Rotor with spiral formations on the rotor blades (Figure 1). Two rotors which work in opposite directions are usually used (Video). The shape of the rotor blades enables energy-saving and uniform mixing of aluminumchips. Through the deep penetration of the chips in the melt and the associated rapid melting, the melting power and efficiency of the furnace are increased.
