Dewatering the -C5 fraction from a cyclosizer (5 replies)

Hi,

I am looking for a centrifuge to dewater the -C5 fraction from a cyclosizer.  Do you know of where I could get one? Do you have an alternative to?

Tried a centrifuge before but it was never successful. Losses were too high. Ended settling in buckets, waiting and decanting.

We routinely used a centrifuge to collect a "CS6" fraction and then gravity settled the "CS7".  Centrifuge had a 3 L bowl and operated at 3000 rpm.

Collection of the finest material is not the only problem.  The large volume of water used by a Cyclosizer can leach the finest fraction because of its high area to mass ratio.  All of this was solved over 40 years ago.  The finest material is separated first by controlled decantation, then the remainder is Cyclosized and, if the procedures have been done appropriately the material leaving the Cyclosizer can be collected very efficiently by any decent bowl centrifuge.  This results in 2 additional valid subsieve fractions - providing more useful data.  

For the full procedure refer to the paper by Stewart and Restarick – Improved Cyclosizing Technique, Proc AusIMM, No.251, September, 1974, pp 9-10.

Hi Marshal, it is worth you sending the required dewatering duty to me, we make both solid bowl and decanting centrifuges. regards mike
