Abstract
The screening motion of a screening machine is changed by adding ballast, while the machine is in operation, to selected closed compartments moving with the vibrating assembly. In the preferred embodiment, the ballast is added through flexible tubing which is inserted through ports that close with spring loaded oil hole caps. When the tubing is pulled from the ports, the caps snap closed to capture the ballast in the selected compartments.
