Terex Aggresand 165 wash plant installed at Capo Quarry to produce aggregates and concrete sand
BREEDON Aggregates have installed a Terex Aggresand 165 wash plant to produce a range of aggregates and concrete sand at their multi-disciplined Capo Quarry, near Edzell, Scotland.
Supplied and installed by authorized distributors Blue Machinery Scotland, the new plant is a fully modular system capable of processing in excess of 200 tonnes/h of sand and gravel feed material.
Quarried material is fed into the plant’s 9 cubic metre feed hopper, which features a remote-control tipping grid, before being fed on to an inclined conveyor which delivers it to the first processing stage of the Terex Aggresand 165, a 4.8m x 1.5m triple-deck rinsing screen.
Equipped with individually controlled spray bars on each deck, the two-bearing screen is fitted with polyurethane modular screen media on all three decks to wash and separate the material, producing three sizes of clean, high-quality aggregates: 100–24mm, 24–12mm and 12–6mm.
The remaining –6mm material is pumped to a cyclone system which retains all material above 75 microns and produces two grades of sand. Any residual material moves on to a settlement lagoon, with the resulting clean water recirculated back into the system.
Breedon say the new Aggresand 165 wash plant is fulfilling a need for increased volumes of sand at Capo Quarry following the company’s recent success in winning concrete sand supplies to the AWPR contract in the region.
Commenting on the best features of the Aggresand 165, Breedon production manager Bob Hare said: ‘We are very pleased with the large tonnage produced by this versatile wash plant and the modular nature of the Aggresand is a real benefit, giving us the capability of relocating the plant throughout our various sites to accommodate the production demands of current contracts. Another excellent feature is the accessibility to all parts of the plant, meaning that maintenance is straightforward.’
