Lead Sub Oxide (Grey Oxide) :


Lead Sub-Oxide (2PbO.Pb.H2O), also commercially known as Grey Oxide / Battery Oxide is used on an extensive scale for preparation of plates in Lead Acid Batteries which requires production to strict specifications. Refined Lead (Minimum 99.97% purity) is required input for our Grey Oxide manufacturing plant, which uses the Ball Mill process and has below specifications:

ATTRIBUTE COMPOSITION
Color Blackish to Greenish Grey
Crystal Structure Tetragonal
Apparent Density 1.4 - 1.6
Retention on 240 mesh (63 micron) (max %) 0.1
Retention on 325 mesh % 2.0
Water Absorption mg/gm 110-120
Acid Absorption mg/gm 160-200
Free Lead (% Max) 25-40
Lead Monoxide (%) 60-75

Grey Oxide produced in Ball Mill Plant, which comprises of a small Lead Melting Furnace, operating in line with a hemispherical / cylindrical ball-casting machine, which feeds the balls to the ball mill. In the ball mill, Lead is converted to Lead Sub Oxide, which is an exothermic process. In this process heat is generated and temperature of a oxide is increase to control the temperature with in the range of 115 to 135OC we cool the ball mill with constant flow of air and also with the water spraying system controlled through solenoid valve. The Grey Oxide is harvested through a classifier high efficiency cyclone, bag-house filtration unit and induction draft fan arrangement. It is in a grey powder form. The desired particle size and free Lead content is ensured through proper plant configuration and precise control of ID Fan suction. Our plants can produce up to 350 mesh size LSO powder.
