Proportioning "A" & "B" to the 30% total charge (6% balls and 24% coarse ore): (6 ÷ 30) x 343. 10 = 68.6 (24 ÷ 30) x 181.43 = 145.1 Totaling the two gives 213.7 lbs. per cubic foot net at 30% total charge. (See Figure 4a for 30% charge). It can easily be seen that at 29% or any other charge the net charge density will change.
Each kilogram of (EN Standard) dry wood contains 5.14 kWh of "potential heat" so 1 kWh of energy is contained in (1/5.14=) 0.195 kg of wood. If your wood heater's Gross Efficiency was (say) 70% then the actual amount of wood that you would need to produce 1 kWh of heat is (0.195/0.70=) 0.279 kg.
grinding rate of coarse material (t/kWh) (2) Production rate, mill power and CSE can be measured during a plant circuit survey. The mill grinding rate of coarse material is then ... 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill
Power drawn at the pinion is 448 kW, 13.617 kWh/tonne (SAG mill) and 570 kW, 17.325 kWh/tonne (ball mill) when processing 32.9 mtph, for a total of 30.942 kWh/tonne or 14.6% above the conventional estimate. A ball charge volume which is lower than those tested has been selected in order to minimize wear.
Aidan Giblet and J. Seidel published a paper on the 2011 SAG conference (MEASURING, PREDICTING AND MANAGING GRINDING MEDIA WEAR) and they obtained Ball Mill Media (kg/kWh) = 0.0817x (Ai)0.498 the two equations are very similar. Two or three groups of people are finding updates to the Bond equation in different places using different data …
