Nordberg Cone Crusher Buyer’s Guide: HP, GP & MP Series – Which Specs Actually Matter for Your Operation?

So you're looking at Nordberg crushers – but which series fits your specific setup?

I'm not a process engineer, so I won't pretend to tell you exactly how to design your entire crushing circuit. But as someone who has sourced replacement parts and new equipment for mine sites and quarries over the last 5 years, I've learned one thing: there is no single "best" Nordberg model. The HP, GP, and MP series solve very different problems. And if you're just comparing spec sheets, you might miss the nuance.

Here’s what I’ve found after ordering dozens of units and managing inventory across multiple sites. Let's break it down by the three main real-world scenarios I see.

Scenario 1: You need maximum tonnage in a secondary or pebble crushing role

This is the HP800e / HP900e territory. If your key search term is something like "Nordberg HP800e capacity MTPH", you're probably in a high-tonnage copper or gold operation where you need consistent throughput in the 500-800+ mtph range.

From the outside, it looks like horsepower is horsepower. But the reality is that the HP series' tramp release system and the way it handles fines can make or break your liner life. In my experience, the HP800e with the right eccentric throw setting (3/8” vs 1/2”) can push an extra 10-15% volume in a secondary duty, if your feed gradation is stable.

A caveat: I don't have hard data on industry-wide failure rates for HP800e hydraulics, but I’ve seen three issues with accumulation tanks across different sites. It's not a deal-breaker—but budget for an extra accumulator if you're running it hard. That advice saved one of our clients a costly unplanned shutdown.

For replacement parts, don't assume OEM vs. aftermarket is a simple choice. The idea that 'OEM always lasts longer' ignores the fact that some aftermarket bowls on the HP300 are now made with profiles that actually improve wear life in high-silica feeds. Just vet your supplier's quality control process.

Scenario 2: You're balancing flexibility and cost in a tertiary or gravel application

Look at the GP series (like the GP550). This is actually where I see a lot of operators make a mistake—they buy an HP when they could get the same product with less horsepower and a lower parts cost from a GP.

Why? Because the GP crusher is a more modern, simpler design for fine crushing. If your goal is to produce cubical aggregate for asphalt or concrete, the GP's stroke and speed combination is often superior. I've seen a GP220 outperform a smaller HP in terms of particle shape, even if the raw tonnage was a bit lower.

It's tempting to think you just need the highest horsepower number. But a 300 hp GP550 will give you a finer product in a tight circuit than a 400 hp HP400 in certain feed conditions. That's because the GP's chamber geometry is optimized for inter-particle crushing.

People assume the lowest quote means the vendor is more efficient. What they don't see is the long-term cost: GP mainframe liners are cheaper than HP mainframe liners, but the GP's pinion and gear sets can be more sensitive to misalignment. When you're budgeting for consumables, factor in gear inspections every 500 hours.

Scenario 3: You have high-power demands in a primary or secondary underground application

The MP series (like the MP800) is your machine. This isn't really a debate. If you need to push 800+ horsepower into a machine in a confined space (like an underground mine), the MP is built for it. The MP800 is essentially a brute-force crusher.

From the outside, the MP800 looks like just a bigger HP. The reality is that the MP's head and shaft assembly is substantially heavier to handle the higher crushing forces. If you're sourcing replacement parts, pay attention to the bushings—the MP800 uses a different bronze alloy than the HP series. I've seen one site burn a bushing because they ordered an HP800 bushing for an MP800 and it couldn't handle the load.

This gets into metallurgy territory, which isn't my expertise. I'd recommend consulting your application engineer before mixing and matching components. What I can tell you from a procurement perspective: verifying the hardness specs (Rockwell C) on replacement liners is worth the extra 15 minutes. Don't just check the weight match.

How to diagnose which scenario you're in

Here’s a quick checklist to narrow it down:

• Your primary goal is raw tonnage > 500 mtph in a medium to coarse secondary role? → HP800e / HP900e. Budget for hydraulic accumulators and monitor fines content.
• You need cubical product in a tertiary/quaternary role, and power is a constraint? → GP series. Lower initial parts cost, but more attention needed on gear alignment.
• You're in a high-power underground application with 600+ mtph required? → MP series (MP800). Expect higher initial investment in bronze bushings, but longer component life under heavy loads.

If you're still unsure, start with the feed gradation. If 70% of your feed is under 100mm, the GP series will usually give you a better result than the HP. If the feed is coarser or you are crushing ROM material (run-of-mine), the HP or MP is your answer. It’s a simplification, but it's a strong starting point—much better than just comparing spec sheet horsepower figures.

Pricing as of early 2025: expect a new HP800e to be in the range of $400,000 to $550,000 USD depending on options, but verify current pricing with your local distributor.
