Screening

Gilson pioneered the laboratory-scale screening machine back in 1939, and we are still the best option for accurate, efficient characterization of coarse particles up to 6in (152mm).

Gilson Screen Shakers fill the gap between laboratory testing with conventional test sieves, and quality control for large volumes of coarse materials. The Gilson Testing ScreenTest-Master®Porta-Screen®Gilso-Matic®, and Continuous-Flow screening machines are the global standard for separation of large samples and coarse particles, and their durability is legendary. These machines are in use all over the world for gradation testing, classifying, quality control, and even small-scale continuous production of aggregates, ores, slag, coal, coke, and other materials. Screen Shakers are ideal for particle size determinations and quality control of large samples. Gilson screening machines are based on a system of removable screen trays fitted with replaceable wire cloth or round-hole punched plate.
  • Screen Trays from Gilson are available in all sizes of ASTM E11 or ISO 565/3310-1 woven wire cloth.
  • Screen Tray Verification is available to document conformance to ASTM E11 or ISO 565/3310-1 Inspection or Calibration Grade requirements.
