THE WETTED LEAD SHOT IS GRAVITATIONALLY FED FROM THE VESSEL OUTLET INTO A MAIN PIPELINE BEING CHARGED WITH THE ORGANIC LIQUID UNDER PUMP PRESSURE TO FLUIDIZE THE LEAD SHOT AND MOVE IT IN THE PIPELINE TO THE CELL HOPPER. A DRAIN IS PROVIDED IN THE HOPPER FOR REMOVING THE LIQUID FROM THE LEAD SHOT, AND AN OUTLET AT THE BOTTOM OF THE HOPPER ALLOWS THE LEAD SHOT TO BE DISCHARGED INTO THE CELL.
