Hydrocyclone Selection Criteria and Core Consideration Factors
The selection of hydrocyclones requires a assessment of process requirements, material characteristics, and equipment performance to achieve efficient classification, reduce costs, and adapt to production scenarios. The following explanation is presented from four dimensions: core, key performance indicators, equipment structure characteristics, and application scenario adaptability.

I. Core Process Parameters and Material Characteristics
1. Basic Material Properties
Particle size density: The particle size distribution and density difference in the slurry directly affect the classification effect. For example, high-density coarse particles require greater centrifugal force for separation and to match a large diameter cyclone or high wear-resistant lining.
Concentration and viscosity: High-concentration slurry can easily lead to blockages, requiring a large port design (such as the XCII type involute feed); high-viscosity materials need to optimize the cone angle and overflow pipe size to reduce resistance.
2. Capacity and Classification Requirements
Processing capacity (Q): Determine the cyclone size based on the slurry volume per unit time (m³/h). For large processing (such as medium and large mines), it is recommended to use the XCII type, which can replace the spiral classifier to improve efficiency.
Classification particle size (): The maximum particle size of the overflow (mm) determines the diameter of the cyclone (D). For example, for the separation of fine particles (d<.074mm), it is better to choose the XCIV type, and for coarse particle classification, the XCI type can be selected.
Underflow and indicators: It is necessary to clarify the overflow solids content (such as 1-3%), underflow concentration (such as 50%), and cycle load requirements. example, the XCIII type maintains a constant underflow concentration through a siphon device.
II. Equipment Performance and Structure Design
1. Classification Efficiency and Structure OptimizationFeeding method: Involute feed (XCII type) reduces turbulent flow and improves classification efficiency by 10-15%; three-dimensional spiral feed (X type) eliminates interference near the overflow pipe and is suitable for high-precision classification.
Adjustable structure: The XCIV type's contracted cylinder can precisely adjust the discharge nozzle resistance, and the XCIII type's fish tail device controls the underflow concentration through siphoning, adapting to operational fluctuations.
2. Abr Resistance and Service Life
Lining material: High wear-resistant rubber lining (such as Xinhai Mining Equipment products) extends the service life 3-5 times longer traditional metal and reduces maintenance costs by 40%.
Installation method: Vertical installation is suitable for scenarios with large feed fluctuations, but the sand discharge nozzle out quickly; inclined installation is suitable for constant underflow requirements, with less wear but weaker adaptability to high concentrations.
III. Application Scenarios and Matching Models

2. Other Industrial Scenarios
Flue gas desulfurization: Thepsum hydrocyclone needs to control the overflow solids content at 1-3% (returned to the absorption tower), and 50% of the underflow the dewatering machine; the limestone hydrocyclone controls the slurry concentration at 20-30%, enhancing the reactivity.
Grinding closed-loop: It needs to match the ball mill processing capacity. For example, when the feed fluctuation of the autogenous mill is large, it is necessary to choose a hydrocyclone that can adapt to the variable cycle load.

4. Selection Steps and Precautions
Define basic parameters: Determine the diameter of the cyclone (D) based on the processing capacity (Q) the classification particle size (d), referring to the "D-Q-d" relationship table (e.g., a 500mm diameter cyclone corresponds a processing capacity of 50-80m³/h).
Validate structural compatibility: Check whether the feed mode and adjustable components (such as the sand discharge no and overflow pipe) meet the process fluctuation requirements, for example, high-viscosity materials require a large cone angle design.
Assess long-term costs: Give priority to-wear-resistant materials (such as rubber lining) and easy-to-maintain structures (such as modular design) to reduce annual replacement costs.
Based on the above, it is possible to achieve an accurate match between the hydrocyclone and production needs.
