Sieve Shaker, 8" with Mechanical Timer (115vac, 60hz)

Forney Orbital Sieve Shaker

Efficient. Reliable. DOT-Approved.

Forney’s Orbital Sieve Shakers deliver outstanding performance in a compact, easy-to-use package — offering superior results at a cost-effective price point. Designed for particle size analysis of mineral aggregates and a wide range of free-flowing materials, these versatile 1/4hp units are a trusted choice for laboratories and state DOTs across the country.

The orbital shaker motion combines lateral back-and-forth movement with gentle tilting and vertical action, creating a true orbit that ensures full exposure of materials across the sieve surface. This effective agitation quickly and accurately separates particle sizes from No.4 to No.200 (4.75mm to 75μm), making it ideal for asphalt, concrete, and soil testing applications. Larger particle sizes can also be accommodated, depending on sample load requirements.

Fast Setup with EZ-Clamp Technology

Simplify your testing workflow with our EZ-Clamp system. This integrated clamping and cover solution lets you quickly secure your sieve stack with a simple lift, slide, and twist — no tools or adjustments needed between tests. When finished, just raise and remove the stack; the clamps stay ready for your next run.

Built for Laboratory Toughness

Housed in a durable, powder-coated steel case with anti-slip rubber feet, the Orbital Sieve Shaker is ready for daily lab work. It operates freestanding or can be securely mounted via built-in flange holes for added stability.

Choose Your Power Option

Models are available for either 115V/60Hz or 220V/50Hz electrical systems to match your lab requirements. (Note: 220V models ship without an electrical plug.)

Sieve Capacity and Timing

This shaker accommodates either six full-height or 12 half-height 8in (200mm) sieves plus a collection pan. A classic mechanical timer provides up to 15 minutes of test time, or select the "HOLD" setting for continuous operation when needed.

Key Features:

• Simulates precise hand sieving action for highly repeatable results.
• Effectively separates material sizes from No.4 to No.200.
• Accepted by numerous state transportation departments for highway material testing
• Easy freestanding use or mountable for secure operation
• EZ-Clamp system for rapid sieve setup and consistent testing
