### Mill (grinding) Wikipedia

A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a

### Ball Mill an overview ScienceDirect Topics

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

### Tubular Ball Mills ScienceDirect

The top ball size is related to the top particle size to be ground, in this case 28.3 mm, by the relationship; ball size (dB) particle size (d) = 4 where the ball and particle sizes are in the form of Stadler numbers. Stadler number = 6.64(log d + 8.07) + 1 where d is in centimeters. Thus the top ball size is 114 mm. Divide the % largest size ball in the optimum charge (column (4)) by the
