The paper presents tests of lead oxidation in a Barton reactor with a capacity of 1200 kg PbO/h, divided into two series. The first series was carried out in conditions of high humidity of the air supplied to the reactor (59–61%), and the second series in conditions of low humidity (19–21%). The study used lead of various purity Alloys can be prepared by using different equipments such as, attritor, planetary mill or horizontal ball mill. The working principle for all these techniques is same. During alloy formation using ball-mill, two processes simultaneously occur: (a) fracturing, and (b) cold welding of powders. Thus, it becomesModule-7 unit-3 NSNT Module 7 Ball-milling
