Shaking Table Separation
The table head is driven by a motor and is connected to the table by the pull rod, so that the table can make asymmetric reciprocating motion in the longitudinal direction. When the table is moving forward, its speed becomes faster and then stops rapidly; when it is moving backward, its speed increases rapidly from zero and then slowly ...
