Back-and-forth lateral motion combined with up/down and tilting actions distribute material across the sieve|Accurately separate particles from size no. 4 to no. 200 (4.75 mm to 75 m)|Precisely time operation up to 99 minutes with the built-in digital countdown timer|EZ-Clamp system quickly and securely locks in sieves for testing|Compliant with multiple ASTM and AASHTO standards|Accepts 8" (200 mm) or 12" (300 mm) test sieves offering great versatility|1 year warranty|Use the orbital sieve shakers for particle size testing of mineral aggregates and for sieve gradation of free-flowing granular materials. The back-and-forth and up/down motions plus tilting action move the testing samples across the entire mesh area of the test sieve to quickly separate the materials. Orbital shakers accommodate from no. 4 to no. 200 material size range but may be used with larger sizes when specifications permit. Shakers feature a digital timer with a large LED display that can be seen from a distance. Use the countdown timer for operations up to 99 minutes with 1 second increment. Timer includes a pause function and user-selectable modes for great versatility. Easy one-button operation and saved settings offer excellent repeatability between cycles. Quickly and easily lock in the sieves using the EZ-Clamp system. The sieve cover slides freely up and down the clamp rods to hold sieves in place. A quick twist of the clamping screws secures the stack in place. All mechanical and electrical parts are enclosed in a rugged painted steel case for safety and durability.|Shaker accommodates 10 full-height or 21 half-height 8" (200 mm) diameter sieves; 6 full-height, 14 half-height, or 10 intermediate-height 12" (300 mm) diameter sieves.
