Comparison of Barton-pot and ball-mill processes for making leady oxide ...
There are two principal methods of making leady oxide for lead/acid batteries. These are: (i) the Barton-pot process, which utilizes the oxidation of molten lead; (ii) the ball-mill process, which employs the oxidation of solid lead. Several conflicting claims have been made for the advantages of the one process over the other, and vice versa.

Lead Screws vs Ball Screws: It's All about the Application | Helix ...
The basic difference between lead screws vs ball screws is that a ball screw uses ball bearings to eliminate the friction between the nut and screw and lead screws do not. The screw and nut on a ball screw have matching helical grooves that allow ball bearings to re-circulate in those races, and are typically semi-circular in shape to accept ...

Lead Screws vs Ball Screws: It's All about the Application
The screw and nut on a ball screw have matching helical grooves that allow ball bearings to re-circulate in those races, and are typically semi-circular in shape to accept the spherical ball bearing. Lead screws use deeper helical threads and a mating nut, which is usually made of a polymer composite or bronze.

Lead/acid batteries
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.
