WSHT Spiral Classifier (FG/FC Série)

WSHT Spiral Classifier (FG/FC Series)

Capacity: 10-11625 t/d | Precision Engineered for Mining & Mineral Processing

Aperçu des Produits

The WSHT FG/FC Series Spiral Classifier is a mechanical wet classification machine designed for closed-circuit grinding operations and material washing in mineral processing plants. Using the principle of differential settling in an inclined trough with rotating spiral rakes, it provides efficient size classification, desliming, and dewatering of mineral slurries. The spiral classifier is a traditional but highly reliable alternative to hydrocyclones, particularly suitable for coarse classification and applications requiring gentle handling of materials.

Key Features & Benefits

• Reliable Classification
  Proven classification mechanism with adjustable weir height and spiral speed for cut-size control.
• Low Operating Cost
  Simple mechanical design with low power consumption and minimal wear parts replacement.
• Gentle Material Handling
  Low-turbulence classification environment minimizes degradation of soft or friable minerals.
• Dewatering Capability
  Spiral rakes elevate and dewater coarse sand product, producing a low-moisture discharge.
• Single or Twin Spiral
  Available in single (FG/FC) and twin (2FC) spiral configurations for higher capacity requirements.

Technical Specifications

Working Principle

The spiral classifier operates in an inclined trough where feed slurry is introduced at the mid-point. Heavier and coarser particles settle to the bottom and are conveyed upward along the trough incline by the rotating spiral rakes, emerging as dewatered sand product at the top. Finer and lighter particles remain suspended in the overflowing slurry and discharge over the weir at the lower end as overflow (fines product). The separation cut size is controlled by adjusting weir height, spiral speed, and trough inclination angle.

Applications

• Closed-Circuit Grinding
  Classification in gold, copper, and iron ore ball mill circuits for particle size control.
• Mineral Washing
  Washing and desliming of run-of-mine ores, particularly for alluvial gold and beach sand deposits.
• Sand Dewatering
  Dewatering of fine sand products in aggregate washing and construction material processing.
• Oxide Ore Processing
  Classification of weathered and oxidized ores where gentle handling prevents over-grinding.
