fail to regulate pressure of cyclone feed may result to the proble in recovery, so what are these impact for too high or too low pressure?

If the pressure is increased, more fine particles are reported in the overflow (K80 is finer). If the pressure is increased drastically, the hydrocyclone capacity is affected, and more coarse particles can be reported in the overflow. There are some limits to get a finer overflow.

The opposite occurs when the pressure is reduced. For that reason is important to evaluate the optimum operating conditions for a specific process plant.

Basically a higher cyclone feed pressure would mean two things:

Higher wear on the cyclone components.

It will influence the D50 cutpoint of the cyclone to move to being finer and thus more product reporting to the spigot. In extreme cases if excessive material reports to the spigot and overload it it may cause the spigot(apex) to choke and "rope".

Some literature suggests a change in the cyclone efficiency.


Extremely and very low pressure may cause the cyclone inner vortex to collapse and the cyclone to operate erractically or in extreme cases become a T-piece.

I hope this helps.
