Test work on a dry jig installed at a Balmoral site, covering coal sized below 50 mm and duff below 12 mm, for producers considering waterless beneficiation.
What this report foundA 30 tonne per hour pilot Allair dry jig upgraded run of mine coal to thermal coal specification, but could not effectively beneficiate finer duff.
