Mining Ball Mill Initial Charge Calculation

Home › mining ball mill initial charge calculation. Bond Tests SGS . 2 days ago · Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills . Various correction factors may have to be applied. The test is a closed-circuit dry grindability

Ball Size as Initial Charge Commercial ball sizes 10 – 150 mm Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F

13/02/2017· The power calculated on using equation 1, (Bond, 1961; Rowland and Kjos, 1978), relates to: 1) Rod milling – a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.

Contact. - Ball charges: This calculator gives the surface and the average weight of the ball charges. It gives also a rough interpretation of the ball charge efficiency: - Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs): -Modification of the Ball Charge: This calculator analyses the granulometry of the,

02/08/2013· To accelerate the math or calculation you can use the shortened formula:Dm <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single-sized balls and not a mixture without consideration for ball wear.

torque mill test is the mill energy input divided by the solids load. The energy specific cumulative grinding rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be

was to locate the variation of ball filling in the mill. Ball Charge Program Abrasion In this section, ball abrasion was calculated via manufacture`s ball charge program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion,

The effect of mill charge is primarily through the shifting of the center of gravity and the mass of the charge. As the charge increases the center of gravity moves inward. The power draft is more or less symmetrical about the 50% value. A simple equation for calculating net power draft is P 2.00 3 cD 2.5 m LKl kW (8.12) Kl is the loading factor which can be obtained from Figures 8.5
