Parnaby Cyclones delivers High-Performance C&D Washing Solution for Neal Soil Suppliers Ltd, Cardiff 

Parnaby Cyclones has successfully designed and delivered a high-capacity construction and demolition (C&D) washing solution for Neal Soil Suppliers Ltd at their Rumney project site in Cardiff, South Wales. 

The installation features a 170–200 tonnes per hour (TPH) C&D wash barrel plant, engineered to process mixed C&D materials with a maximum feed size of <100mm. The project highlights Parnaby Cyclones’ ability to deliver advanced processing solutions within tight timeframes and with minimal consultation time. 

Following initial discussions and a site visit to one of Parnaby’s high-capacity barrel washing plants operating on a run-of-mine coal project in Merthyr Tydfil, Dauson Environmental Group placed the order in Q3 2022. The new plant was commissioned in August 2023, demonstrating a swift progression from order to operation. 

Parnaby Cyclones collaborated closely with a partner equipment provider to complete the full installation, including mechanical and electrical works. From the outset of commissioning, the wash barrel line consistently achieved its design throughput, producing visibly clean, high-quality materials free from organic contamination. 

At the heart of the system is the Parnaby 8/36 wash barrel, which processes and separates inert materials into three primary fractions: >60mm, <60mm x 4mm, and <4mm fines. The <60mm coarse fraction is further treated in an existing twin-shaft coarse material washer to ensure effective removal of clay contamination, maximising product quality. 

The resulting product range includes: 

- <2mm sand 

- <4mm sand 

- 4mm x 10mm pea gravel 

- 10mm x 20mm gravel 

- 20mm x 40mm gravel 

- >40mm x 60mm washed aggregates 

Final grading is achieved using Neal Soil Suppliers’ existing sand cyclones and screening plant, fully integrating the new system with their established processing infrastructure. 

 The impact of the new installation has been immediate and significant. Neal Soil Suppliers reported excellent product cleanliness and confirmed that the plant is exceeding its original throughput design targets. 

Commenting on the installation, Liam Neal noted an additional operational benefit: 

“The improved cleanliness of both aggregates and sand from the Parnaby barrel wash has enabled higher throughput across our existing log washer and sand cyclone circuits.” 

This project not only demonstrates the performance and reliability of Parnaby Cyclones’ wash barrel technology but also highlights its ability to enhance downstream processing efficiency. 

Parnaby Cyclones would like to thank Neal Soil Suppliers Ltd for their confidence and collaboration on this successful project.
