Grundy & Co Excavations runs a mixed fleet of excavators from 20 to 35 tonnes operating weight, wheeled loaders, bulldozers and tippers. Recycling plant includes three Powerscreen flat-bed dry screeners, with a static trommel and crushing plant completing the eclectic mix. The company specialises in bulk earthmoving, screening, crushing and recycling from their Widnes headquarters, supplying a range of recycled aggregates to building and civil engineering contractors throughout North West England. Over the past ten years, Grundy & Co has always sourced its screening plant from Blue Machinery in Warrington and continues this synergistic business partnership with their new Warrior 1400.
Grundy's Sean Parry says "We're reclaiming upwards of 70% of saleable material from the Liverpool contract, only sending clay and some subsoil to landfill. Our new Warrior 1400 has a three-way split, producing -20mm for filler material, 20-50mm sold on as 6F2 and the 50mm+ going on for crushing to specified size". Due to the old foundations being excavated at Duke Street, a certain amount of tramp metal is being encountered - predominantly rebar - which separates with the oversize, the Warrior 1400 being equipped a finger screen top deck.
The Powerscreen Warrior 1400 is an ideal screening plant for recycling applications - especially when screening and separating comingled C&D waste and oversize materials such as large boulders or tree stumps. The Warrior has a highly aggressive screenbox with hydraulically adjustable screen angles. The bottom deck features a speedharp, or self-cleaning ball deck system, and bottom screens can be easily accessed for changing and maintenance.
The large hopper - with Hardox steel sides and an hydraulically folding rear door to accommodate direct feed from a crusher working in tandem - has a generous capacity and the variable speed incline feeder belt is equipped with impact bars, discharging onto the screenbox from above in order to eliminate bridging.
All the stockpiling conveyors are oversize, hydraulically folding and angle adjustable. The mid-size material falls directly on to the mid-product conveyor, which also features a special "slide-up" system that allows easy access to the bottom deck meshes for cleaning, overhaul or replacement. An overband magnet for extracting metals during screening is an optional extra.
