Abstract
A stationary horizontal cylindrical reactor for the production of lead oxide utilizes 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 preheated reactor chamber is supplied with raw lead, air and water, and the use of the entire reactor chamber-blade interface as a reaction zone results in a highly energy efficient and high rate production process. The process 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.
