The Economy 8" Sieve Shaker is a portable 8in (203mm) sieve shaker that is designed to outperform comparably priced equipment. This 1/4hp unit is widely accepted by state transportation departments for highway materials testing. Back and forth lateral motion is combined with up and down and tilting motions causing test material to travel in an orbit on the sieve surfaces. This assures full use of sieve mesh area without precise leveling of the shaker.
The Economy Sieve Shaker is recommended primarily for No.4 to No.200 size range, but may be used with larger material sizes when specifications for sieve loading and sample quantities permit. The Shaker holds six full-height sieves with pan or thirteen half-height sieves with pan. Clamp bar with attached cover secures sieves. Freestanding operation is normal, but they may be mounted via holes provided in bottom end flanges. This model uses a 15 minute mechanical-electrical timer with an adjustable knob-stop for improved repeatability and a "hold" feature for continuous running.
Motor and all mechanical parts are enclosed in a sturdy metal case.
