Lead Sub- Oxide Gray

Following steps are taken in our organization regarding to Safety, Health and Environment.
  Gold Star Power Limited is one of the largest manufacturers of the quality Lead Sub Oxide in India, The Grey color Lead oxide is also known lead sub oxide, grey oxide and battery oxide. The Grey Oxide is produced in ball mill plant & the process is an exothermic reaction. The chemical formula of Lead sub oxide is (2PbO.Pb).

  Grey Oxide is using on an extensive scale for preparation of plates in Lead Acid Storage Batteries which requires production to strict specifications. Refined Lead (99.98% purity) ingots are the essential input for our manufacturing plant, which is using in the ball mill process.
  It comprise of a small Lead Melting Furnace, operating in line with a hemispherical ball-casting machine, which feeds the balls to the ball mill .In the ball mill, Lead is converted to Lead Sub Oxide in an exothermic process, in conditions of a controlled temperature range and constant airflow. The Grey Oxide is harvested through a high efficiency cyclone, bag-house filtration unit and induction draft fan arrangement. It is in a gray powder form. The desired particle size and free Lead content is ensured through proper plant configuration and precise control of ID Fan suction .Our Plant can produce up to 325 mesh size LSO powder, be configured for any desired production capacity and come complete with the required accessories and material handling systems. We can provide the below range of Grey Oxide.
