AKA-SPIN spirals are used to separate materials (60 μm – 2 mm) according to their different densities.

Principle of Operation

The slurry is fed into the spiral from the top and moves down by gravity. A transverse flow is superimposed on the main flow downwards.

This combination results in the separation of the particles contained in suspension, depending on their density. Particles with a lower specific gravity are concentrated in the outer areas of the flow. Particles with a higher specific gravity are directed towards the spiral axis.

Design Features and Client Benefits

• Separation of up to 3 fractions: heavy, middling and light density particles
• Wear resistant polyurethane coating of the spiral body
• Light weight and robust design
• Spirals can be designed to fit into columns and banks
