Laboratory Aggregate Screening Equipment & Testing Screens
Choose a Testing Screen for the Sample
Laboratory aggregate screening equipment separates test samples into size fractions using screen trays and controlled agitation. Start with the largest particle, required sample volume and grading sequence. These testing systems should not be selected using the production-rate expectations of quarry screening plants.
Compare the Gilson TS-1 Hydraulic Testing Screen, 6-Tray Gilson Test-Master and Gilson PS-3 Porta-Screen against the sample and installation requirements. Tray count alone does not establish the allowable sample loading or suitable particle range.
Compare Clamping, Loading and Working Space
The TS-1 listing describes hydraulic tray clamping, while the Test-Master listing describes an enclosed configuration with a hopper and timed operation. Compare how each machine is loaded, how trays are secured and how access doors affect the space needed around it.
Check the specified mounting arrangement for the exact unit. The TS-1 requires floor anchoring; do not extend that instruction to every screening machine. Confirm available floor or bench support, electrical supply and operator access before ordering.
Build the Screen Tray and Dustpan Set
Choose tray openings to match the required grading sequence and documented screen specifications. Check frame dimensions and machine compatibility separately from opening size. A round test sieve and a rectangular screen tray with the same opening are not interchangeable.
The TS-1 listing states that screen trays and dustpans are purchased separately. Verify the included items for every selected machine, including whether a dustpan occupies a tray position. Accessories such as the Inclined Chute Pan for Gilson Testing Screens must be checked against the intended system and collection arrangement.
Plan Collection, Cleaning and Storage
The Clean-N-Weigh Accessory and Screen Tray Storage Rack support handling and storage of compatible trays. Confirm the tray format each accessory accepts rather than choosing by the general screening-equipment label.
Review dust-control and sound-enclosure options for the selected model, keeping cleaning access and routine maintenance in mind. Follow the equipment instructions for operation and approved cleaning methods; a cover or enclosure does not replace the laboratory's dust and noise assessment.
Keep Screening and Round-Sieve Testing Distinct
For smaller samples tested in round sieve stacks, compare aggregate sieve shakers and aggregate test sieves. Choose the setup that accommodates the prescribed sample and particle range rather than forcing material into an undersized screen or sieve stack.
