ball mill feed control

  • 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.

    Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill.

  • Ball mill Wikipedia

    In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell.
