Kleemann Mobile Crushers: 8 Questions a Quality Inspector Actually Gets Asked

I'm a quality compliance manager for an authorized Kleemann distributor. I review every machine before it reaches the customer—roughly 200 units a year, mostly mobile crushers and screening plants. In the past 12 months, I've sent back about one in ten first deliveries to be corrected: wrong configuration, missing documentation, or a spec that didn't match the purchase order.

Over four years of doing this, I've heard the same questions from operators, quarry owners, and prospective dealers. Here are the ones worth answering.

1. What do Kleemann model numbers like MC 110 or MR 130 actually mean?

They're not random. They tell you what the machine is and the approximate size of the crusher inlet.

MC means mobile jaw crusher. MR is a mobile impact crusher. MCO is a mobile cone crusher. MS stands for mobile screen. The number—110, 130, 90—refers to the crusher inlet size in millimeters. The MC 110(i) EVO2 has a jaw crusher inlet of around 1,100 x 700 mm. The MR 130(i) EVO2 carries a 1,300 x 900 mm impact crusher inlet.

The letters after the size matter too. The "i" and EVO2 suffixes indicate the generation and feature level, and they affect everything from pricing to parts compatibility. PRO is Kleemann's premium line for tougher applications. Always match the full model code, not just the numbers, when you compare quotes. I've seen purchase orders where the buyer assumed the EVO generation was included. It wasn't.

2. Which crusher specifications matter most?

It's tempting to think the two numbers on the model name tell you everything. They don't. When I review a Kleemann crusher spec sheet, these are the categories I focus on:

• Feed opening and max feed edge — the practical size of rock the crusher can accept without pre-processing.
• Output capacity — usually stated in tons per hour, but it's material-dependent. The same impact crusher might handle 400 t/h of limestone and only 280 t/h of granodiorite.
• Transport dimensions and weight — on a mobile plant, this decides whether you need special permits to move it.
• Engine power — not the whole story, but it tells you if the plant can run at full load without straining.
• Hopper and conveyor configuration — the stuff people forget until they're on site.

In one audit, I flagged a machine because the crusher setting range didn't match the application the customer described. The sales team had sold the right model—but with the wrong discharge conveyor setup. A 20-minute spec review caught it before it shipped.

(note to self: this is why we read the fine print at the bottom of the data sheet.)

3. Jaw crusher, impact crusher, or cone crusher—how do you choose?

Broadly:

• Jaw crushers are primary units. They handle big, hard rock and reduce it to a manageable size for downstream equipment.
• Impact crushers are the workhorses for medium-hard to soft rock. They produce a good cubical shape, which matters for concrete and asphalt production.
• Cone crushers are for secondary and tertiary crushing of harder, abrasive materials. They produce a finer, more consistent product.

That's the simple version. The less simple version: your specific rock type, feed size, product requirements, and moisture content all shift the answer. I can only speak to the machines I've inspected. If someone tells you "always pick an impact crusher" or "cones are better for everything," they're oversimplifying. When you're processing bulk rock in high volumes, the right choice comes from a material test and a cost-per-ton calculation—not a rule of thumb.

4. What should a distributor check before taking on a Kleemann line?

This is the rock crusher distributor buying guide part. It's not glamorous, but it saves everyone from a bad partnership.

First, demand. Who in your region is producing aggregates, recycling concrete, or crushing demolition material? Mobile crushers are premium equipment. If the local market is mostly small contractors doing occasional crushing, a used machine or rental fleet might make more sense for them—and that's an honest answer you should be prepared to give.

Second, parts. OEM parts for Kleemann machines run through the Wirtgen Group network. You need to know lead times for wear parts—jaw plates, impact bars, screen mesh—and have committed inventory for the fastest-moving items. A crusher sitting idle because a dealer didn't stock a $200 filter makes everyone look bad.

Third, service capability. These machines have sophisticated control systems. Your technicians need proper training and diagnostic software. When we onboarded two new distributors in 2024, the one that invested in a trained service lead before launch succeeded; the other planned to "learn as we go" and had unhappy customers by month six.

5. What quality checks should a buyer insist on before accepting a new crusher?

The factory inspection is good. It's not the same as verifying the machine you received is what you actually ordered.

A basic pre-acceptance checklist:

• Verify the model number, production year, and configuration against the purchase order.
• Check the hydraulic system for proper operation and leaks.
• Run the engine through a cold start and warm-up cycle. Listen for irregular noise.
• Test conveyors for tracking and speed alignment.
• Verify all safety systems: emergency stops, guards, lockout points, warning labels.
• Confirm documentation: CE declaration, test reports, warranty terms, maintenance plan.

I rejected a delivery this year because the serial number on the CE certificate didn't match the serial number on the machine frame. The vendor called it an administrative error. That's probably true. But it would have created a customs headache and a warranty dispute down the line. We fixed it before shipping. Zero drama.

6. How much should you trust horsepower and throughput numbers?

Use them as a guide, not a promise. The published throughput for a Kleemann crusher—for example, up to around 300 t/h for an MC 110(i) EVO2 in optimal conditions—assumes the right feed material, the right crusher setting, continuous feed, and proper maintenance.

Reality is messier. If your feed has recirculating loads, oversized pieces, or variable contamination, output drops. That's not a machine defect. It's a duty cycle issue. When we compare equipment for customers, we typically expect 70–90% of rated output in real operating conditions, depending on the application.

The question isn't "what's the peak number?" The question is "what does this machine produce at a consistent, sustainable cost per ton?"

7. What does total cost of ownership look like for a Kleemann crusher?

People think expensive machines deliver better quality. Actually, it's reversed: manufacturers who deliver consistent quality and reliable support can charge more. The price is a result, not a cause.

Total cost of ownership means: purchase price + transport and setup + fuel + wear parts + maintenance + administrative costs (permits, insurance, training) − resale value at the end. Wear parts are the line item that surprises people most. Impact crusher wear bars and jaw plates are consumables with a predictable cost per hour. I always ask for wear part cost per ton when reviewing bids. A machine that's 5% cheaper upfront but 15% more expensive in wear parts loses quickly.

Context matters more than the sticker price. We once ran two identical-model Kleemann crushers at different sites—one in a limestone quarry, one processing river gravel. The wear life difference was significant. Same machine, same brand, widely different operating costs.

8. How much does after-sales support matter, and what should you ask for?

It matters more than almost any spec on the sheet. A crusher down for three weeks costs more in lost production than most upgrades cost upfront.

Ask the dealer or manufacturer, in writing:

• What is the parts fill rate? What percentage of parts requests ship same-day or next-day?
• What are the lead times for wear parts and critical spares?
• Are service engineers available locally, or do they fly in?
• How long is the warranty, and what's covered on wear items?
• Is operator and maintenance training included?

To be fair, third-party parts are sometimes fine. I've seen aftermarket filters that tested well. But for crusher wear parts, metallurgy and heat treatment matter. A cheap jaw plate works—until it wears out in half the hours and you lose a day changing it. That's a false economy.
