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.

Today, Triple/S’ line of density separators and stoners are being used in thousands of applications, from cleaning of leafy spices and peppercorns to reclaiming copper from scrap wire and cable.
