In 2022, I sat through a capital review where we compared a mobile Kleemann crushing package against a fixed crushing plant proposal. I was not the final decision-maker. I was the person who had to make the purchase decision work after the engineers finished arguing. The finance director at the time wanted one number: initial equipment price. That one number caused us to make the wrong decision.

I’m not saying the fixed plant was a bad machine. I’m saying we chose it for the wrong reason. The fixed plant’s price looked better before installation. After concrete, steelwork, electrical work, permits, and a few surprises, our total project cost was higher than the mobile package would have been—and we had an asset that could not leave the site.

If you put the spec sheets side by side, a fixed plant and a mobile Kleemann plant can look similar before you account for site logistics. Fixed crushing installations are usually chosen for a site life of many years, where foundations and conveyors can be spread over large volumes. Mobile tracked equipment, such as Kleemann MOBICAT jaw crushers and MOBIREX impact crushers, is a different kind of asset. It can be redeployed when the ground changes. That matters more than the brochure number.

What This Comparison Actually Covers

The mistake people make when comparing Kleemann mobile equipment with fixed crushing is that they compare only the machines. This is like comparing a lease with a mortgage by looking at the monthly payment alone. The useful comparison has four parts: capital exposure, site flexibility, running cost assumptions, and after-sales support. Every project will have a different weight, but these are the dimensions that change decisions.

Comparison 1: The Initial Price Divide Is Usually a False Divide

The fixed plant proposal in our case was less expensive on equipment alone. But when we added the cost of making the site ready, the price advantage began to disappear. A fixed crushing line needs foundations, often a steel support structure, electrical connections, access roads, and sometimes permits that require months before the first rock passes through.

Mobile Kleemann equipment avoids much of that site preparation. The MOBICAT MC 110i EVO2 jaw crusher arrives on tracks and can be set up on a stable working area. The machine isn’t magic. It still needs a utility connection, fuel, and a place to stockpile material. But it does not need a concrete pad built for the next thirty years just to test a five-year supply.

The decision here is not about brand loyalty. It is about time horizon. If the site life is long and utilization is high, fixed crushing can win. If the site life is uncertain, the fixed option carries more risk than the price list suggests.

Comparison 2: Flexibility When the Ground Changes

This is the dimension that convinced me. Our first crushing location was always meant to be temporary, but the accounting still treated the fixed plant as a long-term asset. When the permit renewal was delayed, the projected tonnes did not happen. The fixed plant sat idle while we paid for the earthworks that surrounded it.

A mobile Kleemann spread can be moved to another face, another contract, or another site. This sounds obvious. In practice, it changes the financial conversation. A mobile crusher is still a resaleable asset; a custom fixed plant is more likely to stay with the ground it was built on.

To be fair, relocating a mobile plant is not cheap. There are transport permits and setup costs, and the plant must be commissioned again. But it is possible, and that possibility has a real option value when the market changes unexpectedly.

Comparison 3: Running Cost and the Utilization Trap

I used to believe fixed plants were cheaper per tonne to run. Some are. But many of the operating cost calculations assume high utilization from day one. In practice, new sites have slow ramping, weather stoppages, permit delays, and sales cycle gaps.

The hourly operating cost of a mobile Kleemann unit includes more hydraulics, more drives, and more daily maintenance than a fixed motor-driven line. I’m not going to argue otherwise. But a lower operating cost is only an advantage if the machine is running enough hours to cover its fixed overhead.

If you run 4,000 hours a year for 20 years, stationary has an edge. If you run 2,500 hours for the first two years, mobile equipment gives you the ability to reschedule and relocate. This is the part that felt uncomfortable to finance: the best machine on paper is not always the best machine for the actual calendar.

Comparison 4: Screening Flexibility and Parts Support

In the aggregate business, crushing is only half the story. Screening is where the product is made and where payment is decided. A permanent plant can be designed with tall screens, multiple conveyors, and large stockpile systems. That remains a real advantage at a site that will not move for decades.

A Kleemann MOBISCREEN unit placed after the crusher is easier to rearrange when the product specification changes. If the customer changes aggregate sizes, you change screen media and settings. You do not have to redesign a long line of connected conveyors.

Parts support is harder to compare because it is regional. As of the end of 2024, our local dealer gave us shorter lead times for common Kleemann wear parts than for components on the ageing fixed plant we were comparing. That may not be true everywhere. Check the dealer’s parts stock before signing anything. If you operate far from a support location, whichever option has the shortest lead time for wear parts is often the real winner.

What I Would Recommend in 2025

If I were choosing for a long-life quarry with proven material, good access, and committed sales, I would seriously consider stationary or semi-stationary crushing. In that situation, a mobile Kleemann plant may still work, but it may not be the lowest total cost.

If I were choosing for a shorter permit, a contract crushing job, or a project where demand is uncertain, I would choose mobile equipment. I would rather have a Kleemann jaw or impact crusher that can be moved or sold than own a concrete foundation that cannot.

Here is the rule of thumb I use now:

If the site life is under seven years, do not build a monument. Build a moveable production line.

Kleemann has a strong reputation in this segment, and for our purposes the EVO2 technology made sense. But no brand decision is complete without dealer support, parts availability, and a realistic operating schedule. Identify the constraint that is most likely to change during the project, then compare the options around that constraint. If you do that, the comparison becomes much easier to explain to finance—and much easier to live with after the concrete is poured.

Pricing and regional support details change quickly. I wrote this in February 2025, so the general logic is durable, but current quotes and service agreements should be verified before you commit.
