Harper International received a contract for a high-volume rotary furnace system from Prayon, a global phosphate producer headquartered in Belgium. The system will be used for drying and calcining of Prayon’s iron phosphate powder, a key component of lithium iron phosphate cathode materials used in rechargeable batteries for electric vehicles. The gas-fired rotary kiln includes advanced tube features to provide enhanced reaction kinetics, gas-tight and dust-tight design, and internal heat recovery within the furnace chamber to improve energy efficiency.
