Rotajet metal turnings & Swarf Recycling
In-house metal washing solutions.
Rotajet specialises in degreasing 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 specialized 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 recycling 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.
Rotajet SIB Wash method
-
Submersion
The swarf is submerged into to a heated bath of environmentally friendly wash chemicals. This stage ensures every internal and external surface of the swarf cut turnings comes into contact with the wash solution and contamination and oils can be targeted, even from fine ridges.
-
Impingement
The overhead spray bars impinges the surface of the swarf causing a mechanical physical action on the turnings surface to degrease and decontaminate. The movement of the screw also causes a mechanical friction action for further impingement.
-
Backflow
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.
Saving water with the Recirculation tank
-
Wash tank
Wash solution is heated and recirculated into the cycle from the wash tank.
-
Pressure filter
The in-line pressure filter is used to filter the wash solution with interchangeable 100, 400 or 600 micron options.
-
Spray bars
The solution is then pumped to the overhead spray bars where it is impinged through the high flow knife jets directly onto the materials surface.
-
Circular sieve
The solution flows down the screw and drains out to the vibro sieve where the liquid if filtered through a 300 micron screen to remove any fines and solid picked up through the swarf. This is fed back into the wash tank.
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
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.
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.
Rotajet are the experts in the design and manufacture of cleaning and degreasing machinery. We’ve worked with some of the worlds biggest brands to create intuitive systems to repurpose, repair and manufacture metal and plastic components.
