Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many ...

The aim of this research is to prepare leady oxide with high specific area for leadacid batteries by a new production process. Leady oxide is produced by a cementation reaction in wt% HCl solution using a pure aluminum or a magnesium rod as the oxide prepared in this process is much superior to Bartonpot or ballmill oxide in terms of physical characteristics.

Lead oxidelead mixtures used in the making of the plates for lead storage batteries have been manufactured for many years by two different processes. One such product has been made by an attrition procedure in which solid pieces or chunks or metallic lead are tumbled in a ball mill or drum through which a stream or air flows.

On the other hand, a more dense oxide is required for the plates of industrial batteries. Thus, it would appear that an oxide milling plant should be used in the former case, and a Barton plant in the latter. Nevertheless, the major battery manufacturers in continue to employ mill oxide for both types of batteries.

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.
