Multiple Hearth Furnaces available from M&E are used for continuous thermal processing, calcining, roasting, drying, activation, regeneration, and incineration of a wide variety of bulk materials. These furnaces utilize multiple refractory-lined hearths with rotating rabble arms to move material through successive heating zones, providing efficient heat transfer and precise process control for continuous operation. Multiple hearth furnaces are commonly used in the mining, chemical, environmental, activated carbon, wastewater treatment, metallurgical, and minerals processing industries for applications such as ore roasting, carbon regeneration, sludge incineration, lime processing, and catalyst treatment. Available equipment may include gas-fired and electrically heated systems in a variety of diameters, hearth configurations, and operating temperatures. Our inventory may feature equipment from leading manufacturers such as Nichols, BSP Thermal Systems, Industrial Furnace Company (IFCO), Surface Combustion, Lindberg/MPH, and other recognized thermal processing equipment suppliers. Contact M&E to review current availability or to source a used multiple hearth furnace that meets your material, throughput, and process requirements.
