METHOD AND APPARATUS FOR CONTINUOUSLY MIXING BATTERY PASTES

摘要

A process and apparatus for continuously mixing and applying paste to bat tery grids for use in lead-acid battery systems, in which particulate lead o xide, water and sulphuric acid are reacted in an elongated mixer having a mi xing to conveying ratio of about 65 : 35 to 80 : 20 with controlled reaction temperature for an exit product temperature in the range of above 60°C to a bout 80°C. Additives including reinforcing fibres can be added in an amount up to 0.6 wt% of the lead oxide and carbon and graphite powder can be added in an amount up to 6 wt% of the lead oxide.
