Equipment reliability is always a priority for quarry and mine operators. The main drivers may change with commodity price swings, from maximizing output to keep up with high demand, to controlling operating costs in order to protect margins. But in every case, companies want their machines to spend more time out at work and less in the workshop for planned or unplanned maintenance. The fact that effective lubrication promotes reliability is unlikely to surprise many operators, as lubrication problems are the underlying cause of around half of all bearing failures in service. What may come as a surprise, however, is that an excess of lubricant can cause just as much damage as an insufficiency. Forcing too much lubricant into a bearing increases friction, raises operating temperatures and distorts seals.
