Orbital Sieve Shakers

A sieve shaker automates the agitation of particles to deliver precise particle separation and size distribution for a wide range of materials — essential for meeting strict quality control and quality assurance requirements. Compared to manual methods, orbital sieve shakers offer superior consistency, accuracy, and repeatability, helping to eliminate operator variability and ensure reliable test results. Plus, automated shaking dramatically reduces testing time, improving lab efficiency without compromising precision.

Forney’s Orbital Sieve Shakers combine lateral, vertical, and tilting motions to create an orbital action that maximizes exposure of particles across the entire sieve mesh surface. This advanced motion ensures full utilization of sieve area, rapid separation of size fractions, and highly repeatable results in particle size analysis of aggregates, soils, and other granular materials.

Our orbital shakers are designed to handle common testing ranges, including No.4 to No.200 (4.75mm to 75µm), and accommodate both full-height and half-height 8-inch (200mm) sieves. With rugged steel construction, easy-to-use clamping systems, and options for either 115V or 220V operation, Forney’s orbital sieve shakers are trusted by laboratories, contractors, and DOT agencies across the country.
