North Lincs Sand & Gravel increase their processing power with twin PowerX Equipment installations
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 TM 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.
