The dehydration sieve utilizes dual-electrode self-synchronization technology and features a universal eccentric block and adjustable amplitude vibration motor. It is mainly composed of the sieve box, exciter, support system, and motor. The two independently connected vibration motors are driven synchronously in opposite directions via a belt coupling. The centrifugal forces produced by the two sets of eccentric masses are superimposed along the vibration direction, with the opposite centrifugal forces canceling each other out, thereby forming a single vibration excitation along the vibration direction, causing the sieve box to perform reciprocating linear motion.
