' pagi,

Flotation would seem to be your better method.

Drum separator manufacturers have poor delivery schedules and offer very poor support. Any principal supplier will probably have to refer your enquiry to the Australian office who could not serve the local market properly; with or without the mythical demand surge from China. It isn't rocket science to quantify the equipment if you know the throughput and hydraulic loading. Unfortunately manufacturers' seem to think it is (rocket science); probably because they use words like Nyobium & Zirconium. I always suspected that those expensive elements were the reason for the extraordinary long lead times for the equipment.

Flotation cells will be available sooner; dosing & feed rates can be controlled easier & more accurately by turning a few valves.

If you have to alter drum separators there is only so much you can do with belts and pulleys against a fixed feed rate.

But see what offers come down in the shower. ■

I believe this job would probably be best suited to what we call a DENSITY SEPARATOR.

a company I worked for used to peddle this device and actually in its proper niche market did a wonderful job, basically by gravity separation by difference in specific gravity of different type of intermingled materials.

BASICALLY, SIMPLY .......the principle is a sink float device, vs say a aggregate classification tank.
