Series F700

Water enters the hydrocyclone via the tangential inlet which creates a spiral flow along the walls of the filter. The centrifugal force separates the waste and sand particles and pushes them towards the walls of the sand separator. Those particles gravitate downwards and into the sedimentation tank, while clean

An insider's look at Multotec's hydrocyclones

The principle behind a hydrocyclone is that the suspension enters the cyclone at a tangent and at high velocity, creating a spinning motion. Consequently, particles that have a larger diameter (or mass) move towards the outer wall, while those with smaller diameter (or mass) move towards the centre of the cyclone.

Hydrocyclone

A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.

Busting Hydrocyclone Myths

The hydrocyclone, in some applications, can replace thickeners but only in situations where the material is extremely coarse and the thickener poorly operated. With very fine material, a hydrocyclone's limitation is that it is impossible to give a highly dense underflow as there is no mechanical means of removing or compressing out the water. 4.
