A shale shaker comprising
- a basket for holding screen assembly apparatus,
- screen assembly apparatus for treating fluid introduced to the shale shaker,
- a roller bed assembly secured above the screen assembly apparatus, the roller bed assembly having a plurality of spaced-apart rotatable rollers, the fluid initially introduced to the shale shaker onto the roller bed assembly,
- wherein at least one roller of the plurality of spaced-apart rotatable rollers has a central cavity therein, a plurality of holes extending from the central cavity to an outer surface of the at least one roller, and
- fluid movement apparatus in fluid communication with the central cavity for pumping fluid into the central cavity and out from the roller through the plurality of holes.
