Choosing The Correct Gravity Separation Machine

High G-Force Gravity Concentrators. The higher the G-force, the smaller the minerals you can recover with a given technology. All of the Falcon Gravity Concentrators are high G-Force devices that achieve forces from 100-600Gs. When these forces are applied to a mineral feed, particles as fine as 3 microns in size can be selectively recovered.

Analysis of the operating mechanism of a Knelson concentrator

1. Introduction. Enhanced gravity separators (EGSs) are commonly used for processing fine particles. Unlike conventional gravity separators, an artificially enhanced gravity field (tens to hundreds of times greater than Earth's gravity) is generated by a fast rotating bowl using EGSs, resulting in a drastically augmented sedimentation velocity …

High capacity gravity separators a review of current status

The relatively high capacity of cone concentrators makes them well-suited for scavenging ft~am quantities of valuable, higb-density minerals from adings streams. The operating benefits associated with the capacity of the 2m diameter cone concentrator were capitalised in the development of a higher capacity 3.5m diameter machine in 1980.
