Gilson Testing Screens are ideal for particle size determinations on large samples of aggregate, slag, ores, and other coarse materials. Batch sizes up to one cubic foot (0.028m³) or more can be processed into six fractions in as little as three to five minutes, depending on material type. Vibration and amplitude characteristics are fixed at optimum for mineral aggregates in the 4in (101mm) to No.4 (4.75mm) size range, but options and accessories are available for testing finer samples or special materials. TS-2 Gilson Testing Screens secure the screen trays with manually operated screw-type clamping handles. This model is cost-effective but slightly more labor-intensive for continuous use. A total of six tray slots hold five Screen Trays plus a Dust Pan. Hydraulic conversion kits are available to convert existing TS-2 models to hydraulic clamping TS-1 units.
