Sales OnlineNo 1 rod mill/ball mill circuit was operating very efﬁ ciently when comparing the combined operating work indices for both mills with the rod mill and ball mill laboratory work indic Note, in Figure 1, that the rod mill product slope is less than 05 due to an extra amount of nes present being ﬁ ,

Sales OnlineThe end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 314 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (314 * 8) If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the feed calculation

Sales OnlineLater, many other research efforts were made to define the relationship between S i and J under different operating conditions These studies focused on the determination of S i using the grinding kinetic model More specifically, Deniz V and Onur T (2002) investigated the breakage kinetics of pumice samples in relation to the powder filling volume in a ball mill, at J = 20 %, and found that ,
