WSHT Spiral Chute Concentrator (5LL Series)

WSHT Spiral Chute Concentrator (5LL Series)

Capacity: 0.15-10 TPH | Precision Engineered for Mining & Mineral Processing

Product Overview

The WSHT 5LL Series Spiral Chute Concentrator is a energy-efficient gravity separation device that uses centrifugal force in a helical flow pattern to separate minerals by density. With no moving parts and low water requirements, the spiral chute provides continuous, maintenance-free operation for processing fine heavy mineral sands and slurries. It is widely deployed in gold, iron ore, chromite, rutile, zircon, and monazite processing plants worldwide.

Key Features & Benefits

• No Moving Parts
  Simple, robust design with no mechanical drive components ensures minimal maintenance requirements.
• Low Energy Consumption
  Zero power consumption for separation — only requires a slurry pump for feed delivery.
• High Fine Recovery
  Excellent recovery of fine heavy minerals in the 10-200 micron size range.
• Multiple Split Points
  Adjustable concentrate cutters along the spiral trough allow production of multiple product grades.
• Compact Design
  High throughput per unit floor area with multiple spiral starts in a single column (2, 3, or 4 starts).

Technical Specifications

Working Principle

The spiral chute operates on the combined principles of centrifugal force, gravitational force, and differential settling velocity. Feed slurry enters at the top of the spiral and flows downward in a helical path along the trough. As the slurry flows, centrifugal force pushes heavy mineral particles to the inner edge of the trough while lighter gangue particles move to the outer edge. Cutters positioned at multiple points along the spiral collect heavy mineral concentrate from the inner zone, while middlings and tailings are collected from intermediate and outer zones respectively.

Applications

• Gold Recovery
  Concentration of fine gold from alluvial deposits, mill tailings, and gravity circuit feed.
• Iron Ore
  Upgrading of specularite, hematite, and magnetite ores by removing silica and alumina gangue.
• Chromite & Manganese
  Concentration of chromite sand and manganese ore from beach sand and hard rock deposits.
• Heavy Mineral Sands
  Processing of zircon, rutile, ilmenite, monazite, and garnet from beach placer deposits.
