How to Find the Median Value - mathsisfun.com

To find the value halfway between them, add them together and divide by 2: 21 + 23 = 44. then 44 ÷ 2 = 22. So the Median in this example is 22. (Note that 22 was not in the list of numbers ... but that is OK because half the numbers in the list are less, and half the numbers are greater.)

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.
