I’ll say it in a way that makes our plant manager roll his eyes: don’t buy a Kleemann Mobiscreen because of the number on the sales sheet. Buy it because of everything that happens after the machine starts working. The first part has never been our problem. The second part is where vendors win or lose.

I’m the office administrator for a 140-person aggregates company. I process purchase orders for equipment, parts, and service—roughly $2.4 million a year across eight vendors. I report to operations and finance, which means I see both sides of every equipment decision. Production wants output. Accounting wants clean invoices. I want a process that doesn’t fall apart on a Tuesday morning.

Why I Stopped Buying on Spec Sheets

The conventional wisdom in this business is that you compare the machine specs, you get the best price, and you trust the warranty. After five years of watching equipment purchases, I think that’s backwards. Specs show the machine’s ceiling. The after-sales process defines how close you get to that ceiling.

In 2022 I approved a purchase from a vendor because the price was attractive and the throughput looked fine. The machine itself was not a disaster. It was everything around it that hurt. Invoices arrived without PO numbers, our accounting team spent hours chasing them down, and a wearing part that should have been a normal stock item took nine days to arrive. Nine days. In our world that’s more than overtime. It’s lost production and a lot of unhappy phone calls.

Since then, I evaluate vendors the way I evaluate suppliers in any other category: process, response time, and whether they can prove they have a service system. Price still matters. It’s just not allowed to skip ahead of reliability.

The Peregrine vs Hawk Comparison

Let me explain what I call the peregrine vs hawk problem. A peregrine is famous for one thing: speed. In a dive, nothing beats it. But a quarry has more than one dive per day. A hawk does not have the same dramatic record, but it can patrol for hours and handle irregular conditions. When I look at equipment, I ask whether we’re buying a peregrine moment or a hawk season.

That comparison is not a knock on the competition. Some of the machines we looked at are genuinely fast and clever. The problem is that they act like peregrines: impressive burst, but everything has to be perfect for that burst to happen. The Kleemann Mobiscreen we ended up buying is more like the hawk. It’s built for daily hunting, not a highlight reel. You set it up, you run it, you keep the process simple.

The Peanut Butter Standard

This next one sounds silly, but it’s the real test I use. I call it the peanut butter standard. Peanut butter is not the star of the lunch. It is the binder that keeps the rest of the ingredients in place. If you spread it evenly, the sandwich survives the drive. If you skip it, everything falls to the bottom of the bag.

In a crushing circuit, the hopper or crusher is usually treated as the star. The screen is treated as a helper. That’s wrong. The screen is the peanut butter of the site. It determines whether material moves at a steady pace or piles up in a mess. A Kleemann Mobiscreen earned our order because it treats that binding role as a priority. The screen box, drive, feeding system, and control logic are designed to work as one flow instead of separate boxes bolted together.

I’m not an engineer, but the EVO2 generation made sense to me at the process level: fewer surprises, easier setup, more predictable operation. To me, predictable operation is the whole point.

Kleemann Service Center Photos: What I Asked For

During our evaluation, I asked every candidate vendor for photos of the service center that would support us. Specifically, I wanted Kleemann service center photos before we signed the order. Not because I wanted to see clean floors. I wanted to see if the service center was designed like a process.

The Kleemann service center photos we received showed work bays with enough room to move around a tracked machine, organized tool boards, labeled parts shelving, and a wash bay that didn’t look like a flood zone. Honestly, that impressed me more than the capacity chart. A messy workshop is a forecast. If the shop cannot manage its own space, it won’t manage your repair diagnosis either.

I also checked the quality standards behind the process. The manufacturer’s official disclosures describe ISO 9001-based quality management in the production environment. Again, that doesn’t mean every part is perfect. It means there is a documented loop when something is not perfect. I can work with that.

The Cost Objection

Now for the obvious objection. A Kleemann is not the lowest-priced option in every comparison. I’m not going to pretend it is. If you only compare line one on the purchase order, you can buy cheaper and feel good for about three months.

The total cost spread includes downtime, the time we spend chasing service trucks, and the accounting hours spent reconciling invoices. I know those costs because they are in our internal system. Our service records from the first season of use showed fewer delay codes than the prior machine. That is a sample size of one, but it is the sample size that pays my salary.

I am not saying fixed plants are wrong. For a 20-year deposit, a fixed plant can be the most efficient answer. What I am saying is that mobile equipment deserves the same operational discipline. Kleemann’s mobile screening line is not Plan B for mining. It is a purpose-built tool, and the tool only works if the support around it also works.

My Bottom Line

If I had to sum up my position, it’s this: use the peregrine vs hawk comparison to decide what speed you actually need, apply the peanut butter standard to the flow, and ask to see Kleemann service center photos before you sign. The machine specs matter. The process behind the machine matters more.

Our decision was a Kleemann Mobiscreen. But more importantly, the decision was based on a system I can trust.
