No One-Size-Fits-All Answer – It Depends on Your Situation

In my role coordinating equipment for a mid-tier aggregates company, I've handled 40+ rush orders in five years — including a 36-hour turnaround for a client whose primary jaw crusher seized up two days before a major asphalt pour. The most frustrating part? The same panic call always starts with: "What's the best crusher for an emergency?"

Honestly, there isn't one. The right machine depends on what kind of emergency you're facing. I've learned this the hard way — like the time the numbers said a fixed plant rental was cheaper, but my gut said we couldn't afford the 3-week setup (spoiler: gut won).

So I've broken down the three most common rush scenarios I've seen. Find yours, and we'll talk specific models.

Scenario A: Your Primary Crusher Just Went Down

Typical symptoms: Main jaw or cone failed — maybe bearing burnout, cracked frame, or a blockage that seized the motor. Production has stopped. Every hour of downtime costs $X (and you know what X is).

In this case, you need a plug-and-play replacement that can be operational in under 48 hours. The Kleemann MC 110i EVO2 is basically the gold standard here. Why?

  • It ships as a single mobile unit — no concrete foundation, no fixed installation. You crane it off the lowbed, connect power, and start feeding.
  • Feed capacity up to 330 mt/h (per manufacturer specs), which covers most mid-size quarry needs.
  • EVO2 technology reduces fuel consumption by about 15% compared to the previous generation (not that anyone cares about fuel in a crisis — but it does help long-term).

Real-world example: Last year, a limestone operation in Kentucky called on Friday afternoon — their primary jaw was down, and they had a rail contract due Monday. They rented an MC 110i EVO2 from a local dealer. Saturday morning it was crushing. Did they pay a premium? Sure — about 30% above standard rental. But missing that contract would have meant a $50,000 penalty clause. The certainty of delivery was worth way more than the savings.

One thing I'd do differently: I'd order wear parts (jaw dies, toggle plate) before the emergency happens. Looking back, I should have kept a spare set on the shelf. At the time, standard lead times seemed safe. They weren't — we had to pay $2,000 in air freight for a $500 part. (Note to self: never again.)

Scenario B: You Got a Surge Order and Need Extra Capacity

Situation: Your primary plant is running fine, but a customer just placed a 100,000-ton order that needs to ship in three weeks. You can't add a second shift fast enough — you need parallel crushing capacity on a separate feed.

Here, the question isn't just speed — it's product specification. What end product are you after?

  • For secondary/tertiary reduction (e.g., producing 0-20mm for asphalt), the Kleemann MCO 11i PRO is my go-to. It's a tracked cone crusher that works beautifully alongside an existing primary. Setup is a day, not a week.
  • For high-ratio reduction and cubical shaping (like concrete aggregates), the MR 130i EVO2 impact crusher shines. It's super aggressive — feed it up to 28" rock and it'll spit out 1.5" minus in one pass.

The tricky part: every spreadsheet analysis pointed to a cheaper impactor from a competing brand. Something felt off about their dealer support in our region. I went with my gut — and later learned that competitor had a history of weeks-long delays on parts for that model. Our MR 130i EVO2? We had a wear part delivered next-day from a local depot. That alone is probably worth the price difference.

Scenario C: You're Moving Operations to a Remote Site

The challenge: New pit. No existing infrastructure. No power lines. Minimal road access. You need a fully self-contained crushing spread that can be trucked in and running within a week.

This is where the whole Kleemann mobile ecosystem pays off. Not just one machine — you want a train: jaw, cone/impact, and screens, all interlinked.

For a recent greenfield project in West Texas, we deployed:

  • MC 110i EVO2 (primary jaw)
  • MCO 11i PRO (secondary cone)
  • Mobiscreen MS 19 D (double-deck screen)

All powered by a single generator set (the electric drives are efficient — we ran it on a 500 kW genset). The whole setup arrived in four truckloads and was crushing six days after the permit cleared.

The most frustrating part of remote deployments: site prep. You'd think a mobile plant means no prep — but you still need a level pad, drainage, and approach roads. That took us two days longer than estimated. My advice: budget an extra 3 days for groundwork, even with mobile gear.

How to Determine Which Scenario You're In

Before you call a dealer, ask yourself these three questions:

  1. Is your existing crusher completely down, or just under capacity? If down → Scenario A. If under capacity → Scenario B.
  2. How long do you have? Under 48 hours and you need production? Mobile jaw (Scenario A). Have a week or more? You can consider cone/impact setups (Scenario B/C).
  3. Is this a permanent new site or a temporary fill-in? Temporary → rent a single jaw. Permanent → invest in a full mobile spread (Scenario C).

One more thing: prevention beats cure. The 30 minutes I spend each quarter reviewing wear part inventory has saved us an estimated $15,000 in potential rework and rush shipping. A simple checklist — keep spare dies, belts, and filters on hand — is the cheapest insurance you can buy.

Bottom line: there's no universal emergency crusher. But if you know your scenario — downtime fill, capacity boost, or relocation — you can pick the right Kleemann machine and have it running before the deadline becomes a crisis. And honestly? That kind of peace of mind is way more valuable than the price premium you'll pay for the expedite.
