Metal Turnings Washing Services
William Rowland Makes Significant Investment in Turnings Processing Line
Our new facilities can now provide specialist metal turnings and swarf washing services. We are one of the rare metal companies in the UK providing turnings crushing service (subject to an initial XRF inspection), cleaning and drying process to allow an upgrade to superalloys and compression for improved density through briquetting of washed turnings.
Get in contact today to discuss your needs.
On receipt each batch of turnings will be assigned a unique identification number to ensure lot traceability throughout all of our processes. Each batch of metal Turnings will be crushed separately with thorough clean downs in between batches and/or campaigns to minimise contamination risk.
Turnings are subject to XRF inspection prior and then throughout crushing to give suppliers swift initial feedback. Turnings are then crushed with the use of a ring mill crusher to ensure a uniform size of chip that is free flowing for consistent cleaning.
Each lot of Turnings will be subject to a thorough sampling procedure to determine, major and trace elemental analysis. This is performed in our onsite laboratory for quick turnaround. Where customers require accredited laboratory testing, William Rowland also offer this.
Cleaning and Drying Process
Working with the equipment supplier William Rowland have designed a bespoke Turnings cleaning facility that allows us to upgrade Superalloys to customer specifications to enable recycling of the material back into a vacuum melting application. Each batch of Turnings will be cleaned separately to ensure lot integrity and traceability is maintained. An Aquarius Wash System is used which is better for the environment and enables faster process times, for quicker material turnaround. Fines Separation removes smaller fine material that can inhibit high Oxygen & Nitrogen. In the Dryer, material is dried at temperatures that minimise the pick-up of excess Oxygen & Nitrogen throughout.
Magnetic Alloy Separation and Processing with the use of powerful overband magnets ensures separation and segregation of magnetic material from non- magnetic products. Our process also allows us to reverse the process and remove non-magnetics from magnetic alloys.
In-line process control allows us to monitor product quality throughout our process with the use of Carbon & Sulphur Gas analysers. Flow sampling is then used from start to finish to ensure consistency and each batch is provided with full certificate of analysis.
Improved density through briquetting of washed turnings
For material that is low in density we can compress material into ‘pucks’ of 70-90mm Dia and weighing 1-1.5 kgs, this process improves density and reduces the amount of packaging, which in turn can reduce transport costs. Again, each lot will be processed separately and in entirety to ensure lot traceability throughout.
