Pulkit Khemka explains on the role of lubrication in mining equipment and the selection of lubricants.
Statistically every single ton of metal produced creates the demand of 1 million litre of lubricant oil. The market for lubricants product in country is estimated at 2.2 billion litre annually.
Lubricants play vital role in performance of mining equipment. Different equipment require different type of lubricants to smooth operation. Mechanical loads cumulatively result in a high wear rate of bearings and friction points. Lubrication is therefore absolutely necessary in order to provide the right protection. Most of the critical application is regarding the hydraulic system and bearing.
Hydraulic system has to perform in the extreme condition like high temperature and load. Variation in temperature reduce the oil viscosity result in more wear out of machine parts. To avoid the failure or damage, hydraulic oil should be strong enough to sustain the temperature variation. Selectively chosen quality base oil with balance additive formulation helps to maintain the viscosity during the temperature fluctuation.
Bearing lubrication is one of the critical and focus point of lubrication in mining equipment. Big size mining equipment apply high load on the bearing to do work flexibly, it increases the more wear out of bearing foretell the failure of bearing which impact on the equipment reliability and productivity.
Grease composed of EP additive with refined based oil and suitable thickener function well and maintain the lubrication during the high load to reduce the bearing damaged or failure. It avoid the downtime of equipment which cost more than lubrication cost in mining industry. Choosing the best lubricant is dependent upon various factor in mining industry.
