Pipe Trunnion or Dummy Support and Their Stress Calculation
The load-bearing capacity of trunnion supports is usually less and not as comparable to civil structural supports. So, every pipe stress engineer must check the weld point from a failure viewpoint and investigate the ability to carry the piping load (mostly the tangential and longitudinal load and corresponding moment). The chances of weld failure increase …

Ball Mill Circulating Load
As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...
