By combining the proper submergence of the spiral with one of the tank designs a choice of 63 combinations is possible in Straight, Modified or Full flare tank designs. The proper combination of pool depth, area and spiral construction is important to secure a controlled turbulence in the slurry flow for accurate size separation.

Spiral Classifiers are suitable for:

• Separation of fine particles and liquid from coarse particles
• Separation of light particles from heavy particles
• Separation of the particles into a number of products graded according to size
• Separation of liquid from solid particles

Main benefits of Spiral classifiers:
