NOVELTY - Continuously producing paste for continuous production of pasted battery plates comprises reacting particle lead oxide, water, and sulfuric acid in an elongated mixer having a mixing to conveying ratio of 65:35 to 80:20 with controlled reaction temperature for an exit product temperature above 60degreesC to 80degreesC.    USE - For continuously producing paste for continuous production of pasted battery plates for lead-acid battery systems.    ADVANTAGE - The continuous process permits uniform distribution of fibers of increased length with different fiber diameters and increased concentration to suit the application. Uniform distribution of fibers in a paste mix avoids clumping of fibers which could result in costly downtimes, while enhancing the strength and life of battery plates. The paste has uniform fluidity with controlled maximum particle size, and the ability to paste grids more uniformly with improved weight tolerances. The mixing process enables reduction or elimination of flash cure times and reduces or eliminates the flash cure process temperature with a reduction of the duration of curing process for finished pasted plate.    DETAILED DESCRIPTION - Continuously producing paste for continuous production of pasted battery plates involves feeding particulate lead oxide to an elongated reactor mixer having mixing paddles and conveying paddles in series. Water and sulfuric acid are continuously injected to the lead oxide in the reactor mixer. The sulfuric acid is rapidly mixed and reacted with the wetted particulate oxide to form a mixture for passage through the elongated reactor mixer for a controlled retention time in the reactor mixer under predetermined mixing and conveying conditions where the mixture is subjected to a ratio of mixing to conveying in the reactor mixer of 65:35 to 80:20. The temperature of the mixture of lead oxide, water and sulfuric acid is controlled as it passes through the elongated reactor along the length of the reactor mixer for a maximum exit temperature of a discharge product in above 60degreesC to 80degreesC (preferably 68-79degreesC) where the rate of reaction of the sulfuric acid with the lead oxide for the production of lead sulfate and the particle size, homogeneity, consistency, density, plasticity, and porosity of the reaction product are controlled. The controlled retention time in the reactor mixer is 30-45 seconds. The mixer is operated in 100-150 RPM. Polymers fibers, glass fibers, or cellulose fibers are added with the lead oxide in up to 0.6 wt.% of the lead oxide for uniform dispersion of fibers within the paste. At least one of carbon powder, activated carbon powder, graphite powder, graphite flakes, or graphite spheres is added in up to 6 wt.% of the lead oxide for uniform dispersion within the paste and has a homogeneity distribution comparable to 3 sigma Normal distribution. The temperature of the mixture as it passes through the mixer is controlled to produce an exit temperature of the discharge product of 79degreesC. Seeding the particulate lead oxide feed is performed with tetrabasic lead sulfate where the discharge product contains tetrabasic lead sulfate crystals. INDEPENDENT CLAIMS are included for:    (1) a battery paste having a maximum particle size less than 1.52 mm and a lead sulfate crystal size of 2-5 microns in tribasic form;    (2) a lead acid battery having battery electrodes pasted by the continuously produced battery paste; and    (3) a reactor mixer.
