The instrument is powered by an electromagnetic drive which has no rotating parts, making it maintenance free and extremely quiet in operation. The vibratory action produced by the power unit moves the sample all over the sieve in a unique way producing faster, more efficient sieving, while the rapid vertical movements also helps to keep the apertures free from blocking.
