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 separation effect of heavy medium gravity separation is mainly determined by the density of the ore particles, and the influence of the size and shape of the ore particles is small, so the separation precision is relatively high, the minerals with a small difference in density (such as 0.1 g/cm3) can be well separated.
