Lead Oxide Manufacturers

Lead Oxide

Gravita India Ltd is the largest Lead Oxide Manufacturer in India. Since 1992, we have been providing top-notch quality to our clients and supplying globally. The Greyish color Lead oxide is also known as lead sub oxide, grey oxide, battery oxide. The Grey Oxide is produced in the ball mill plant & the process is an endothermic reaction. The chemical formulae of Lead suboxide are (2PbO.Pb). The Lead suboxide is used extensively in the preparation of plates in Lead Acid Batteries.

Lead Oxide Manufacturing Process

Lead 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 the temperature of oxide is increased to control the temperature within the range of 115 to 135OC. The ball mill is cooled with the constant flow of air and also with the water spraying system controlled through a solenoid valve. The Grey Oxide is harvested through a high-efficiency cyclone classifier, bag-house filtration unit, and induction draft fan arrangement. It is in a grey powder form. The desired particle size and free Lead content are ensured through proper plant configuration and precise control of ID Fan suction. Our plants can produce up to 350 mesh size LSO powder.
