Morebond mill power equation piercarlofoddis. Operating work index is not the specific energy consumption, 24 Oct 2018 Specific Energy Consumption is the power draw of a mill (kW, usually The Work Index is a fitted coefficient to Bond's equation given in theGeometallurgical estimation of comminution indices for, The bond ball Mill Work Index provides a measure of energy required to grind a Crusher

MoreBond s law for crushing mills-Henan Mining Machinery Co., Ltd. A crushing law proposed by Rittinger in 1867 states that. CHE F313: Separation Processes II Bond's Law • A somewhat more realistic method of estimating the power required for crushing and grinding was proposed by Bond in 1952 • Bond postulated that the work required to form particles of size D p from very large feed is

MoreA material constant which is a factor used for power calculations, expressed in N/mm2. Machining time, T c (min) Machining length (l m) divided by the table feed (v f).

MoreThe basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

MoreIt is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n where n = 0.3 to 0.5. It is evident that mill power is a function of the height at which the media is lifted and the density of the media, i.e., PM = K Ï b LD 2.5 where k is a proportionality constant.

MoreJan 01, 2016· In Bond’s equation (Equation ), the grinding energy, E G, required for size reduction of rocks in industrial tumbling mills was based on mill shaft power, P M, and on mill capacity (Q). The relationship between these parameters is (3.6) E G = M i l l P o w e r M i l l c a p a c i t y = P M Q

MoreThe Rowland and Kjos equation indicates that power draw is a function of the fraction of the critical speed for the mill. Bond quantified the rod mill power draw as a function of the Work Index, capacity, and a series of correction factors: PM = Wmtest,i FT Q. FT = F1 F2 F3 F4 F5 F6 .

MoreAs you can see in the Convexity Adjustment Formula #2 that the convexity is divided by 2, so using the Formula #2's together yields the same result as using the Formula #1's together. To add further to the confusion, sometimes both convexity measure formulas are calculated by multiplying the denominator by 100, in which case, the corresponding

MoreThe ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material
