The high electricity bills of a crushing production line are not due to the motor!
Many mine owners complain that despite running their equipment at full capacity and not significantly increasing output, their electricity bills exceed their limits every month. Everyone assumes it’s due to the motor’s high power consumption or expensive fuel, but few realize that the root cause of the high electricity bills often lies not in the power source, but in “unnecessary losses.”
A normally operating crushing production line should have stable and controllable electricity costs. However, in reality, material blockages, stalling, idling, improper clearances, excessive wear on wear parts, poor lubrication, belt slippage… every small problem is secretly consuming electricity.
To give a very intuitive example: Severe wear of the jaw plates/liners reduces the biting capacity, requiring repeated crushing, causing the current to surge by 20%–40%. For the same output, power consumption increases dramatically. Improper gap adjustment leads to poor discharge and material circulation, causing the equipment to operate under high load for extended periods, consuming tens of kilowatt-hours more per hour. Lubrication failure and increased bearing resistance force the motor to be overloaded, resulting in artificially high power consumption without improving efficiency. Even slight belt slippage can reduce output and increase power consumption; the lower the output, the higher the unit electricity cost.
The real way to save on electricity costs isn’t to reduce machine usage, but to operate equipment with “light load and high efficiency”: Replace wear-resistant parts promptly to maintain optimal crushing performance; regularly adjust clearances, tighten belts, and ensure stable feeding to avoid unnecessary work; maintain bearings and hydraulic systems properly to reduce operating resistance; and stock up on vulnerable parts in advance to avoid operating with defects and high consumption with low efficiency. Many customers have found that spending a few thousand yuan more each month on maintenance and stocking up can actually save tens of thousands of yuan in electricity costs, while increasing output by 10%–20%. This is far more cost-effective than simply “saving electricity.”
