The working principle of hydrocyclone - LZZG

The particles reaching the wall are pushed by the liquid above the cyclone and move down the wall. When it reaches the vicinity of the underflow orifice, it condenses into a suspension with a higher degree of viscosity and is discharged from the underflow orifice. The separated liquid rotates downward and continues to move.

Spiral Concentrators — IMSC Group

Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral trough.

Gravity Spiral Concentrator Working Principle

The processes involved in mineral concentration by spirals are similar for all models. As feed containing 25-35% solids by volume is fed into the channel, minerals immediately begin to settle and classify. Particles with the greatest specific gravity rapidly settle to the bottom of the spiral and form a slow-moving fluid film.
