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 device and size-control cyclones.

The diameter of a ball mill has a great influence on the power consumption of the mill and thus on the possible production output. This is because the ratio of the diameter to the grinding path length determines the residence time of the material in the mill and thus the theoretically achievable fineness of the material at the discharge.

some years to produce the perfect metal ball, he made the breakthrough in 1883. He developed the first "ball mill", initially to produce better balls for use as bear-ings in bicycle axles. He was soon able to improve the first machine, and called it the "ball milling machine". It formed the basis for another invention, which still

In a further embodiment of the stirred ball mill (FIG. 4), the stirrer has a plurality of arms 15 which are disposed in a staggered arrangement along the stirrer shaft 9 and the container circumference and have paddlelike stirrer elements 16 whose surfaces are in correspondence with the gaps-in between or are in partial overlap.

The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.

The performance test on the fabricated ball mill for the aluminum in powder form and blended with alumina shown proper distribution through scanning electron microscope images for different weight percentages of alumina. The ball mill is used for different speed, time conditions and conditions with the capacity of 250gms can be operated. REFERENCES

Ball mills are often used as secondary grinding mills and for regrinding of middlings in concentrators. Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve.
