Rotary kiln (Rotating retort furnace)
aboutWhat is a rotary kiln?
Rotary kiln, also known as a rotating retort furnace, is a heat treatment equipment mainly used for powder materials. The furnace operates by stirring the powder material inside its rotating muffle, ensuring uniform drying and heat treatment. Sun Furnace Co. Ltd is a leading supplier of rotary kilns and provides services from design to installation and maintenance.
The company can offer batch type furnaces that can change atmospheric gas during heat treatment and supply muffles with excellent corrosion and heat resistance.
Sun Furnace Co. Ltd also offers the most suitable product feeding system based on the viscosity of the products to be treated, such as screw type or vibration table type.
featureFeatures
Batch type furnace can change atmospheric gas during heat treatment.
Atmospheric gas can be changed at the target temperature during heat treatment based on the characteristics of the products. This changing of atmospheric gas is especially effective when using expensive atmosphere gas during the start of heating.
Sun Furnace Co., Ltd can supply muffles with excellent corrosion and heat resistance.
Depending on the material being processed, corrosive gas may be produced during the heating process due to chemical reactions. Sun Furnace Co., Ltd will select appropriate materials for the muffle and manufacture a muffle that meets the characteristics of the product being processed.
