Kleemann MR 130 Specs & Crusher OEM Parts: A Practical Rock Crusher Specification Guide

Start Here: The MR 130 Spec That Matters Most

If you're renting, buying, or dispatching a Kleemann MR 130 for a deadline, don't start with the tonnage number. Start with the feed opening, the max feed size, the CSS range, and the transport weight. The MR 130 EVO2's 1,300 x 900 mm crusher inlet is usually the number that decides whether your excavator, your shot rock, and your haul route actually fit the job. Capacity is the result you get after those four things line up—not a promise you can quote to a client.

I coordinate mobile crushing and screening mobilizations for a mid-size contractor. I've handled 60+ rush orders in nine years, including same-day turnarounds for roadbase and recycling clients. In March 2024, a client called 36 hours before a demo needing a mobile impact crusher for a 0-31.5 mm roadbase sample. Normal turnaround was 10 days. We found an MR 130 EVO2 with the right OEM blow bars, paid $2,800 in express freight on top of the normal mobilization cost, and delivered with four hours to spare. The client's alternative was canceling the demo and losing the $40,000 contract. That's the lens I use for every Kleemann crusher spec: what breaks the deadline first?

What the Kleemann MR 130 Specs Actually Tell You

Per Kleemann's published MR 130 EVO2 specification sheet (accessed May 2026), the machine is built around a 1,300 x 900 mm impact crusher inlet, with a maximum feed size around 900 mm depending on material shape and model year. Kleemann lists capacity up to 450 t/h under ideal conditions, engine power around 353 kW, and operating weight in the 54,000 kg class. Those are headline numbers. Here's how I read them on a real job. Verify current specs at kleemann.info or through your dealer before quoting a contract.

Feed opening and max feed size

The 1,300 x 900 mm inlet sounds generous until you're feeding slabby limestone or recycled concrete with rebar. A rock that fits the opening on paper can still bridge if it's long and flat. I ask for the quarry's shot curve and the excavator bucket width before I trust any rock crusher specification guide. If the feed is slabby, you may need a prescreen or a different crusher type. The MR 130 is an impact crusher, so it likes material that breaks rather than material that needs slow compression.

CSS and product gradation

The closed-side setting—or apron gap on an impactor—controls the output curve more than most buyers expect. Want more fines? Tighten it. Want higher throughput? Open it, but accept a coarser product. The MR 130 can produce a range of roadbase and aggregate specs, but you can't hit every gradation at maximum tonnage. That's the trade-off.

Capacity: read the asterisk

Capacity is up to 450 t/h. Put another way: that's the best-case number with an ideal feed, the right CSS, no bottlenecks, and a loader that can keep up. In mixed demolition debris, I've seen an MR 130 run closer to 250-300 t/h and still be the right machine. If your project pays by the ton, undersizing the loader or overpromising the spec sheet will cost more than the crusher itself.

Power, weight, and transport

The engine is only useful if the whole plant moves. Check transport length, width, height, and weight against local permits. A 54,000 kg class machine doesn't sneak onto a standard lowboy without planning. For rush jobs, permitting and transport are often the real critical path—not the crusher.

How to Read a Rock Crusher Specification Guide Without Getting Fooled

It's tempting to think you can compare mobile crushers by lining up horsepower and tonnage. But identical specs from different vendors can produce wildly different results once you add feed shape, moisture, silica content, and recirculation. The 'bigger is better' advice ignores transport limits, site layout, and the cost of downtime.

Here's the checklist I use when a client sends a spec sheet and asks if it's enough:

• Feed curve, not just max size. Ask for the actual gradation. A 900 mm max feed size means little if 30% of the feed is already fines that should bypass the crusher.
• Bulk density and moisture. Wet, sticky material can cut throughput and clog a screen deck. A machine that shines in dry granite may struggle in clay-heavy fill.
• Abrasiveness and silica. High-silica rock eats blow bars. That's where crusher OEM parts and wear planning become a production decision, not a purchasing detail.
• Recirculation and screening. If you need a tight spec, a closed-loop setup with a screen may matter more than the crusher's raw capacity.
• Setup time. Some plants fold out in 15 minutes. Others need more crane work. On a rush job, setup time is throughput.
• OEM parts lead time. A great crusher with a two-week wait for blow bars is a paperweight on day three.

To be fair, not every job needs a full technical review. If you're crushing dry limestone to a loose roadbase spec, the MR 130 is probably going to do what you expect. The problems show up when the material changes or the deadline shrinks.

Crusher OEM Parts: The Emergency Variable

I've tested both OEM and aftermarket wear parts on our fleet. Some aftermarket options work fine for low-risk, long-run jobs. But on a rush Kleemann crusher mobilization, OEM parts are usually the risk-reduction choice, not a luxury. The fit is known, the wear profile is documented, and the dealer can trace the part by serial number. That matters when you're ordering at 4:30 p.m. on a Friday.

Switching to serial-number-based OEM parts ordering cut our wrong-part returns from roughly 12% to under 3% over two years. The automated process eliminated most of the 'I think this is the right blow bar' guesswork. That's the digital efficiency argument in practice: fewer manual checks, fewer errors, faster turnaround. It doesn't replace a good parts person—it just makes their job less frantic.

If a deadline is tight, the cheapest wear part is rarely the lowest total cost. One wrong blow bar can cost a day of production and a penalty clause.

When you're evaluating crusher OEM support, ask three questions: Can the dealer look up parts by machine serial number? What's the typical lead time for blow bars, aprons, and screen media? And is there emergency freight available? If the answers are vague, the spec sheet doesn't matter much.

A Five-Minute Triage for a Rush Mobile Crusher Job

When I'm triaging a rush order involving a Kleemann MR 130 or any mobile impact crusher, I work in this order:

1. Feed fit. Confirm max feed size, bucket width, and material shape. I knew I should verify the inlet against our excavator bucket on one job, but thought 'what are the odds?' The odds caught me when a 900-mm slab bridged the inlet and cost us two hours.
2. Product spec. Get the target gradation and tonnage. Then compare it to the CSS range and screen setup.
3. Transport. Check weight, dimensions, route permits, and site access. A machine that can't reach the pit isn't a machine.
4. Parts kit. Confirm OEM blow bars, aprons, and any critical wear items are on the truck or at the dealer.
5. Buffer. Add 24 hours if the material is unknown. Add 48 if permits are involved. The buffer is not padding; it's risk control.

When This Advice Doesn't Apply

The MR 130 isn't the right answer for every rock crusher job. If your feed is highly abrasive, very hard, or needs a tight cubical spec at high volume, a cone or jaw may be a better primary stage. If your site is tiny, a smaller impactor or skid-mounted unit may move faster. If you have months of lead time and a fixed location, a stationary plant might beat any mobile unit on cost per ton.

Also, specs change. Model year, engine option, screening attachment, and regional configuration all affect the numbers. Verify current Kleemann MR 130 specs with a dealer or the official Kleemann source before you put them in a contract. I think the machine is proven—but the paperwork is what saves you when the schedule slips.

The rush jobs that go well aren't the ones with the bravest promises. They're the ones where someone checked the inlet, the CSS, the transport weight, and the OEM parts list before the lowboy rolled. That's the whole rock crusher specification guide in one sentence: match the material, the product, and the support—then let the tonnage follow.
