Successfully processing material at Roan Edge for 10 years.

A significant milestone has been achieved by DUO Processing with ten years of successful contract crushing, screening and washing at Roan Edge Quarry…

The 42-hectare site at Roan Edge has 14 million tonnes of reserves of gritstone. Known as siliceous sandstone this material has a high polished stone value of 60, making it useful for roadstone and other highly desirable materials for the UK’s roads infrastructure and other industries for years to come.

Operating under a crushing, dry screening and washing contract DUO Processing have provided a comprehensive unit cost processing facility which was tailored from the outset to suit the customer’s needs.

Terex® Aggresand 206 Modular Wash Plant:
Featuring a range of state-of-the-art machinery the washing process at Roan Edge is centred around the ‘world beating’ Terex® Aggresand 206 Modular Wash Plant which combines aggregate washing and screening with sand processing on a modular chassis.

In its readily portable format, the Terex® Aggresand 206 Modular Wash Plant is particularly suitable for green-field applications, contractor use and temporary planning permission sites. However, operators more used to static installations will still appreciate the small footprint and minimal site preparations required. In all cases installation time is significantly less than conventional builds thanks to the high level of factory pre-fitting and connections.

At the Roan Edge operation blasted gritstone is loaded by a 50 tonne excavator into several Powerscreen® crushing and screening plants to make a -14mm material. This material is then moved into a dedicated stockpile area where it is fed into the Terex® Aggresand 206 Modular Wash Plant to make clean saleable 14mm, 10mm, 6mm aggregates and a washed sand.

A totally managed contract:
DUO Processing have run, controlled and managed the Roan Edge operation successfully for over 10 years with a team of highly skilled plant supervisors and industry professionals. Supervisors on site monitor the wash plant, water treatment plant and supervise the crushing operations. Plant operators operate the plant machinery across the whole site. Making it run efficiently and to its maximum capacity.

Martin McWilliams – MD of DUO Operations, commented, “This site is producing over 1200 tonnes per day, five and a half days a week and is typical of our “Two Working as One” ethos, we believe that teamwork with the customer, is vital in ensuring that needs are met. We will always, where possible, do what is required to adapt to meet changes in a processing situation. It’s been a total success, ten years of minimising the input to maximise the output.”

A fleet of world class machines:
To achieve this milestone a team of Powerscreen® jaw and cone crushers and screeners has provided a constant 1200 tonnes of crushed output daily.

This has been supported by a range of Doosan equipment, including loading shovels, excavators and ADT’s.

Completing the process, aggregate washing has been delivered by the innovative Terex® Aggresand 206 Modular Wash Plant alongside a thickener tank and filter plant press.

Health & Safety:
Health and Safety is paramount for any DUO Processing managed sites. With our in-house H&S division, STAR; the site is managed stringently, with all procedures adhered to, making Roan Edge a safe working environment for all operatives and visitors.
