Aggregate, Processing and Recycling Ltd (APR) - as the UK and Ireland agent for GIPO, has recently supplied a GipoCOMBI RC130FDR mobile crushing and screening plant to Ewenny Quarry in Bridgend, South Wales.
Owned and operated by Lafarge Aggregates, one of the UK's leading aggregate companies, the quarry supplies product to the whole of South Wales.
With the quarries static aggregate crushing plant currently processing single size material the new GipoCOMBI RC130FDR is being utilised as a primary & secondary crusher which operates at 180tph processing "as-blasted" limestone into 0-5 and 5-25mm aggregates.
The GipoCOMBI RC130FDR supplied for the project is a heavy duty, highly efficient machine of compact design which is driven by a Caterpillar C15 engine supplying 430kw in total, allowing 380kw + to be applied to the crusher. Featuring a dual-zone blockage release system, the variable speed P130 impact crusher allows maximum variance on output grading; all gap adjustments are hydraulic and crusher inlet + top apron have hydraulic lift for blockage reduction.
A variable speed feeder supplies the blasted limestone to a 2 deck pre-screen with scalping at 0-40mm and crusher bypass facility. Crusher discharge is catered for with the provision of a tray feeder as standard to absorb impact and protect the conveyor. Final screening of material is performed by a 4.5 x 2 metre - 2 deck screen incorporating a 25mm aperture top deck and a 5mm aperture bottom deck.
To ensure optimum dust suppression the machine is fitted with a system including an on-board stainless steel tank and water pump which supplies spray bars at the crusher inlet / outlet and also to all conveyor heads.
Additional features include aluminium covers on all conveyors, plus walkways and maintenance platforms around all relevant parts of the machine for easy maintenance.
The GipoCOMBI RC130FDR has significant advantages over other machines as it utilises a system of combined crushing and screening in closed circuit, achieving maximum efficiency. With fuel consumption significantly lower in comparison to a separate crusher and screen, the machine also has the advantage of a much quicker set-up and movement times than when aligning two separate units.
Other major advantages include the reduction of loading and stockpile clearing activity. Once material is fed into the GipoCOMBI it is contained within the machine until the process is complete, hence no extra work, or fuel usage on loading shovels handling oversize stone back to the hopper.
Maintenance is well catered for as the machine has only one engine and not two, and features less conveyor belts overall than the combination of a separate crusher and screen, resulting in less risk of downtime and lower service costs.
