Experimental size distributions for coal ground in O98 m LD pilotscale airswept ball mill fitted with a twincone classifier 259 ing to a fractional filling of the mill volume by the bed of balls of J 02 using a formal porosity of 04 for the ball bed 290 lbft3 The dry mass of coal used was 122 g assuming an apparent specificView Details
In addition the amount of powder in a mill relative to the amount of media is usually defined by “The fractional powder filling U is the fraction of the interstices of the mill bed at rest in a packed bed condition that is filled with powder calculated using a bulk density of the powder and assuming that the porosity of the bed is 04 for a bed of balls”View Details
the mill is used primarily to lift the load medium and charge Additional power is required to keep the mill rotating 813 Power drawn by ball semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features of a model for mill powerView Details
Optimization of mill performance by using online ball and pulp measurements Soon after a stop a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples Crash stops are difficult to handle The mill and all feed streams should be stopped simultaneously but often they are stopped around about the same timeView Details
