The oxide particles are usually round or spherical m shape, and are all less than 60 pin in size with a mean diameter of34pm By contrast, ball mills yield an oxide with 60 70 wt.% PbO, an apparent density of g cm3 and an acid absorption of around 200 mg HZS04 per gram of oxide. The oxide particles are flat and nonuniform in shape.

Barton pot: A fine stream of molten lead is inserted into a heated vessel. Each droplet reacts with the air to form an oxide layer, giving 70 85% lead oxide. Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 80% lead oxide.

Foremost among these was the range of ball mills for battery oxide production. Historically, Chloride was a company with a strong preference for ballmill oxides typically containing about 60 65 wt.% PbO. The range of oxide plants was, therefore, of this type and the company's factory processing technology was organised to match this PbO level.
