European Giant at Holme Hall

1st April 2004

Holme Hall Quarry, a Tarmac Central operation at Stainton, Nr Maltby in South Yorkshire has recently purchased a Gipocombi RC 170FDR mobile combination crusher and screen.

Supplied by Aggregate, Processing and Recycling of Tamworth this 137 tonne machine is the largest of its kind in Europe. The new Gipo machine will eventually be linked by conveyors to a static secondary and tertiary limestone crushing plant currently still under construction.

This giant of a machine provided to Holme Hall has a high specification; a tracked heavy-duty chassis carries a P170 impact crusher with a variable speed 1.4 dia x 1.7 wide rotor including hydraulic adjustment and hydraulic blockage release system.

Material is fed by hydraulic excavator into the hopper which has a capacity of 12m3. To comply with safety regulations this has an integral hydraulic breaker to free any blockage that may occur in processing material. The feed then passes through a 4.5 x 1.7m two deck pre-screen; finer material is screened onto a reversible side exit belt feeding a radial scalping conveyor to provide a large stockpile.

The middle sized stone can bypass the crusher via the integrated bypass chute; oversize material is then fed into the impactor which then feeds crushed material together with the bypassed material to the 1.7 x 2.5m crusher feeder situated directly beneath. A 1.9m long transfer conveyor then feeds the material to the 7m x 2m two-deck final screen which feeds two stockpile conveyors and the oversize recirculation conveyor; this screen also has a bypass facility allowing all stone to be stockpiled from one conveyor without screening. Additionally, the oversize radial return conveyor provides the option of stockpiling oversize stone, or alternatively, conveying the material back to the crusher in close circuit.

The RC 170FDR is powered by a 1000 HP motor complete with fully hydraulic variable speed drive.

With a weigh-in at approximately 137 tonnes, this is a true European Giant!
