Our Orbital Sieve Shakers are portable, easy-to-use, and outperform comparably priced sieving equipment. They are widely used in particle size testing of mineral aggregates and for sieve gradations of many other free-flowing granular materials.
These cost-effective 1/4hp units feature a back-and-forth lateral motion combined with up/down and tilting actions. The combination of actions moves the test specimen in an orbit on the sieve cloth. Particles are exposed to the entire mesh area of the test sieve, and size fractions are quickly separated.
