Effect of Surface Roughness on Wall Friction Angle for Various Liners

The design of the bulk handling equipment should be done very effectively. Although the design of this equipment might look simple, it can easily become costly in maintenance if it is not designed properly. A designer should consider parameters like surface roughness and wall friction angle, etc for a better effective design. Considering these parameters in design will not only improve the performance of equipment, but it will also reduce wear and tear of bulk solid handling equipment. The objective of this study is to establish a regression curve between the surface roughness and wall friction angle and to showcase the effect of surface roughness on the wall friction angle.
