Vincent Dempsey Plant Hire Installs Dernaseer Washing Plant

One of Ireland’s leading plant hire companies Vincent Dempsey Plant Hire, based in Redcross, County Wicklow has recently installed a new Dernaseer sand and gravel washing system at their new sand pit.

The late Vincent Dempsey set the plant hire business up in 1986 to provide machinery to the expanding number of contractors in the local construction industry and the business is now run by his son Kevin who continues to provide plant for muck shifting, quarrying, rock breaking, demolition, wind farms and coastal erosion throughout Ireland. Kevin has now expanded into providing quality washed sand and gravel to ready mix and concrete manufacturers in the Wicklow/Kildare region.

The Dernaseer washing plant features a 30-tonne variable speed belt feed hopper which feeds the two-deck heavy duty scalping screen which rejects the oversize material that is stockpiled for crushing later. The 0-28mm material is conveyed to the 20’ x 6’ (6m x 1.8m) inclined washing screen. The sand is separated to produce two sands which are fed to two DSP Compact Sand Plants which produce a concrete and a building sand. The DSP utilises Linatex slurry pumps as well as Linatex rubber-lined hydroclones and Linatex rubber-lined underflow box and modular polyurethane screen media. The sand products are stockpiled with 18m long powered radial conveyors to maximise stockpiling capacity and reduce material handling. The washed gravels are stockpiled with 15m long conveyors.

Also, with an eye on environmental sustainability and water conservation Dempsey’s have installed a Dernaseer water recycling system as part of their plant. The water treatment plant separates the suspended solids from the hydrocyclone overflow. The settled sludge is pumped to a storage lagoon while the clean overflow water is pumped back to the washing plant. This system recovers up to 90% of water used in the washing process.
