Harder Isn't Always Better

One of the biggest misconceptions in blow bar selection is that the hardest material will always deliver the best performance.

In reality, every blow bar specification is a balance between:

🔹 Hardness (abrasion resistance)
🔹 Toughness (impact resistance)

A high-chrome blow bar may excel in a clean, abrasive quarry application.

The same blow bar may crack prematurely in a recycling application where tramp metal and contamination are common.

The best-performing blow bar isn't necessarily the hardest. It's the one that matches the application.

Excessive Wear Is Usually Telling You Something

All blow bars wear.

The question is whether they're wearing at the expected rate.

Here are three common causes of excessive wear:

• Incorrect metallurgy for the material being processed
• Excessive rotor speed
• Running with inadequate material in the chamber

For highly abrasive materials such as granite, basalt, quartzite, and reclaimed asphalt pavement, choosing the wrong blow bar grade can dramatically reduce service life.

Often, the solution is not changing the machine, but changing the specification.

Why Do Blow Bars Crack?

Cracking is one of the most serious blow bar failure modes because once a crack starts, it can quickly develop into a complete fracture.

Common causes include:

• Using high-chrome blow bars in high-impact primary applications
• Tramp metal entering the crushing chamber
• Oversized feed material
• Thermal shock from insufficient warm-up time

High chrome materials deliver excellent abrasion resistance, but they are less tolerant of heavy impact loads than tougher martensitic alternatives.

The right metallurgy depends on the application.

Happy Labor Day! 🎉

Today we're recognising the workers, operators and crews whose hard work keeps projects moving every day. 🔧

Maintenance Minute — Day 10/10: Start with Quality Parts

Correctly specified wear parts wear predictably and protect the components behind them for their full designed life. Over a year, the cost gap between a reliable part and a cheaper one that wears unevenly or fails early rarely favours the cheaper option. Longevity starts with what you put into the machine.

Maintenance Minute — Day 9/10: Train Operators to Catch Early Warning Signs

Unusual noise, a shift in product shape, visible vibration: these are the earliest signals a crusher gives before something fails. Operators who know what normal sounds and behaviour look like can catch problems long before they show up on an inspection report. Structured training turns your team into your first line of defence.

Maintenance Minute — Day 8/10: Match Parts to the Application

Not all manganese liners or bearing assemblies are built the same, and the wrong specification for your material wears faster no matter how well the machine is maintained. A primary crusher on coarse feed needs a different profile and grade than a tertiary stage producing fine aggregate. Spec to the application, not just the machine model.

Maintenance Minute — Day 7/10: Let the Data Tell You Something's Wrong

Power draw, oil pressure, oil temperature, throughput: your crusher is reporting on its own condition in real time. High power draw with lower throughput usually means the CSS has drifted or the liner profile's worn past its efficient range. Know your normal operating ranges, and treat any deviation as a prompt to investigate.

Maintenance Minute — Day 6/10: Don't Skip the Lubrication Programme

A blocked filter or degraded oil can take out a main shaft bearing in minutes, and that failure cascades straight into the eccentric, countershaft, and pinion gear. Check oil condition against temperature and contamination thresholds, replace filters on schedule, and let oil reach operating temperature before running under load. Cheap insurance against an expensive repair.

Maintenance Minute — Day 5/10: Set and Hold the Correct CSS

Run your closed side setting too tight and the crusher pancakes material instead of fracturing it cleanly, bouncing the mainframe and loading up the locking mechanism and bowl seat. It's a progressive problem: once it starts, it accelerates across multiple parts at once. Set it to spec, then adjust as liners wear.
