D. P. Williams (Holdings) Limited is a family business and one of the few remaining independent quarrying and merchanting companies in the UK. Extracting and processing limestone from their Aberdo quarry in north Wales, the company has a catchment area of around 60 miles radius from Aberdo, providing a broad range of aggregates, building and dressed stone to the general construction, civil engineering and building industry and builders merchants. Stone is extracted as normal, using drilling and blasting, with the blasted material being crushed and screened with mobile equipment. The deposit contains some lesser quality material, which has previously been thrown away to maintain the quality. After extensive trials of various makes, the company has recently taken delivery of their very first Powerscreen machine - a Warrior 1800 Apron Feeder mobile screening plant from distributor Blue Machinery PLC.

D. P. Williams' new Warrior 1800 Apron Feeder is hard at work in a rather unusual application, pre-screening top bed material from the comparatively young limestone deposits prior to crushing, which would normally be rejected as being relatively  "dirty". The company reports that this innovative reclamation approach is not only increasing the amount of quality clean limestone product available for crushing but is also significantly reducing the volume of material that would normally be wasted and simply tipped and spread as backfill. This reduction in wasted "dirty" material is also likely to extend the working life of the quarry and the company reports that materials-to-waste savings are already in excess of 50%.

The Warrior 1800 is built for tough, high capacity tasks and is equally at home  processing crushed stone, sand, gravel, topsoil, coal or C & D waste. Highly mobile with low ground pressure crawler tracks and aggressive in operation, the machine is capable of screening, three-way splitting and stockpiling and, typically, can be set up ready for operation within 15-20 minutes of arrival on site. Output can be up to 600 tonnes per hour, depending on materials being processed. The Warrior 1800 has compact transport dimensions and its power from a CAT engine and hydraulics are in proportion to the unit’s high performance. One of the most flexible screening machines on the market today, the Warrior 1800 has a highly aggressive screenbox which is able to operate with finger screens, woven mesh or punch plate on both top and bottom decks - the top deck can also operate with Bofor bar. Screen angle is hydraulically adjustable and the bottom deck options include a self-cleaning ball deck system with bottom screens easily accessible for changing or maintenance.

The large hopper - with hydraulic folding Hardox steel sides and folding rear door to accommodate direct feed from a crusher - has a generous capacity and a heavy-duty Hardox lined apron feeder.

All the stockpiling conveyors have a high capacity and are hydraulically folding and angle adjustable. The mid-size material falls directly on to the mid-product conveyor, and an oversize conveyor features a special adjustable system that allows easy access to the bottom deck meshes for cleaning, overhaul or replacement.
