Tubular ball mills ride on steel tyres or are supported at both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronous motors that operate through an air clutch or gear system. The girth gear is usually located at one end of the mill but ...

1. Introduction. The material content of a ball mill can be defined either as powder filling or as material holdup. Powder filling is the fraction of the total volume of interstices between balls at rest inside a mill filled with powder (Austin et al., 1984).Material holdup, on the other hand, is the mass content of powder or slurry inside a mill depending on whether milling is done dry or wet.
