Roller Hearth Furnace

 

The roller hearth furnace is a continuous or batch furnace concept that allows processing of small product in trays and baskets or larger product directly on the furnace hearth. The hearth consists of a series of steel, alloy or ceramic rolls which are supported and driven external to the furnace chamber. Furnaces can be provided in electric, direct fired and indirect gas fired configurations to meet specific processing requirements.
