Rotajet metal Swarf Cleaning
In-house metal washing and dry line
Companies Using Rotajet Swarf Cleaning
Rotajet specialises in machines designed to process high-value metals and super alloys produced during the machining process. Our lines are engineered to wash, decontaminate, and dry swarf, preparing it for vacuum melting.
The Rotajet Advantage:
- Impeccable cleaning: Our specialised SIB method ensures thorough cleaning, even in the most intricate areas of the metal surface.
- Reduced carbon levels: Surface carbon levels are consistently reduced to less than 5%.
- Optimal preparation: Swarf is prepared to the highest standards for vacuum melting.
How do we wash metal turnings?
Oils can be particularly tricky to clean off a surface… Due to the nature of the substance, physical impingement or heat are not always enough to do the job alone. Especially in the case of metal swarf, it is essential that the material is thoroughly clean and free of any oils or contamination, as any leftover residue can cause defects and serious problems in the end product.
Our wash lines use the Rotajet SIB method, to combination of all four washing methods—chemical washing, heated washing, and physical impingement, to ensure the out-feed material is completely oil and residue-free.
The Rotajet Turnings line explained:
The Rotajet metal turning line is comprised of three main sections: wash, rinse, and dry, with an in-feed hopper on the front end and a bagging off station for the out-feed.
Since this line is comprised of modular machines, the layout can be turned and changed to accommodate floor spacing and facility requirements. The machines are also available as individual machines and can be retrofitted into an existing facility or space.
1. Submerge
Metal turnings are immersed in a heated bath of eco-friendly cleaning agents. This process guarantees that every nook and cranny of the swarf is thoroughly cleansed, removing contaminants and oils even from the tiniest ridges.
2. Impingement
Overhead spray bars forcefully spray the swarf, mechanically dislodging grease and contaminants from the surface. The rotating screw creates additional friction, further enhancing the cleaning process.
3. Back-Flow
The liquid from the spray nozzles flows back down the screw forming a constant stream. This delivers a final flush to the swarf to ensure the internal surfaces of the turnings are thoroughly washed.
Installing the machines
Configurations to suit you
Our in-house team can custom design your plant to fit into your factory floor plans to streamline your production and maximise space.
This can be done to fit the plant into tighter areas, aid an existing process or to ensure input collection and the output feed correspond with your work flow.
Worldwide delivery
This line was manufactured, assembled, and tested in Rotajet’s UK facility complete with a Factory Acceptance Test (FAT) to ensure the agreed throughputs and cleaning specifications were achieved.
The machine was then disassembled and shipped to Singapore. Rotajet engineers installed and commissioned the machine, followed by onsite training for the local operators . Thanks to the Rotajet team’s methodical approach, the smooth installation allowed the customer to quickly maximise the machine potential.
From Singapore to Spain, Rotajet deliver and install machines worldwide. We provide on-site engineers with the appropriate training and and will provide on-hand support.
The Rotajet Pre-Washer
Our Rotajet Pre-Washer is ideal for:
- Heavily contaminated turnings:
This machine can be used as an added step to ensure that the turings are thoroughly cleaned. The prewasher not only speeds up the process but also prevents the next stage from becoming contaminated, saving you time and effluent use. - Lightly contaminated turnings:
For turning with little to no contamination and needing a quicker wash to ensure a clean and usable product
Industry Uses of Swarf Degreasing
Advanced Alloys
Rotajet Systems, based in Wakefield, UK, have recently installed a Swarf Degreasing Line at the Advanced Alloys facility in Thailand. The new equipment provides an advanced, energy-efficient solution for cleaning and recycling superalloy turnings to vacuum melt grade standards — helping reduce waste and promote a circular economy in high-value metals.
William Rolands
Rotajet Systems Limited have been adapting in these unprecedented times, however continuing production of our world leading recycling technologies. We are pleased to announce that a RJ-RDW turnings degreasing line has been installed for William Rowland Ltd (WR) .
DMT
Rotajet Systems Limited, a UK based machinery manufacturer, have recently installed a superalloy turning cleaning, degreasing, and drying line to DMT (Donald McCarthy Trading Pte Ltd), Singapore.
