Gravity Discharge Ball Mills India

Mineral processing Wikipedia

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces such as centrifugal forces magnetic forces buoyant forces one of which is resistance to motion drag force by a viscous medium such as heavy media water or less commonly air
