FX Series High-Efficiency Hydrocyclone Cluster for Classification & Separation

The FX Series Hydrocyclone Cluster is a modular classification and separation system composed of multiple hydrocyclones arranged in parallel or series configurations. Renowned for its exceptional classification efficiency, compact structure, large processing capacity, and absence of moving parts, the FX Series has become a core piece of equipment in modern mineral processing, coal preparation, aggregate production, environmental protection, and chemical industries.

Based on the principle of centrifugal sedimentation, the hydrocyclone cluster generates a strong rotational flow field inside each cyclone, enabling rapid and efficient separation of particles with different sizes and densities. Compared with traditional mechanical classifiers, hydrocyclones offer faster response, higher separation sharpness, and significantly lower maintenance requirements, making them indispensable in continuous industrial processes.

As a primary classification unit in closed-circuit grinding systems, and a critical component for desliming, thickening, and separation stages, the FX Series Hydrocyclone Cluster plays a decisive role in improving overall process efficiency, product consistency, and operational stability.

The FX Series Hydrocyclone Cluster is engineered as an integrated, rigid assembly that combines multiple functional modules into a single, reliable system.

Hydrocyclone Units (Core Elements)

Each hydrocyclone features a conical-cylindrical structure and is typically manufactured from:

Wear-resistant polyurethane

Ceramic materials

Rubber-lined steel shells

A standard hydrocyclone consists of:

Cylindrical section

Conical section

Feed inlet

Overflow pipe (vortex finder)

Underflow nozzle (apex / spigot)

This optimized geometry ensures stable internal flow patterns and high separation accuracy under varying operating conditions.

Feed Distribution Manifold (Key Component)

The feed distributor ensures that incoming slurry is evenly, steadily, and pressure-balanced to each hydrocyclone. Uniform feed distribution is critical to maintaining consistent classification performance across the entire cluster and preventing efficiency losses caused by unequal loading.

Overflow Collection Launder

All fine particle products discharged from the overflow outlets are collected through a centralized launder system, ensuring smooth downstream transport and preventing turbulence or material buildup.

Underflow Collection Hopper or Trough

Coarse particles discharged from the underflow outlets are collected through a dedicated hopper or launder, allowing easy integration with subsequent grinding, screening, or dewatering equipment.

Rigid Steel Frame

All hydrocyclones, manifolds, and collection systems are mounted on a heavy-duty steel frame, providing:

Structural stability

Accurate alignment

Ease of installation and maintenance

The modular design allows flexible configuration according to capacity and process requirements.

Valves and Instrumentation

To ensure precise control and monitoring:

Observation spigots or pressure indicators can be installed at individual underflow outlets

Pressure gauges and flow meters are commonly installed on the feed pipeline

These instruments enable real-time monitoring of operating conditions and quick troubleshooting.

Mineral Processing Industry

Closed-circuit grinding classification
Used in combination with ball mills to separate qualified fine particles from mill discharge, while returning coarse particles for regrinding—essential for improving grinding efficiency and controlling product fineness.

Desliming
Removes ultra-fine slimes prior to gravity separation or flotation, significantly improving downstream separation performance.

Pre-thickening
Performs initial slurry concentration before thickening or filtration stages.

Dense medium recovery
Widely used for recovering heavy media such as magnetite in dense medium separation circuits.

Coal Preparation Industry

Applied in coal slurry classification, thickening, and clarification processes, contributing to improved water recovery and reduced environmental discharge.

Aggregate and Manufactured Sand Industry

Manufactured sand classification
Controls fineness modulus and separates excess stone powder to meet concrete and mortar specifications.

Fine sand recovery systems
Serves as the core classification unit in integrated fine sand recovery equipment.

Environmental Protection and Chemical Industry

Used in industrial wastewater treatment for solid-liquid separation and classification of particles with different densities and sizes.

Extremely high classification efficiency

Large processing capacity with compact footprint

No moving parts, resulting in low maintenance and high reliability

Flexible modular configuration for various process requirements

Stable operation under high-pressure and high-concentration slurry conditions
