An overfilling indicator for wet overflow ball mills
01.09.2016· For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw; rather more often the opposite. This is attributed to the fact that the slurry pool on the opposite side of the rising ball media would counter the torque required to rotate the mill shell and lift the ball media, leading to a decreased
An overfilling indicator for wet overflow ball mills
A database consisting of 121 sets of industrial overflow ball mill surveys worldwide was used to establish the pattern of the slurry residence time in the full scale operational overflow ball mills. According to the pattern, the residence time thresholds beyond which overfilling a ball mill is likely to occur were defined. For a ball mill with an internal diameter smaller than 5.9 m, the

Grid Type Ball Mill VS Overflow Type Ball Mill, How to
The overflow ball mill discharges the ore by the gravity flow with the slow speed, so its production capacity is relatively weak, and because the material stays in the ball mill for a long time, it is easy to cause the overgrinding phenomenon. 3. According to the grinding effect. The steel ball inside the grid type ball mill is added in proportion. When the steel ball in the ball mill is
Comparison between Overflow Ball Mills and Grid Ball Mills
Overflow ball mills belong to high level ore discharge. By contrast, the finegrained particles of grid ball mills are discharged by grid plate, which belongs to low level ore discharge.
