Operating out of the Isle of Axholme, North Lincs Sand & Gravel (NLSG) is a well-established privately owned company that has grown to be one of the region’s largest suppliers of aggregates, plant machinery and contracting services which operate out of their own quarries.
Having operated a silica sand quarry at Blaxton, Finningley, near Doncaster for many years NLSG have recently acquired a greenfield site which is situated almost opposite. This new site contains an estimated reserve of 3.5 million tons of sand and gravel.
To process this material NLSG have invested in two Terex Wash plants; a FM200C Sand Recovery Plant and an Aggresand ™ 165 Modular Wash Plant which have been supplied by UK dealer PowerX Equipment.
Richard Mills – MD of NLSG, took up the story, “We have invested in two plants, one to process the soft sand and a second larger plant which will process the gravel, all of which will be sold to local markets including tile factories, brick block making factories and mortar plants.”
FM200C Sand Recovery Plant:
To process the soft sand PowerX installed and commissioned a Fines Master 200C Sand Classification Plant including pumps, pipework, and electrics in the summer of 2021, which has been designed to process up to 200tph. All as-dug material is delivered to the H12 feed hopper and conveyed by feed conveyor onto a 16 x 5 double-deck rinsing screen with modular support structure. Here the top deck acts as a protection deck removing any oversize rejects with the bottom deck providing the feed to the sand recovery unit.
This low maintenance unit combines a collection tank, centrifugal slurry pumps, twin G4 hydro cyclones and a 4.3 x 1.8m dewatering screen with spray bars mounted on a single chassis which recovers the required one grade of sand maintaining a maximum recovery of saleable material through the removal of silt, slimes, and clays below 75μm (200 mesh). All saleable material is then delivered to a radial sand stockpiling conveyor.
The electric plant has been manufactured with a robust, easy to assemble steel construction, complete with galvanised walkways and handrails throughout to provide easy and safe access. The whole plant footprint sits on a concrete pad including driveway and access to the H12 feed hopper.
Richard, continued, “We have had a long and successful relationship with PowerX Equipment over the years and always found them very professional and very quick to respond. It made perfect sense to continue our relationship and invest in these two new plants. We cannot really fault them; they are always proactive which is perfect as we cannot let customers down!
Aggresand ™ 165 Modular Wash Plant:
This plant is currently being assembled on site and will be commissioned late November and provide NLSG with two grades of sand and a 10mm and 20mm aggregate.
The NLSG Terex® high performance AggreSand 165 modular wash plant combines aggregate washing and screening with sand processing on a modular chassis. It brings together tried and trusted Terex® Washing Systems components in an innovative modular design, setting itself apart from other washing systems in the marketplace. The plant includes an H12 feed hopper which delivers material to a feed conveyor and onto a 3-deck 16 x 5 screen box with modular support structure. This separates the two aggregates and delivers the sand to a Fines Master 200c Sand Classification Unit, with all materials being stockpiled by radial conveyors.
Richard added, “We chose the 165 because it can process a large tonnage which will enable us to keep up with the demand.
“Also, screening is through polyurethane mats which are considerably better and offer less maintenance. Unlike the first plant all the as-dug material in this instance will come off a Powerscreen Warrior 2100 tracked scalper which will feed material direct into the plant hopper.”
This Powerscreen 2100 tracked scalper was originally supplied by PowerX Equipment and includes triple shaft technology which is unique to Powerscreen heavy-duty screens. This triple shaft design ensures that the 16 x 5 screen box is highly efficient while maintaining exceptional throughput productivity.
Luke Talbot – MD of PowerX Equipment, added, “This is our fourth plant installation for NLSG alongside the supply of various mobile crushing and screening machines. We have worked with NLSG for some considerable time and have always ensured that the investment they have made is operating efficiently, processing and providing saleable material.”
