how to load steel balls into ball mills

Each primary mill contains several 4" steel balls that grind the ore as the mills turn. When the ore is reduced to 3/4" or less, it moves out of the mill in a slurry solution.

The balls (or "grinding media") in a ball mill can be made of anything, but typical materials for ball mill media would be stainless steel balls, lead, glass, or ceramic balls. Wikipedia has a nice cutaway, side view animated .gif of a ball mill in action:

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

The balls are manufactured from high carbon, alloy steel bars and then forged into balls. Balls for use in mineral processing ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels.

Calculation of the power draw of dry multicompartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

Lifters are used to prevent the ball charge from slipping as mass cascades down the mill shell. They also act as keys that project ball charge and keep the layers of balls next to the shell, moving around with the shell. Increasing lifter height reduces effective mill volume and increases the likelihood of cataracting.

Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls and steel balls.

Ball Mill. However, most Ball Mills operate at speeds between 65 and 75 percent of critical speed. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.
