The spiral classifier is widely used to pregrading and inspection grading in closed circuits when used in the production flow of metal processing. According to the difference in sedimentation rate of mineral particles and mud, the particle sizes of ores with 1.5mm-0.03mm are classified. Classification equipment---the spiral of overflow end is completely immersed below liquid level.
