Elutriation - Wikipedia

Elutriation is a process for separating particles based on their size, shape and density, using a stream of gas or liquid flowing in a direction usually opposite to the direction of sedimentation. This method is mainly used for particles smaller than 1 μm. The smaller or lighter particles rise to the top (overflow) because their terminal sedimentation velocities are lower than the velocity of ...

An MSDNet with six intermediate classifiers are used, and the three main components, multi-scale feature maps, dense connectivity, and intermediate classifiers, are removed one at a time. If all the three components in an MSDNet are removed, a regular VGG-like convolutional network is obtained.

The fine print in FL's REFLUX Classifier technology ...

Large, high-density solids quickly sink and settle in the mixing chamber in the middle section of the classifier, forming a fluidised bed of dense material. This bed is created by a series of water jets at the base of the mixing chamber and rejects any trapped lighter particles.

Classification and centrifugation | FL

Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium. ... Classifiers Material classification can be achieved through a number of methods ...

Dense Medium Cyclone Principles - Portaclone

The less dense material, due to the action of the drag force, settles more slowly. This material is captured in the upward flow of the reverse vortex and exits through the overflow. The medium density at which the separation between more dense and less dense material occurs is called the cut point density.

Classifiers | Article about classifiers by The Free Dictionary

The pulp density (the mass content of the solid phase in the pulp) is the most important method for the operational control of the classifier. With an increase in the density, the size of the particles passing into the overflow increases (since the speed at which they fall decreases in a viscous, dense medium).
