Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement ...

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

1. Introduction. The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles.

More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25% of total ball weight. If the quantity of charge is very less then milling balls will ...

- Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs): - Modification of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill efficiency:

Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e.,
