Inter stage screening (2 replies and 3 comments)

Hello, apart from arranging regular screen maintenance, how can I check for interstage screen leakage manually during the shift?

I am assuming the intertank screens are of the rotating basket type (swept in tank rotating screens).  Sample the discharge on a shift basis and manually screen at say 0.5mm.  If you observe carbon on the screen then you have a leak.

Thanks so you mean the oversize or undersize?

no carbon is suppose to be visible when you do the check on the discharge sample, if any carbon is visible it will mean : 1. if its finer than the screen appeture it will mean you are creating fines in your system,2.if its coarser than the screen appeture then it will mean you have leaks.

A quick check can be carried up by placing something as simple as a kitchen type wire sieve fixed to a pole into the discharge stream to see if carbon granules are escaping. Construction of similar implements with a proper screen mesh can usually be quickly made on a mine site to do the same job.

Thanks for the good idea
