area, introduced working principle of an intelligent and centralized lubrication system and its system configuration, application solution and maintenance applied in Pingshuo mining area. The intelligent and centralized lubrication system combines PC and PLC with on-site multi-point lubrication pumps, smart meters and smart sensors, uses multi-point lubrication pump to achieve central lubrication of multi-points of the crusher, and uses electric pump to achieve grease auto-filling. Practical application showed that the intelligent and centralized lubrication system runs stably and reliably, improves working efficiency of equipment and reduces routine maintenance work.
