Not every blending application fits a standard catalogue part. When one of our clients needed a replacement shaft and ribbon assembly for their 1000-litre ribbon blender, the existing OEM supplier was no longer able to deliver — and generic alternatives weren't going to meet their production requirements.
They came to us. We engineered it from spec.
When an off-the-shelf part won't do, we build exactly what's needed.
The Brief
The client provided their original blender dimensions and performance requirements. The goal was straightforward: produce a direct replacement shaft and ribbon assembly that would fit their existing trough and drive arrangement, match original blending performance, and outlast the part it was replacing.
There was no room for approximation. Ribbon pitch, flight height, shaft diameter, end hub configuration, and overall assembly balance all had to be right — or it simply wouldn't work.
What We Produced
The finished assembly is a full double-helical ribbon and shaft unit built to the client's exact dimensional specification, including:
- Central shaft — precision-machined to suit the existing bearing and seal housings, with no modifications required to the blender frame.
- Inner and outer ribbon flights — formed and welded to the correct helix pitch for the 1000L trough length, ensuring proper counter-directional material flow
- Ribbon support spiders — fully welded to shaft and ribbons, positioned to match original spacing and load distribution
- End hubs and flanges — machined to match the existing drive coupling and tail-end bearing arrangement
The entire assembly was fabricated in stainless steel, finished and inspected before dispatch.
Why Custom Fabrication Made Sense
For a machine this size, getting the ribbon geometry wrong means poor blend quality at best and mechanical failure at worst. A 1000-litre blender running an ill-fitting assembly puts unnecessary load on bearings, seals, and the drive — shortening the life of components that are expensive to replace.
By working from the client's original specifications and building the assembly to suit their exact machine, we eliminated that risk entirely. The result was a drop-in replacement that restored full blending performance without any modification to the host machine.
Our Capability
This project is a good example of what we do regularly — taking a client's technical requirement and delivering a fabricated solution that meets it precisely.
If you're running process equipment that needs a non-standard or hard-to-source component, we can work from:
- Original equipment drawings or specs
- A worn or damaged part supplied as a sample
- Site measurements taken from the existing machine
We work with operators across food production, agriculture, chemical processing, and industrial manufacturing — anywhere ribbon blending or similar mixing equipment is in use.
