    By this way the maximum size reduction is effected by the impact of particles between the balls and by attrition between the balls. After the suitable time the material is taken out and passed through a sieve to get powder of the required size. 18. Low speed High speed Correct speed. Working of ball

    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),

  • Ball Mills

    A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral
