ABSTRACT:
A stationary horizontal cylindrical reactor for the production of lead oxide comprises a series of horizontal rotating blades to promote and maintain the oxidation reaction, to provide a particle size reduction and to effect centrifugal classification of the lead oxide produced in the reaction. The reactor includes a chamber supplied with raw lead, air and water, and by the use of the entire reactor chamber-blade interface as a reaction zone results in a highly energy efficient and high rate production apparatus. The apparatus is extremely versatile and can be used to produce low free lead (less than 1%) litharge (PbO) and high free lead or leady litharge on a consistent high volume basis.
