Vibro Sifter for Minerals & Metal Powders

Mineral processors and metal powder producers use vibro sifters to grade fine materials into specified size ranges and to remove oversize before packing. Typical materials include calcite, dolomite, talc, bentonite, silica flour, cement additives and metal powders such as copper, aluminium and iron.

Applications

Producing fixed-mesh grades of mineral fillers.
Removing oversize from cement additives and construction chemicals.
Grading metal powders for sintering, welding and coatings.
Check screening before bagging.

Selection Points

High bulk density – heavy powders load the screen; size on weight, not just volume.
Abrasion – check screens frequently and keep spares.
Multiple grades – use a double or triple deck.
Fine metal powders can be combustible – consider flameproof construction.

For coarse aggregates and quarry products, large rectangular vibrating screens are normally used. Our circular vibro sifters are suited to powders and fine granules.
