Daniel Charles Aggregates invest in a PowerX Recycled Washing Plant & Water Treatment System
Daniel Charles Construction Ltd was established in 2005 as a traditional style construction company with the aim of becoming the clients’ first choice. Since then, the business has gone from strength to strength with Daniel Charles Surveys added in 2007 and the acquisition of Len Kirk Plant Hire in 2021, now known as Daniel Charles Aggregates (DCA).
Operating from their head office at Dunholme, along with Kirks Yard at Whisby Road, Lincoln and Kirks Quarry at Dunston, they have amassed a dedicated and skilled workforce encompassing Plant & Quarry Operatives, Groundworkers, Site Managers, Health and Safety Manager, Contract Managers, Mechanics, Engineers, Surveyors and Head Office staff.
Investment:
Recently DCA have invested in a new Recycled Washing Plant & Water Treatment System which after the usual contract process was awarded to PowerX Equipment. Founded by industry specialists with decades of experience in this market PowerX Equipment are recognised as a market leader and the next generation in aggregate and mineral processing.
This new plant was installed and commissioned in 2023 at Kirks Quarry, Dunston which is situated south-east of Lincoln.
Kirks quarry has extensive reserves of limestone and a few hundred thousand tons of processed C&D waste where the fines have been removed from the product to create a saleable topsoil. [All material is delivered from the companies own C&D sites in the area along with a small waste transfer station in Lincoln].
Prior to the installation of the plant multiple sample analyses were taken of the inert C&D stockpiled waste after it had passed through a Warrior and designated the middle product. The limestone fines coming off the crushing train were also analysed to understand how much of a benefit washing this by-product would have on the process.
Washing Plant
The plant at Kirks Quarry is centred around an all-electric washing plant, integrating heavy attrition with sizing, lightweight contaminants removal and hydro cyclone based fines recovery on a single highly portable chassis.
Primarily designed for the processing of construction and demolition waste but equally suited to virgin material applications. This recycled aggregate processing plant is capable of producing four grades of aggregate and up to two grades of sand at up to 70tph.
Plant process:
After pre-screening on site, material is then delivered by wheel loader into a 7.5m3 double-deck, live head, heavy-duty hopper. Material is then fed up a 16-metre inclined conveyor and under a ferrous metal overband magnet and delivered onto the Washing Plant where the material is rinsed, scrubbed, and sized through a 2.4m x 1.2m single-deck rinser, which features six isolated spray bars.
Jim Clarke – Quarry Manager, commented,
“When we looked at all the plans from the various suppliers, PowerX Equipment were the only one who offered us exactly what we wanted.
“From the start of the project to commissioning it was almost a faultless project. They have since ‘start-up’ being with us to assist which is very reassuring and minimizes downtime. All the production team are very happy with the plant build and the support from their engineers when needed.”
