Abstract
Abstract PARTICULATE LEAD OXIDE IS DROPPED INTO ONE END OF AN ELONGATED HOUSING THAT CONTAINS ROTATING MIXING PADDLES. WATER IS INJECTED INTO THE HOUSING AT APPROXIMATELY THE SAME LOCATION. THE PADDLES MIX THE WATER WITH THE LEAD OXIDE WHILE MOVING THE MIXTURE TOWARD THE EXIT END OF THE HOUSING. SULFURIC ACID IS INJECTED INTO THE HOUSING AT A DOWNSTREAM LOCATION WHERE THE WATER AND LEAD OXIDE HAVE BEEN MIXED THOROUGHLY. OTHER INGREDIENTS CAN BE INJECTED INTO THE MIXTURE AT THOSE LOCATIONS CONDUCTIVE TO CONTINUOUS PRODUCTION OF BATTERY PASTE HAVING UNIFORM PHYSICAL AND CHEMICAL PROPERTIES.
