Analysis of the operating mechanism of a Knelson concentrator

In this study, the operating mechanism of a Knelson concentrator (KC) is analyzed by considering the concentration mechanisms of dense minerals obtained based on the feed properties, operating parameters, and design parameters of the KC bowl. The efficiency of the KC is affected by all the studied factors, i.e., the structural parameters of …

An investigation on laboratory Knelson Concentrator …

The retained mass of material in the Knelson Concentrator (KC) bowl depends on the main forces—the fluid drag force (F d), the centrifugal force (F c), and the buoyancy force (F b)—which act on the particles in the concentrating bowl.They are functions of the material properties, as well as the operating condition parameters.

An investigation on laboratory Knelson Concentrator …

The objective of the present study is the derivation of an empirical model of material separation inside the Knelson Concentrator in terms of particle characteristics (size and density) and operating condition parameters (rotational speed and fluidization water pressure, etc.). This model can be used, firstly, to predict the separation of GRG ...

Performance evaluation of processing clay-containing ore in Knelson …

The Knelson concentrator performance was evaluated based on the theory developed by Coulter and Subasinghe (2005). 1.1. Theory. A particle that enters into the Knelson concentrator bowl tends to traverse in a helical path attributing to the forces acting on the particle.
