  • 6 Factors Affecting Hydrocyclone Efficiency

    14 05 2020  If particle size of the ore feed is fine and the feed pressure is high the ratio of the feeding port to the diameter of the hydrocyclone is usually maintained at 0.14 to 0.16 In addition the shape of the feed port often rectangular and the feeding method tangent or involute also have some effect on the classification efficiency.
