A material separating system is disclosed having one or more pendantly supported tables with head motion devices for imparting reciprocatory motion to each of those tables to separate material mixtures supplied to the tables into at least two fractions in accordance with the specific gravity of the materials so that one fraction includes particles essentially all of which have specific gravities above some predetermined value while the other fraction particles are substantially all below that predetermined specific gravity value. Associated with each vibrator and the table or tables reciprocated by that vibrator is a remotely actuable device for modifying the attitude of the table or tables and therefor also the predetermined specific gravity value. This actuator is effective to change the pendant support of the table or tables under the control of a controller unit which may simultaneously actuate a plurality of the remotely actuable devices so as to change in unison the specific gravity values for each of the tables to which it is connected.
