 Washing Feature Story
PowerX Equipment design and
install a sixth Wash Plant for NRS
PowerX Equipment have recently delivered a Wash Plant, Water Treatment Plant and a Filter Press to NRS Waste Care at their new Meriden Park operation near Coventry, to process C&D materials.
This is the sixth plant for NRS that PowerX Equipment has supplied; designed, built and commissioned the plant has an operating criteria to operate up to 150tph and produce sharp, soft and, ultra-fine sand, along with 3 aggregates - 10mm, 20mm and +20mm.
The plant has also been configured that when processing sand and gravel the wastewater and silt will bypass the press and go straight to the lagoon system, utilising the sludge tank feed pump.
The primary recycling waste screen:
The plant is unique in that it features a primary 4.9m x 1.55m, 2-deck screen [bottom flip-flow] which provides the facility to remove the -10mm out before the wash plant.
To achieve this the primary screen has been modified so that both the side conveyors are on the same side, enabling the fines to be fed onto an adjacent reversible horizontal conveyor
[CV1] allowing the material to go forward to the wash plant or by reversing the conveyor to stockpile the -10mm into a bay. The second side conveyor goes directly onto the wash plant feed. The +20mm can also be sized by the screen modules on the screen if required. The oversize material is stocked in a bay for later crushing where sub-base materials are made.
