Two 7500 litre JR Boone horizontal large-scale paddle mixers have been installed in FCC Environment’s Knostrop treatment plant in Leeds to treat and stabilise air pollution controlled residue waste from a network of incinerators.
Chosen for their robustness and reliability, the new mixers are now processing 25,000 tonnes per annum, producing a stable material for safe landfill, says JR Boone.
A high percentage of silica sand in the mix makes the process very abrasive, so the mixers are fitted with wear-resistant mixer arms and blades, with the number of moving parts minimised.
Between them, the two machines process 20 tonnes of waste material per hour.
