Conveyor Safety and Preventive Maintenance - …

Misalignment is either quantified mathematically or compared to some general rules of thumb for quick and easy results. Angular misalignment is quantified into a real value by measurements. The actual angle of misalignment is defined by the difference in clearance between the straightedge or string and the outside surface of the sheave or sprocket across the diameter.

Understanding Conveying Velocities | Donaldson …

Because the design air volume is now trying to be pulled through a smaller cross sectional area, the air velocity would have to increase through that section of duct to maintain the design flow. If the fan has the static capacity to overcome the additional energy restriction related to a higher velocity, the section of the duct may experience increased abrasions as a result of the higher ...
