If you landed here, there's a good chance you typed one of these into Google: "kleemann," "mr100 kleemann," "mike kleemann," or a search that got cut off mid-sentence. I look at our search analytics once a quarter, and some of the same odd phrases keep showing up. This page is my attempt to actually answer them.

Who's talking? I'm a parts and rental coordinator for a Kleemann distributor. I've handled well over 1,200 rush orders in 11 years, including same-day turnarounds for contractors who were facing penalty-laden deadlines. This FAQ is what I tell those callers, minus the hold music.

Here's what we're covering:

1. Is a used Kleemann MR 100 worth it for a small operation?

Short answer: yes, if the machine's been looked after. The MR 100 Kleemann is one of those models that refuses to die — which is exactly why you're still searching for it. It's a compact impact crusher built for recycling and smaller aggregates jobs. It's not a big producer, but it's mobile, it starts, and it makes money.

The most honest advice I can give: the previous owner matters more than the model year. A 2010 MR 100 that's lived in the same quarry its whole life with one experienced operator is a safer purchase than a 2015 machine that's bounced through five rental fleets. We've seen both outcomes, and guess which one failed first. On any used machine, check the emergency stops and remote-control functions — according to ISO 21873-2, which covers safety requirements for mobile crushers, those systems have strict requirements for a reason.

And don't let anyone in this industry treat a small order like a nuisance. The vendors who took my small orders seriously when I was starting out are the ones I still go to for the big stuff. A one-machine contractor can generate $25,000 of crushing in a good week. That's real money, and it deserves real service.

2. What's the difference between the MR 100 and the current EVO2 crushers?

The MR 100 belongs to an older generation. It was Kleemann's entry-level impact crusher before the MR 110 and MR 130 took over that role. The current EVO2 line brought a cleaner direct drive, easier access for wear-part changes, and the SPECTIVE operating system that shows the operator what the machine is doing in real time.

In practical terms, here's the gap: a healthy MR 100 with the right rotor settings sits around 200 tonnes per hour in typical limestone. An MR 110i EVO2 will do 300-plus. For a small recycling job, 200 is plenty — you're probably limited by the excavator feeding it anyway. For a highway aggregate contract with a deadline, you'll want the newer machine.

Other differences from our rental logs:

  • The MR 100 needs manual gap adjustments more often. An operator who knows the machine gets noticeably more from it.
  • EVO2 models use less fuel. In our side-by-side rental comparisons, we measured roughly 15-20% better fuel efficiency with the newer machines.
  • Parts, obviously, are easier for the current line. We still stock MR 100 wear parts — blow bars, cheek plates, belts — but a full rotor assembly comes from Germany, and that's a 6-8 week lead time.

(I should double-check those fuel numbers before quoting them anywhere official. That comparison was two specific machines, not a controlled test.)

3. How fast can I get parts when my Kleemann goes down?

This is my world. In my role coordinating parts and rentals for crushing contractors, the first question is never "when would you like it?" It's "what's the date that makes the job impossible?"

For standard wear parts — blow bars, screens, belts, sensors — we carry stock and can ship same-day if the call comes before noon. In March 2024, a one-man contractor called at 3:45 on a Thursday. His MR 100 threw a blow bar, and he had a bridge job starting Monday. Normal lead time was five days. We pulled a replacement from a rental machine, got it on the evening flight, and the customer paid $180 in rush freight on top of the $700 part. He made Monday. The alternative was watching a competitor with a working crusher take the job.

Long-lead components are a different story. A rotor, a main bearing housing, a crusher chamber — those are built in Germany, and you're looking at weeks, not days. That's why our policy is worst-case lead time first. I'd rather lose an order by saying six weeks than lose a customer by promising Wednesday and delivering in August.

Quote the honest lead time first. The customer who knows the worst case can plan around it; the customer who's told what they want to hear won't call you again.

Based on our internal data from 1,200+ rush jobs, about 70% of breakdown calls are wear parts and sensors — things that belong in a preventive maintenance kit. Keep one on the shelf and you've just cut your failure risk by about two-thirds. And no, we don't push smaller customers to the back of the queue. A single-machine contractor often has less tolerance for downtime than a big quarry with redundancy. That's our numbers for our region — a distributor on the other side of the country will have different stock and different freight options.

4. What does it actually cost to run an older Kleemann?

I wish I had a clean spreadsheet for this. Our rental fleet's maintenance logs were never designed for analysis, so I can't give you a controlled study (mental note: fix that someday). What I can say anecdotally, after years of watching machines come and go:

  • Wear parts. Impact crushers like the MR 100 chew through blow bars based on what you feed them. Clean limestone can see 5,000 hours from a set; demolition rubble with rebar can kill them in 800. A realistic annual budget is two to three sets.
  • Fuel. An MR 100 under load uses somewhere in the region of 30-40 litres per hour, depending on rotor speed, gap setting, and feed material. That's what the fuel gauge says, not what the brochure says.
  • Maintenance. The basics — belt inspection, fluids, greasing, checking the magnet — are a half-day job. Count on 4-6 hours of service per 250 operating hours.

If you're a small operator, think in cost per tonne, not purchase price. It took me four years and a drawer full of fuel receipts to understand that. We've rented the same MR 100 out 22 times in two years; it's paid for itself twice over. The customers who treat the machine properly and return it clean are the ones we quietly quote better rates to. Small doesn't mean unimportant — it means potential.

5. The searches that land here: "Mike Kleemann," "Henry Stats," "Robert," "how many legs does a..."

Every quarter I pull the search terms, and these keep showing up. Since you took the time to type them, here's the actually-useful version.

"Mike Kleemann." If you're looking for a person with that name, I can't point you to one at Kleemann GmbH. The manufacturer is part of the Wirtgen Group (which has been part of John Deere since 2017), and the people who can actually help you sit in the distributor network, not head office. Call your regional distributor and ask for the sales manager who covers your state. It's faster than emailing a general address in Germany.

"Henry Stats." Either you found this name somewhere and lost the context, or you're looking for machine statistics. If it's the latter, here's the short version for the MR 100: roughly 200 tonnes per hour, feed size up to about 500 mm, transport weight around 40 tonnes. If it's the former, I honestly don't know who Henry Stats is. He's not in our CRM and not in the manufacturer's directory I can access. Maybe you're misremembering a dealer contact.

"Robert." This one's more common than you'd think. People call us, talk to "a Robert," then search the name later to find the company. If it was our branch, calling any of our locations with an approximate date will pull up the call record. Fair warning: there are three Roberts in our office. We try not to confuse them.

"How many legs does a..." You didn't finish the sentence, so I'll cover the likely options. A spider has eight. A dog has four. And a track-mounted crusher has two — two tracks, not legs. It can tram around a job site at 1-2 km/h, but moving between sites requires a trailer. If that's the question you were trying to finish, you're welcome.

(And yes, I know this section reads like a confession. That's kinda the point.)

6. Should I buy Kleemann, or another brand?

I can't answer that, and anyone who tells you their brand is better across the board is reading from a brochure. According to USGS Mineral Commodity Summaries (2024), the United States produced about 1.5 billion tonnes of crushed stone in 2023 — it's a huge market with many different machines earning their keep in it. What I can do is give you the questions to ask any dealer before you commit:

  • Where are parts stocked? The best machine on paper is useless if every part crosses an ocean. We keep a local warehouse; not every dealer does. Ask to see it.
  • Who trains your operator? A mobile crusher is forgiving when it's new and punishing when it's set up wrong. Commissioning support matters more than a feature list.
  • What happens when the machine breaks? Phone support? Rental backup? A loaner if the repair exceeds five working days? That last one isn't standard. Our customers who run a single machine get a rental replacement from our fleet if their unit is down for more than five working days.

When I compared how we treat small contractors vs. the big quarries, I found we were spending more time on paperwork than on the people running the machines. We changed that. Now a two-machine contractor gets the same "what's your deadline?" treatment as the largest site in the state. That's not charity — it's why our smaller customers stay with us when they grow.
