Testing screen

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 (28.3L) or more can be processed into six fractions in as little as six to ten minutes, depending on the 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. Testing Screen models have the same performance characteristics but differ in the clamping mechanism, safeguarding devices, number of tray slots, and operational convenience features.

The drive mechanism is completely enclosed for added safety, and the powerful 1/2hp capacitor-type motor is operated with a starting switch with built-in overload protection. Independently removable Screen Trays and Dustpans are purchased separately and shared by both Testing Screen and Test-Master® models. The Trays have replaceable Screen Cloth and are available in a wide range of opening sizes with ASTM E11 and ISO 565 specification cloth or punched steel plate.

Gilson Testing Screens are designed to be securely bolted to a concrete or rigid floor system. They feature a manual hydraulic pump for easy tray clamping, a top-mounted, enclosed drive mechanism, and a 1/2hp capacitor motor with overload protection for safe operation. Both the TS-1 and TS-3 models offer a simple On/Off switch.
