Slurry Density Meter successful at South32 Australia

Posted on Tuesday, 14 December 2021 at 02:56

At South32, Cannington – Paste Plant, the Slurry Density Meter (SDM) is now used for almost five years. South32 wants to know how much slurry is going to the storage tank, and measure and control the density for improving and optimizing this stage of the process. 

Kevin Pery, South32, said:

“We installed the density meter in a very
abrasive slurry stream as a trial and it has
performed very reliably for us for four
years. We are using it in an application where
it really picks up the difference between water
and a slurry with 60% solids, and it shows
good accuracy. We are interested in trialling
elsewhere in the plant as potential
replacements of nucleonic density meters to
see if we can remove the risks.”

SDM at South 32 (after four years of operation)

After four years of using the Slurry Density Meter in a very abrasive slurry stream, it is operating well and the sensor is still in a good condition. Due to a small interference of scaling, South32 thought that the sensor had to be replaced. However, it was not needed because the sensor surface was cleaned with a sandpaper, which helped the SDM operate well again.

The staff at South32 experienced several advantages of using the SDM. They did not have to register a nucleonic device to do the same duty and it is a simple and costeffective solution.

• No special licenses
• Good accuracy
• No radiation
• No end-of-life disposal costs
• No sampling
• Real-time and reliable measurements
• No restricted area
