Granulators play a crucial role in recycling, plastics, and waste processing industries, breaking down materials into smaller, manageable sizes. Over time, key components wear out due to constant impact and abrasion, leading to reduced efficiency and costly downtime. At JR Gilbert Engineering, we specialise in manufacturing high-quality granulator spare parts, helping businesses avoid long lead times from overseas suppliers by offering a fast, reliable, and UK-based alternative.

With over 40 years of experience in precision machining, we provide a full range of replacement parts, from consumable wear items to fully machined granulator components, ensuring maximum machine uptime and performance.

1. Hardox Wear Pads & Side Plates

Granulators are exposed to extreme wear and abrasion, requiring tough, impact-resistant materials. We supply Hardox wear pads, side plates, and clamping bars, extending the lifespan of your equipment and minimising downtime. Our components are precision-cut and machined to OEM specifications or can be custom-designed to meet your exact needs.

2. Precision Grinding For Large Granulator Blades

Sharp, well-maintained blades are essential for efficient granulation. At JR Gilbert Engineering, we have a large precision surface grinder (3200 x 1370mm) capable of regrinding worn granulator blades, restoring them to like-new sharpness and performance. This cost-effective solution reduces the need for frequent blade replacements and improves cutting efficiency.

3. Granulator Screens – Custom-Manufactured To Your Needs

Granulator screens control particle size and material flow, and when they wear out or become damaged, production can come to a halt. We manufacture custom replacement screens, ensuring the correct hole size, thickness, and material strength to optimise your granulation process. Our screens are made from high-strength steel to withstand heavy-duty usage.

4. Reverse Engineering For Hard-To-Source Components

Many granulator parts are imported, leading to long wait times and high costs. Our reverse engineering capabilities allow us to accurately reproduce worn or damaged components, providing a faster, cost-effective alternative to waiting for overseas shipments. Whether it’s shafts, rotor components, bearings, or structural parts, we can manufacture replacements to OEM or improved specifications.

5. CNC Machining & Fabrication For Granulator Parts

As a specialist in precision CNC machining, we manufacture a variety of granulator components, including:

Blade holders and rotor shafts
Housing and frame components
Feeder and discharge chute parts
Bolted wear liners and protective guards

Our in-house machining and fabrication ensure all parts are manufactured to strict quality standards, helping reduce maintenance costs and increase equipment lifespan.

6. Full Finishing Services – Ready-to-Install Components

We also offer a full range of finishing services to enhance durability and longevity, including:

Hardening & heat treatment – For extended wear resistance.
Powder coating & wet painting – To protect against corrosion and impact damage.
Zinc plating & galvanising – Ideal for high-moisture environments.
