Application of the fractal theory for evaluating effects

Dec 25, 2014Momentum transfer efficiency is a function of the inlet pressure to the mill and is associated with the level of turbulence induced, which also strongly depends on the inlet pressure. As an effect of these various factors, the relationship between the pressure and fractal dimension exhibits a diminishing trend, representing energy loss occurring.

Coal Mill Safety

VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is capable of making a system that conforms to these and is therefore safe. However, this is not the case.
