Gravity Spiral Separator Chute

Gravity Spiral Separator chute

1.Product Introduction 

The spiral separator is a core gravity separation device in chromium ore beneficiation lines. It is primarily used to achieve high-efficiency

separation based on the density difference between minerals and gangue. It is particularly suitable for processing fine-grained (0.02–2mm)

chromite placer ores or ground materials. Within a complete production line, the spiral chute often handles roughing, scavenging, and even

cleaning tasks. Its notable advantages include zero power consumption, a simple structure, and high processing capacity.

2.Application

The spiral separator is suitable for separating fine-grained (0.3--0.02 mm) materials, including iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite,

tungsten ore, tin ore, tantalum ore, niobium ore, and other non-ferrous metals, rare metals, and non-metallic minerals with specific gravity differences.

4.Advantages 

• Applicable Particle Size: 0.02–2mm; particularly suited for the separation of fine-grained chromium ore.

• Feeding Concentration: Generally controlled between 20%–30%; concentrations that are too high or too low will negatively impact separation efficiency.

• Processing Capacity: A single unit can process 2–40 tons per hour (t/h), depending on the specific model (e.g., 5LL-1200, BLL-Φ600, etc.).

• Process Configuration: Multiple units are often used in series (multi-stage circuits) to achieve a comprehensive recovery flow of roughing → scavenging → cleaning.

• Eco-friendly & Energy Saving: Features no moving parts and requires no power drive; characterized by low water consumption and minimal operating costs.
