The different bases of measurement are not interchangeable. For the crash stop example above, the filling is 139.2/763.3 = 18.2% as a proportion of the total mill volume, compared to the cylindrical section filling of 19.3% using Eq. (5). Table 2 compares the filling results for both the crash stop and grind out using the two calculation methods.

crash stop. The mill filling should be measured at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out

May 09, 2019. by GCP Applied Technologies. Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up ...
