Sweco Round Separators
Open the catalog to page 1. Basically, the Sweco Separator is a screening device that vibrates about its center of mass. Vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. Rotation of the top weight creates vibration in the horizontal plane, which causes material to move across the screen ...

Gravity separation : ALS
ALS provides gravity separation, in combination with other techniques, to identify and optimise the process flowsheet for the target mineral. Gravity separation is achieved based on the difference in specific gravity (SG), shape and particle size of the valuable minerals or metals, as compared with the gangue or host rock and the carrying medium.

Gravity Separation Equipment: Alternatives for Fine Coal ...
Mozley Multi-Gravity Separator. The operating principle of the MGS is similar to that of a conventional shaking table, except that centrifugal forces are used to enhance the separation of fine particles (Figure 2d). In this system, feed slurry is distributed along the inner surface of a slightly tapered rotating drum.
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

A spiral is a curve in the plane or in the space, which runs around a centre in a special way. Different spirals follow. Most of them are produced by formulas. You can make a spiral by two motions of a point: There is a uniform motion in a fixed direction and a motion in a circle with constant speed.
A gravity feed slurry distributor, mounted centrally on top of the spiral module, ensures even distribution of feed to each spiral start. The distributor body is constructed of fiberglass and the wetted surfaces are lined with wear resistant polyurethane. The center mixing column and hoses (not shown) are made of durable and replaceable HDPE ...
