An electromagnetic shaker uses the same principle, but instead, uses the vibratory motion to "shake" a structure – hence the term shaker. A reaction shaker is a shaker where the coil is mounted to a structure or item under test.
enerally used and compact sized apparatus in sieve analysis has 720-7,200 tpm of vibration frequency and 0.1～2.5 mm amplitude. Intermittent duty for uniform and accurate sieving can be selected in vibration 0.1～5 sec. with breaking time of 1sec
