Ask any quarry operator why the first crush of the day is called 'breakfast', and most of them will say the same thing: the machine is breaking its overnight fast. That's it. No hidden meaning. It's the same root as the morning meal. I've thought about that a lot when a Kleemann crusher goes down at 6:30 in the morning, because 'breakfast' is exactly what you're trying to get the plant to do—start reliably and feed itself before the day gets complicated.

I'm a service coordinator for a company that handles fleets of mobile crushing and screening equipment. After 200+ rush jobs in the last few years, I can tell you there is no single correct answer to 'What do I do when my crusher is down?' It depends on how much uptime you need, how fast you need it, and how willing you are to accept risk. This is a decision tree, not a one-size-fits-all article. Here are the three scenarios I use when triaging a request.

Why is it called breakfast?

If you've ever asked why is it called breakfast, the answer is simpler than you'd think. 'Breakfast' literally means breaking the overnight fast. In a crushing operation, the first material run after a cold start has the same name in some crews. It's the moment the plant wakes up, warms up, and starts producing. When I'm triaging a rush repair, I always ask about that first run. It tells me whether the problem is a bad sensor, a hydraulic leak, or something in the feed system.

Scenario A: You need a part by tomorrow morning

This is the one I see most often. You're at a job site in late afternoon, the mobile jaw crusher starts to lose feed, and the fault screen points to the level sensor. Normal part delivery is five days. The client has a foundation pour tomorrow and needs 2,000 tons of bedding aggregate by noon.

First thing I do is ask the dealer for a genuine part number and an exact price. If someone offers an aftermarket 'equivalent' for the Kleemann LSD, I get cautious. According to the Kleemann documentation for the EVO2 generation, the LSD, or Level Sensing Device, is part of the standard feed control package. It's not just a spare part. A mismatch in resistance or signal type can make the crusher overfeed or underfeed. A $400 aftermarket sensor can turn into a $4,000 diagnostic bill.

I ran this calculation once with a parts vendor. The aftermarket sensor would have saved about $400. The worst case was a damaged crusher chamber and three days of downtime. The best case was that it worked. The expected value said maybe, but the downside was too big. I ordered the OEM part.

Before you approve rush freight, get the total landed cost in writing. I learned this after agreeing to a $300 same-day courier fee that showed up as a $900 'expedited handling surcharge.' The vendor who lists all fees upfront—even if the total looks high—usually costs less in the end. If a vendor says 'fine, we'll sort out charges later,' you're not getting a discount. You're getting a surprise.

Scenario B: You need short-term crushing capacity

Sometimes the machine isn't broken—you just don't have enough production. Since 2023, I've seen this spike with infrastructure work around the Alps. With skiing Milano Cortina 2026 edging closer, contractors are mobilizing for access roads, slope stabilization, and tunnel spoil processing. A project might need 30,000 tons of crushed material over ten weeks. Buying a plant for that doesn't make sense. Renting a Kleemann MR 130i EVO2 might.

But watch the quote. A lot of rental prices look aggressive until you add transport, mobilization, dust suppression, fuel, and the operator's travel time. Ask for every line item before you sign. If a rental company bundles everything into one number, ask what's not included. The vendor who says 'it's all in there' with no breakdown is the one who'll call you about an 'environmental compliance fee' later.

In my first year, I made the classic short-term rental mistake: I looked at the daily rate and completely ignored the transport math. The rental itself was $2,800 per week, but the transport from the depot to the mountain site was $3,500 because the machine required a special trailer and an escort vehicle. I should have asked for a delivered price.

At the Second Congress on Aggregates and Construction Materials in Milan in 2024, Florian Kleemann, a service engineer who has spent years on EVO2 fleets, made a point I still use:

'A rental agreement is not a service agreement. If the machine sits idle because the site isn't ready, whose clock is running?'

That question saved me more than once. If the contract doesn't clearly define response times and standby responsibility, you're buying a dispute. I also ask for a small stock of wear parts to stay on site: two blow bars, a set of belt scrapers, and a spare sensor. The cost of carrying those parts is tiny compared to one stalled shift.

Scenario C: You're investing for the long haul

Long-term is different. If you're buying a Kleemann MOBICONE MCO 9i EVO2 to feed a fixed screening plant, the purchase price is not the number to obsess over. The number that matters is cost per ton over five years.

I've seen buyers compare a used machine against a new one and take the used machine purely because of the lower sticker. On paper it made sense. But the used machine had an intermittent LSD fault and a wiring harness that had been repaired twice. The new machine cost more at purchase, but it delivered more uptime in the first year. I don't know the exact payback period for your site, but the logic is universal: get the machine's diagnostic history and maintenance records before you negotiate.

This is also where the fixed-plant temptation gets dangerous. To be fair, a stationary plant can have a lower cost per ton if your deposit is stable and you're not planning to move. But if the resource moves, or the deposit is at multiple spots, a mobile Kleemann plant lets you relocate instead of reinvest. I'm not saying mobile is always right. I'm saying the answer depends on your deposit, your permit, and your timeline.

For used machines, ask for the full component status report: crusher wear, screen tension, engine hours, hydraulic filter history, and the fault log from the control system. If a seller hesitates, that's a red flag. Transparent documentation is worth more than a smooth sales pitch. We didn't have a formal handover checklist for used machines, and the third time a buyer found the previous operator's feed settings still in the control unit, I realized the problem was our process. Now every pre-delivery inspection includes a control-unit reset and a documented breakfast run.

Which scenario are you in?

Here's a rough way to sort it:

  • If the machine is down and the project is in hours, you're in Scenario A. Buy the correct part, pay for expedited delivery, and get the vendor's fee breakdown in writing.
  • If the machine is running but you need more production for weeks or months, you're in Scenario B. Rent, but only after you've checked transport, setup, standby, and wear parts line by line.
  • If the plan is years, you're in Scenario C. Buy for cost per ton, not sticker price, and make the seller prove the machine's history.

I also use a 48-hour buffer rule. Anything that can be prepaid or pre-checked should be. The goal is to avoid the moment where the only option is to accept a vague price and hope.

One last thing. When the machine is fixed and the site is quiet, run the plant empty for a few minutes before you feed it. That's the breakfast run. It won't solve every problem, but it will tell you if the repair was just a patch or an actual fix. And now you know why it's called that.
