Lead Powder Mill - Lead Acid Battery Manufacturing

In the ball mill, Lead is converted to Lead Oxide, by grinding and oxidation process, which is an exothermic process. In this process, heat is generated and temperature of oxide is increased, to control the temperature with in the operating range of 115 to 135C, the ball mill temperature is controlled with constant flow of air and with the water spraying system controlled through solenoid valve.

01-07-2000  The free-lead particles are elongated (or flaky) in ball-mill oxide, but roughly spherical in Barton-pot material. The greater surface area of the free-lead particles in ball-mill material increases the rate of secondary oxidation during storage. Ball-mill oxide provides plates with greater mechanical strength and higher initial electrical capacity.
