Screening Machines

Your screening application should be as unique as your screening machine. Not all screening machines are created equal. GQI specs machines from an application perspective. The machine should meet your application, your material, your cut, your throughput, and your process... not the other way around.

Performance Screening

The Ultimate Tumbler Screener

GKM's KTS Model - The Flagship

Most screening problems are motion problems. For fine, friable, and hard-to-screen products, the KTS replaces punishing vibration with a gentle, three-dimensional elliptical motion, tuned on three axes so dwell time becomes an engineering variable. Sharper cuts, higher yield, less reprocessing.

  • Ultra-precise, repeatable cuts
  • Up to 6 decks / 7 fractions
  • Gentle on product & machine: 24/7 duty
  • Quiet (~75 dB(A)), low power draw
  • Dust-tight by design
  • Anti-blinding: ultrasonic, balls, brushes & more

Safety, Check & High-Volume Screening

Control Screeners

GKM KTS-V2 & KTS-VS2

Police incoming material at truck receiving and protect outgoing product ahead of bagging and packaging lines. High-frequency 2D motion with centered product flow delivers safety screening at extreme rates: up to 200 tons per hour through a single machine, with low overall height for tight installations.

  • Up to 200 tph feed rate
  • Mesh from 36 µm, to 20 mm (per model, see the comparison table)
  • 1–2 decks, centered flow
  • Ø 450 – 2000 mm model sizes

Vibratory Screening

GKM KTS-V & KTS-VS

Compact, fast, and flexible. The KTS-V and KTS-VS handle classifying into multiple fractions, dedusting of granules, pellets, and regrind, and wet screening of slurries, with FDA-compliant contact materials, quick screen changes, and dust- & gas-tight modular decks for high-value products.

  • Dry or wet screening on one platform
  • Up to 10 tph feed rate
  • 1–3 decks / up to 4 fractions
  • Mesh from 20 µm to 20 mm
  • Fast on-site remeshing, twin-clamp rings

Laboratory Machines

GKM KTL & KLS

Keep your QC bench on the same technology as your production floor. The KTL digital electromagnetic sieve shaker analyzes fine, dry, powdered, and granular products (dry or wet), stacking up to 8 or 16 standard 200 mm analysis screens with the same three-dimensional movement as production machines. The KLS 200 air-jet lab-sieve handles the hardest cases: ultra-fine and electrostatically charged products, down to 1 µm.

  • KTL: analysis from 20 µm, up to 16 screen decks
  • KTL: 200 / 300 / 400 mm models, wet-capable
  • KLS: air-jet screening, 1 µm – 3 mm feed sizes
  • KLS: rotating air-jet nozzles prevent blinding
  • Delivered ready to operate
  • Interval & timed operation for repeatable QC
