When ordering concrete from a redimix supplier, the concrete comes in cubic yards. If you tell the Dispatcher your dimensions and thickness, he can figure the concrete for you as well. It''s important to accurately calculate the amount of cement, "oops", concrete for a project because it''s very expensive to buy from a redimix company.
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. The % loading or change volume can then be read off the graph below or ...
To find the percentage of a slope, use this slope percent formula: Slope Percent = (Amount of Rise / Amount of Run) x 100. Example: The angle percent of a slope with rise of 6 units and run of 10 units is: Angle Percentage = (6 /10) x 100. Calculated out this gives an angle percentage of 60%.
