How to Compare Drilling and Crushing Equipment Quotes: A Buyer's Five-Step Checklist

I run office purchasing for a mid-sized aggregate and construction materials company in northern Europe—about 140 employees and three active sites. I'm not a mining engineer. But since 2020, I've been the person who collects quotations, checks specification sheets, and makes sure the paperwork side of an equipment purchase doesn't fall apart. That seat teaches you where buying decisions actually go wrong.

This checklist is for anyone sitting in the same chair. If your operations team asks you to review drilling rig specifications, rock drill specifications, or crusher compliance requirements before an equipment purchase, these five steps are the order I follow.

They won't pick the machine for you. They will keep a proposal that doesn't fit from ever reaching the finance approval stage. There are five steps, and on our last mobile crusher purchase in 2025, running them in order took about two working days.

Step 1: Write your site conditions down before you ask for quotes

Most spec-sheet mistakes start before the spec sheet arrives. If you email three manufacturers a blank "we need a drill rig" request, you'll get three different machines built for three different jobs. That's on the buyer, not the sales team.

I learned this the hard way in 2024, when we started looking for a new surface drill rig. The first round of quotes was impossible to compare. One vendor assumed a 12-meter bench. Another assumed 6 meters. One included a high-pressure compressor in the base package; another listed it as an option; a third was configured with a different rod length. None of those vendors did anything wrong. We simply hadn't told them what a typical shift looks like for us.

Now I write a one-page brief before contacting anyone. For a drilling rig, the brief includes:

• bench height and the hole diameter you actually drill—for us, that's 9–10 m benches and 115 mm holes;
• target meters per shift, not just a vague production goal;
• rock type, because hard granite and abrasive limestone change everything;
• site constraints like steep ramp access, noise limits, or water supply for dust control.

For a crusher, the brief needs the feed size, the product sizes you sell, target tonnes per hour, and whether the plant will sit in a fixed quarry position or move between construction jobs. A mobile cone crusher that spends its life on highway projects needs a different configured package than one parked at a stationary feed setup.

Checkpoint: before sending an RFQ, if a vendor would have to ask "what rock and what hole size?" the brief is not finished.

Step 2: Put crusher compliance requirements into the RFQ early

This is the step I used to skip, and it's the expensive one to skip.

In the EU, new drill rigs and crushers need machinery safety documentation—currently a CE declaration of conformity under the Machinery Directive 2006/42/EC. That directive is on its way out: the Machinery Regulation (EU) 2023/1230 starts applying on 20 January 2027, so verify the current status at official EU sources if you're reading this later. Diesel-powered mobile equipment adds another layer: emissions compliance under the Stage V rules of Regulation (EU) 2016/1628, or the U.S. EPA Tier 4 equivalent if the machine is headed to North America (see epa.gov).

I group all of this under crusher compliance requirements, but the same thinking applies to drill rigs. A machine can be technically excellent and still sit idle for weeks if the declaration of conformity lists the wrong serial number, or if the guard modifications required by local inspectorates were never documented.

During our 2025 mobile crusher evaluation, one quotation had "CE" printed on the brochure, but when I asked for the declaration, the dealer sent a scanned document for a different machine serial number. That quote was cut. The machine might have been perfectly good. But we couldn't take that risk on a six-figure purchase.

Checkpoint: a quote without a current declaration of conformity and a list of applicable standards is not a quote. It's a placeholder.

Step 3: Compare the operating point, not just the maximum numbers

Machine brochures love maximums: maximum hole diameter, maximum torque, maximum throughput. But a machine doesn't work at its maximums all day, and it can't deliver all of its maximums at the same time.

When you're comparing drilling rig specifications, look at how the whole package behaves together. The rig may list a hole diameter range up to 152 mm, but production also depends on the feed length, the compressor package, and the rock drill's percussion power and rotation torque at your operating pressure. Ask each vendor one direct question: at our hole size and our bench height, with the exact package you're quoting, what is the expected output per shift? Put the answers side by side.

The same logic applies to rock drill specifications. A rock drill's impact power is quoted at a certain operating pressure and with a certain flushing air supply. If the carrier's compressor is undersized, the drill won't reach that number in dusty, deep holes.

Crushers are even worse for this. Capacity figures on crusher spec sheets usually assume medium-hard rock and a specific closed-side setting. If your site runs wet, sticky material, or you need a tighter product size, the real throughput drops—sometimes a lot. In our 2025 comparison, the plant with the highest brochure tonnage dropped the most when we recalculated at the product sizes we actually sell. It fell out of the final two.

Checkpoint: every number in your comparison sheet should be labeled "at our site conditions," not "from the brochure."

Step 4: Separate standard equipment from optional extras before comparing prices

The biggest price differences between competing quotes are often not in the base machine. They're in what the salesperson included—or left out—of the configuration.

A mobile crusher can be quoted with or without a magnetic separator, dust suppression, hopper extensions, extra service platforms, remote monitoring hardware, and a dozen smaller items. Each of those costs real money.

In the three quotes we collected for mobile cone crushers in summer 2025, optional extras added roughly 15–25% to the base price, depending on the manufacturer. I don't have industry-wide data on this; I only have our RFQ set. And pricing changes fast, so treat that range as an illustration, not a fact.

What is optional for one manufacturer can be standard for another. A lower base price can simply mean more exclusions. The fix is boring but effective: build your own comparison matrix with one row for each feature and three columns—standard, optional, not available. When we did this in 2025, it cut our evaluation time noticeably. More importantly, it stopped us from comparing apples to pricing structures.

Checkpoint: if two quotes don't have the same list of included items, the price comparison is meaningless.

Step 5: Model the five-year cost before you sign anything

The purchase order price is only the starting point. After our shortlist was down to two machines, I built a simple five-year cost table with these lines:

• configured purchase price;
• freight, commissioning, and operator training;
• scheduled maintenance and service costs;
• wear parts—drill bits, rods, and crusher liners;
• energy or fuel per operating hour;
• expected value at the end of year five.

This is where the low-price machine often loses. A few years earlier, we picked a screening plant because it was about 7% cheaper than the nearest alternative. The base price didn't include commissioning support, and our crew lost roughly a week trying to sort out the setup. By the time we paid a local contractor to fix it, the discount had disappeared.

When we applied this five-year view to the 2024 drill rig purchase, the decision came down to two manufacturers. We went with the Sandvik rig, not because of the logo, but because the configured package matched our site brief, the compliance documents were complete, and the genuine parts availability was clearly laid out. The checklist made that easy to see.

Checkpoint: the cheapest machine is only cheap if it still looks cheap after you add commissioning, wear parts, maintenance, and expected downtime.

Final caveats

This checklist is not a substitute for engineering review. I still send the two finalists to an independent consultant before we sign. What the checklist does is get you to that point faster and with fewer surprises.

Regulations also change. The compliance statements in this article were accurate as of May 2026, but machinery rules and emissions requirements evolve. Verify current requirements at the official sources for the country where the machine will operate.

And yes, the same process applies no matter whose name is on the brochure. That includes Sandvik mining equipment, the track-mounted crushing and screening units often described as Sandvik construction equipment, or any other major manufacturer. Ask for the same documents, make them confirm the operating point, and compare the same configured package. The logo doesn't change the due diligence.
