The spiral classifier cleans and separates the mineral mixture based on the working principle of different particle weights leading to different sediment speeds When the materials pass the magnetic separator they are separated from the mixtures according to their various magnetic susceptibiliti Then the separated minerals are conveyed Apr 28 32 The cooled slurry from the cooling drum 154 FIG 1 is conveyed by gravity flow through lines 240 and 242 to the feedhopper 172 of the spiral classifier 166 The cooled slurry is spirally conveyed from the feedhopper with the rotating screw conveyor blades 178 of the spiral classifier at an upward angle of inclination ranging from 15 176 to 60 176
