Roping HydroCyclone -Bad Operation

HydroCyclone Roping – Incorrect Cyclone Operation is often caused by too high a volume feeding into the cyclone. If the apex capacity is exceeded a condition known as roping may occur. Normally, the underflow sprays out of the apex. When roping occurs, the air core inside the apex collapses and the spiraling motion is almost lost. The discharge looks like a rope. In extreme cases, roping can ...

Using IIoT to prevent hydrocyclone roping - The Weir Group

Key causes of hydrocyclone roping and how to prevent it . Roping can occur when pressure is increased without achieving the required slurry density, which differs according to the application. For example, hydrocyclones processing low density materials such as tailings slurries are less prone to roping.

With a Hydrocyclone, this is accomplished by adjusting the spigot size. Too small of a spigot will cause roping in the Hydrocyclone and decrease separation efficiency, while too large a spigot will increase the bypass. For these reasons, Hydrocyclones work best when the throughput or tph is consistent.

Hydrocyclone Feed Pump & Pressure PSI vs Operating …

For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation. First the pump pumps all of the slurry out of ...
