Every time the machine stops, it costs money. What should we do to prevent the stone crusher from "stopping in the middle of a shift"?

“Just one hour of stone crusher stoppage can evaporate hundreds of millions of dong.”

It is a reality that many mine owners face every day – even though the system still seems to be “operating smoothly”.
At a quarry in Dong Nai, in just one month, a jaw crusher motor failure in the middle of a shift caused the company to lose nearly VND250 million – including emergency repair costs, stopping the production line, and missing a contract to supply stone for a highway project.

“Every minute the machine is down, we lose money. But more frightening is the loss of reputation." - the mine owner shared.

5 “secrets” to help the stone crusher “run smoothly without stopping”

1. Installing an inverter – small investment, long-term profit

Many businesses were hesitant to spend tens of millions to install inverter. But in fact, this device helps:

• Reduces power consumption by 25–30%
• Increase motor life with soft starter
• Adjust grinding speed according to each type of stone, avoid overloading

2. Regular maintenance – change the mindset of “use it until it breaks, then fix it”

Not checking the jaw, forgetting to grease Bearing, leaving material lumps in the grinding chamber… These mistakes are repeated every day but are still overlooked.

Tip: Schedule regular maintenance and use a daily checklist for mechanics – just like car maintenance, regularity equals longevity.

3. Listen to the machine "beep" to save the machine

Unusual screeching noises, unusually increased vibrations – these are the machine's "warnings", which should not be ignored.
A worn eccentric shaft or cracked grinding chamber can cause an entire line to stop working unexpectedly.

4. Say no to cheap spare parts of unknown origin

No matter how good a machine is, if it has fake grinding jaws, poor quality balls, or bearings that do not meet specifications, it will not be able to operate for long.
Cheap first, expensive later is a painful lesson for many new companies in the industry.

5. Training machine operators – one mistake and they can't run

One off-center loading, one forgotten check of the oil tank… is enough to make the crushing station “lie down and breathe oxygen”.
Investing in human resources – from skills to thinking – is the most sustainable investment.

From engineering to business – every detail counts

A stone crusher is not just a mechanical device. It is the heart of the entire mining chain. If the heart stops beating, the entire cash flow will stop.
If you are looking to:

• Reduce electricity, reduce costs
• Increase output without investing in more machines
• Ensure uninterrupted progress

Start with the small things: clear maintenance schedule, well-trained technicians, and quality, standard spare parts.
