Tumbler Screening: the GKM Difference

Gentle 3D motion · precision cuts from 20 µm to 25 mm

Tumbler screening is what sets GKM apart. The KTS reproduces the motion of hand sieving: a gentle three-dimensional tumble at 1.3–1.8 g instead of the 3–6 g hammering of conventional vibratory screeners. Fine, friable, and hard-to-screen products stay intact, blinding drops, and cut precision holds: up to six decks and seven fractions from a single machine.

  • Gentle on friable & fine powders: less degradation, less dust
  • Precision classifying, 20 µm – 25 mm, up to 7 fractions
  • Higher screening efficiency at lower g-forces
  • Proven on the products vibratory screeners struggle with
