Rod Mill Design & Power Draw. The following equation is used to determine the power that a rod mill should draw. The Bottom Table lists many of the common size rod mills giving speed, loading and power data. The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length.

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 The % loading or change …
The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.
Remember, she determined that the rod will be hung 104 inches from the floor. She subtracts 2 inches that the drapery rings will occupy below the rod and adds a modest 3-inch puddle, so her draperies need to be 103 inches long (104 – 2 + 3). To summarize: The window is 54 inches wide, including the window frame. The rod is 102 inches wide total.
Calculate Ball Mill Grinding Capacity Oct 15, 2015 A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners).

By inserting formulas (1) and (2) into (3) followed by transposing the variables, a formula for the weight F x of the discharge belt 5 is achieved. If the weight F x of the discharge belt 5 with empty discharge belt 5, i.e., without milled material is known, said weight can be subtracted from the calculated value for F x for a discharge belt 5 ...
2 / DESIGN GUIDE 1, 2ND EDITION / BASE PLATE AND ANCHOR ROD DESIGN The vast majority of building columns are designed for axial compression only with little or no uplift. For such col-umns, the simple column-base-plate connection detail shown in Figure 1.1 is sufficient. The design of column-base-plate
If a nut is not fully engaged with an anchor rod (see Figure 2) and the required tension is less than the rod's full allowable, then there are design methods that can be used to evaluate structural adequacy.

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.
