A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
A common design of home ball mill is known as a Sponenburgh Mill or SponenMill for shortafter its designer Lloyd Sponenburgh.

walls as seen in figure 1. A variation is a jar millin which relatively small ceramic containers holding some grinding media are rotated on a common machine frame. It is used for small batches of valuable chemicals and in laboratories. Figure 1. Schematic representation of the crushing mechanism in a ball mill
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an LD ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
The Ball Mill Lloyd Sponenburghin his Ball Milling Theory and Practice for the Amateur Pyrotechniciantells us his explorations into ball milling began when he was faced with having to do all that grinding with a mortar and pestle to achieve small particle size and intimately mix his chemicals. Lloydss book is the most complete and
The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills.
The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameterball mill loadingmilling rate and the type of grinding (wetdry). None of the characteristics of the material being ground have any influence on K 1.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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 device and size-control cyclones.
