#### Rod Mill Design Calculations

EF1 Dry Grinding for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced. The inefficiency factors for open circuitHow to Size a Ball Mill -Design Calculator & Formula, 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). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to

#### Calculating required diameter of rod to support a given

Aug 15, 2018· Hi! Trying here to calculate the diameter d required of a length L=800mm solid steel rod, supported at both ends which needs to safely hold W 2000kg (19620N ) at the centre. Details of the rod ( structural steel ), taken Modulus of elasticity E at 200Gpa and Yield Strength σ at 250Mpa Using moment of inertia I = (πd^4)/64 Maximum stress σ = yWL/4I.AMIT 135: Lesson 8 Rod Mills Mining Mill Operator Training,Under given load and particle size requirement, capacity is a function of mill length and diameter: Q = kLD 2+N. N is related to mill diameter which decreases with larger diameters k a constant equal to Ï€ /4.

#### 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. For difference between new and worn liners increase power draw by 6%, and adjustTubular Rod Mills ScienceDirect,Jan 01, 2016· The design characteristics of industrial rod mills are similar to ball mills. Most rod mills used in mineral processing are of the overflow discharge type as illustrated in Figure 7.2a. Centre peripheral (Figure 7.2c) and end peripheral discharge mills (Figure 8.1) are also in use.The feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders.
