Erosion versus velocity

Figure 4-127. Data categories involved in erosion research are plotted as erosion versus velocity.

Corrosion, erosion, and power consumption versus tube veloc-ity. 

The approach taken here is to employ standard materials characterization tests to measure the materials properties of the granulated product. With this information, the mechanism of attrition, i.e., breakage versus erosion, is determined. The rate of attrition can then be related, semi-empirically, to material properties of the formulation and the operating variables of the process, such as bed depth and fluidizing velocity.
