Unique design

nnnn

It's all by design - Cavex® hydrocyclones feature a unique laminar spiral inlet

nnnn

geometry designed to deliver excellent efficiency and capacity, and longer wear

nnnn

life than conventional involute or tangential fed cyclone designs. Not just a cone

nnnn

modification, Cavex® hydrocyclones utilize an entirely new feed geometry that

nnnn

allows the slurry to follow a natural flow path within the cyclone. This results in

nnnn

a reduction of turbulence which in turn substantially increases hydraulic capacity

nnnn

while minimizing localized wear on the feed chamber and vortex finder. The

nnnn

unique shape of the Cavex® hydrocyclone has no sharp edges and no corners.

nnnn

These design improvements result in lower operating costs and fewer cyclones

nnnn

required for a given duty.

nnnn

Higher separation efficiency

nnnn

When turbulence is reduced, sorting efficiency is enhanced. As shown in the

nnnn

illustration, fewer misplaced fines report to the underflow and less grit reports to

nnnn

the overflow.
