It is a commonly used concentration and classification device in mineral processing plants, employed for treating various mineral processing products and tailings. The proper selection of equipment is a fundamental guarantee for a processing plant to achieve ideal production standards. The main criteria for selecting hydrocyclones are the slurry handling capacity and the size grading required. When choosing equipment, processing plants must do so in accordance with their actual requirements. When the volume of material to be classified is large and the classification granularity is small, a group of hydrocyclones composed of small hydrocyclones can be used. When selecting hydrocyclones for a processing plant, the first step is to determine the grading particle size based on the mineral processing experiments conducted during the initial design phase of the plant; thereafter, the diameter D of the hydrocyclones is initially determined with reference to mineral processing manuals, using this grading particle size as a guide. The structural parameters of the hydrocyclone, such as the diameter of the overflow pipe d_overflow, the diameter of the sedimentation port d_sediment, the feed port diameter d_feed, the height of the cylinder H, the insertion depth of the overflow pipe h, and the cone angle α, are determined using diameters and the following empirical formulas: d_overflow = (0.2～0.4)D; d_sediment = (0.2～0.7)d_overflow; d_feed = (0.4～1.0)d_overflow; H = (0.7～1.6)D; h = (0.5～0.8)H; α = 10°～45° (higher values for processing coarse particles, lower values for fine particles)
