Measuring a bulk solids wall friction is critical to ensuring reliable flow.The wall friction angle for a given bulk materialwall surface combination is calculated from the results of a wall friction test.From this angle, the hopper angle required to ensure mass flow is determined.Hopper shapes such as cones and wedges, are determined.By the way, the tangent of the wall friction angle is.
Diagram 1 shows how friction changes, as a function of speed, in a bearing with a given lubricant.Four zones are distinguishable zone 1 boundary lubrication condition, in which only the asperities carry the load, and so friction between the moving surfaces is high.Zone 2 mixed lubrication condition, in which a separating oil film carries part of the load, with fewer asperities in.
