Top 5 Most Commonly Replaced Pronar Parts – and How to Spot When You Need Them

Pronar machines are trusted across the waste, recycling and forestry sectors for their durability, performance, and efficiency. However, even the most robust equipment requires maintenance, and certain parts will naturally wear down over time.

Keeping on top of Pronar parts replacement is key to preventing costly downtime, ensuring safety, and extending the lifespan of your equipment. At CRJ Services, we stock a wide range of genuine Pronar spare parts, available for fast delivery across the UK and Ireland.

In this blog, we’ll look at the five most commonly replaced Pronar parts, why they wear out, and the warning signs that it’s time for a replacement.

1. Pronar Drum Screens

Why they wear out:

Drum screens are at the heart of Pronar trommel screeners, working continuously to separate materials. With constant contact against abrasive and heavy waste streams, it’s no surprise that drum screens eventually show signs of wear.

When to replace:

As a drum screen wears, you may notice reduced screening efficiency and an uneven material flow through the machine. Over time, cracks or thinning patches may also appear, which can seriously impact performance.

2. Pronar Conveyor Belts

Why they wear out:

Conveyors are constantly moving heavy and abrasive material. Over time, belts suffer from stretching, fraying, or damage caused by spillage and misalignment.

When to replace:

• Slipping or loss of tension

• Frayed or torn edges

• Frequent stoppages or breakdowns

3. Pronar Bearings and Rollers

Why they wear out:

Bearings and rollers are exposed to high loads, dust, and vibration. Without timely replacement, these small components can cause serious damage to other machine parts.

When to replace:

Excessive noise and vibration during operation are the first warning signs that bearings or rollers are failing. Misalignment and visible cracks are also strong indicators that replacement is due.

4. Pronar Hydraulic Hoses and Fittings

Why they wear out:

Hydraulic hoses are under constant pressure, handling extreme workloads day after day. Over time, exposure to the elements and repeated bending causes wear and deterioration.

When to replace:

Leaks or drips of hydraulic fluid are the clearest sign a hose is failing. You may also experience a noticeable loss of power or reduced machine efficiency when hoses and fittings begin to degrade.

5. Pronar Brushes

Why they wear out:

Pronar trommel screens are fitted with cleaning brushes that prevent material from clogging or sticking to the drum. These brushes are in constant contact with the screen surface, which means they gradually wear down through friction and heavy-duty use.

When to replace:

As brushes begin to wear, you may notice reduced cleaning efficiency, which can lead to blockages and reduced screening performance. Worn brushes can also leave behind material deposits that impact throughput.
