They provide continuous efficient service desliming ahead of flotation, classifying, degritting
or dewatering, Emanuel said.
The clever bit is inside: a patented gas mixing system on a rotating degritting
7 is to blunge the clay usually at about 15 to 20 percent solids to disperse the bentonite and release the grit sized particles such as quartz, which can then be removed by screening or by a degritting
centrifuge or a hydrocyclone.
Finham currently consists of two separate inlet works, at the Sherbourne and the Sowe, each providing screening and degritting
treatment before combining and passing forward to two separate primary sedimentation streams.
While primarily used to dewater fine materials, it can be used for degritting
, desliming, rinsing, scrubbing and washing.
One year after start-up of the centrifuges, the plant began to operate with the primary solids degritting
and grinding facility.
The crushed ore is then subjected to primary and secondary scrubbing and degritting
. Linatex double-deck banana screens are used to separate - 1-mm reject material prior to treatment in the heavy media separation (HMS) plant.
