Prudential crown drilling sand pumping:
Drilling and pumping sand pumping vessel working principle: when the motor through a triangle belt, reducer, gear reducer drives the impeller to rotate slowly, the sand with the feed chute into the washing groove, rolling in the impeller drive, and mutual grinding, remove the gravel covered surface impurities, and destruction of water vapor coated layer of sand to for dehydration; while adding water, forming strong currents, timely foreign impurities and the proportion of small away, and from the overflow outlet washing tank discharge, the efficient pumping sand into the cleaning effect. Clean gravel from the leaves away, finally into sand trough from the rotation of the impeller, complete sand cleaning effect.
