Our founders, Sutton Steele & Steele, invented the first dry materials separation equipment, known today as "density or gravity separators, air tables or fluidized bed separators". Originally developed and patented in 1919, the density separation is achieved with two components, mechanical vibration and air fluidization.

The fine sand or stone particles, if not eliminated through the sand screen, will not be rejected with heavy fraction, but will go on to the mill with the grain. Recovery of these finer particles of heavy reject material could be better with a Fluidized-Bed-Separator, which would return them with a middling fraction for re-screening.
The product processed by the gravity separator is separated into layers of different specific weight according to the "fluid bed" principle. The size of the kernels is normally between 0.5 mm (fine …

Zircon sand beneficiation is the process of removing impurity minerals in zircon sand ore and increasing the content of zircon sand. The commonly used zircon sand beneficiation process is a composite beneficiation process, including gravity separation, flotation, electric separation, magnetic separation and other different …
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, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
Sand separator, type NSS: Specific wastewater streams, sand and sediment from settlers and flotation units can be automatically removed and concentrated by the sand separator. Oil & water separator, type CPI: Operates by using gravity to separate oils from oil contaminated streams in a concrete basin.
Gravity separation of bastnaesite has also had limited economic success. [Citation 66] However, gravity separation has been employed for REM beneficiation in heavy mineral sands processes, with separators such as FC, Knelson, Mozley Multi-Gravity Separator, spirals, and shaking tables serving as gravity pre-concentration …
Air or pneumatic table (Fig. 9 b) is initially the most common dry gravity separator. This dry table uses the similar motion to wet shaking table.

Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
