Injection Molding: Fill Based on Volume, Not Weight | Plastics Technology
No easy answer here. Somewhere between 90 to 99.9% full—based on volume, not weight. Factors that influence this are the type of part, number of cavities, balance of filling, a weld line at the end of fill, a living hinge, etc. Bottom line for 99% of parts being molded: The first-stage part (s) should be visibly short, not full with sink.

How much resin do I need? – How much resin to mix?
That means the volume of the bangle is 8.84 cubic inches minus 4.057 cubic inches which equals 4.783 cubic inches. Since 4.783 cubic inches equals 78.38 milliliters (4.783 x 16.3871), divide that number by 30 and you get approximately 2.6 ounces of resin needed for your project. You can also use the free resin calculator to do the math for you.

Mill (grinding)
Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Mill Steel Charge Volume Calculation
We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or

The working principle of ball mill
The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.
