Stirred Mills have been proven to provide energy savings compared with traditional ball mills The finer the product required, the more efficient stirred mills will be than a ball mill The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machin
The deviations in the velocity profiles can be explained by the increase in turbulent mixing during vertical migration periods Comparison of observational data to the model results was complicated by physical factors such as tides, Florida Current meandering, etc, which may have a stronger effect on current velocity profiles than DVM
The conveying air velocity profile in a vertical pipeline is exactly the same as that for horizontal flow shown in Fig 24 If the conveying air velocity is too low for the larger and higher density particles, they will drop out of suspension and fall back through the flow This process is known as choking In a vertical pipeline, however .
