The exact type of bowl and balls used depend on the type of material being ground. For example, very hard samples might require tungsten carbide balls in steel bowls. Therefore, the ball mills that we used might not be suitable for grinding coarse salt. But for typical use, agate is a good choice. The fourth factor is the size of grinding media.

Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the
In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media.

This new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar as roll press, roughly 30% to 50% in respect to the ball mill, but with a moderate circulating load and grinding pressure.
the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is
The ball mill operates at higher efficiency when there is an agent (commonly called "grinding aid") present in the mill which causes the formed particles to remain dispersed within the ball mill. Thus, compounds such as lignosulfonates, triethanolamine and the like have been used in ball mill operations.

Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line. Approximately 30-40% of the ball charge will be void space.

Dry comminution technologies, such as High Pressure Grinding Rolls (HPGR) and Vertical Roller Mills (VRM), have been successfully used in other industries such as cement and coal for decades, and the literature claims that these technologies are more energy efficient than conventional comminution practices.
Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...
