Why Choose An ABS Spiral Concentrator for Fine Mineral Separation?

The spiral concentrator has long been a reliable tool in gravity separation, and with the introduction of ABS polymer material, its performance and durability have reached a new level. The ABS Spiral Concentrator is widely applied in separating fine particles of iron, tin, tungsten, coal, chrome ores, and more. Below, we highlight its working principle, advantages, and application scenarios.

1.Structure & Material

The concentrator is made from ABS polymer (Acrylonitrile-Butadiene-Styrene copolymer), offering lightweight construction, excellent wear resistance, and strong corrosion resistance. It is ideal for wet, corrosive slurry environments. Each unit is typically designed with 3–5 spiral turns stacked vertically, requiring no power drive — operating purely by gravity.

2. Working Principle

Ore slurry is fed from the top and flows downward along the spiral channel. Through the combined forces of gravity, centrifugal force, friction, and water flow, mineral particles separate by density:

• Heavy minerals settle along the inner edge, where gravity dominates.

• Light minerals move outward with the water flow.

Separation efficiency can be adjusted by controlling feed density, spiral slope, and wash water volume.

3. Core Advantages

• Precision Separation: Tailored designs based on mineral density and size ensure high recovery.

• Durability: Engineered from ABS, polyurethane, and PC alloys, the lifespan reaches 5–7 years, outperforming fiberglass or metal spirals.

• Fine Particle Processing: Effectively separates particles from 0.03–1 mm, handling ultra-fine material better than shaking tables.

• High Recovery & Energy Saving: Operates solely by gravity, reducing energy costs while boosting recovery rates.

• Lightweight & Modular: Easy to install, low maintenance, and efficient for container loading — up to 50 sets per 40-ft HQ container (2.5× fiberglass capacity).

4. Application Scenarios

The ABS Spiral Concentrator is suitable for a wide range of minerals:

• Ferrous: Hematite, ilmenite.

• Non-ferrous: Cassiterite, wolframite, coltan, chrome ore, gold.

• Non-metallic: Quartz sand, feldspar impurity removal.

It is commonly applied in roughing or scavenging stages, as well as in beach sand and tailings reprocessing.

5. Model Selection & Installation

Spiral diameters typically range from Φ600–Φ1200 mm, with capacity between 1–5 t/h, depending on mineral characteristics. For best results, spirals must be installed vertically and level, with multiple units arranged in modular parallel layouts.
