BREEDON Aggregates has taken delivery of a new Terex Aggresand 165 wash plant, which is producing a range of aggregates and concrete sand at their Capo Quarry in Edzell, Angus.
The wash plant was supplied by Blue Machinery Scotland and has been described as a “fully modular system capable of processing in excess of 200 tonnes per hour of quarried sand and gravel feed material”.
Blue said, “The washing process at Breedon’s Capo Quarry sees the quarried aggregates fed into the plant’s 9m³ feed hopper, which features a remote control tipping grid. The material is then fed onto 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 box.
“Equipped with individually controlled spray bars on each deck, the two-bearing screens are fitted with polyurethane modular screen media on all three decks which wash and separate the material, leaving three sizes of high quality aggregates – 100-24mm, 24-12mm and 12-6mm. The remaining 6mm-0 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 lagoon to be filtered, with the resulting clean water recirculated into the system, improving water recycling and reducing waste in the process.”
Breedon’s new wash plant is said to be fulfilling a need for increased volumes of sand following the company’s success in winning concrete sand supplies to the AWPR contract.
Bob Hare, company production manager for Breedon Aggregates, 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. This plant’s excellent performance is proving to be a major contribution to our requirement for increased volumes of high-quality end-products”.
