Machinery & Equipment Co. offers used rotary kilns designed for continuous high-temperature processing of bulk solids in applications such as calcining, drying, roasting, and thermal treatment. Rotary kilns operate by slowly rotating a refractory-lined drum to ensure uniform heat transfer and consistent material processing, making them ideal for handling minerals, chemicals, aggregates, and specialty materials. Common configurations include direct-fired and indirect-fired systems, with options for gas, oil, or alternative fuel burners, as well as integrated feeders, discharge systems, and pollution control equipment. Equipment from recognized manufacturers such as Metso, FLSmidth, Allis-Chalmers, KVS, Polysius, and ThyssenKrupp is often available. Machinery & Equipment Co. can help match the right used rotary kiln based on diameter, length, throughput, temperature requirements, and material characteristics, including access to incoming and off-market equipment.
