Hello, I've been working on another project regarding belt conveyors. Currently, I have a belt conveyor with asymmetric loading, meaning that load will be on one side of the conveyor in some loading cases. Usually, I used crowned pulleys and/ or centering rollers. This would usually solve...

Thanks dvd for an answer. This was exactly what I was looking for.

Thanks You for replies. The first step I want to accomplish , is to correctly size the needed volume of "air box", diameter and amount of holes needed and power of the suction pump. Carton boxes should be held in place, as conveyor travels 15m/min; conveyor is horizontal. Boxes should be held...

Thanks for a reply. We are trying to design and develop this type of conveyor ourselves, not buying it :).

Hello, maybe someone has/ knows some guidelines or a book on designing vacuum (suction) belt conveyor? Belt conveyor should be transporting carton boxes, and there's is a need to "hold " these boxes in place. Any help appreciated. Example below...

Hello, came up with a somewhat stupid problem: been designing steel structures for some time, usually just using analytical formulas for bolted connections + FEA beam analysis. Extracting beam moments, shear forces and designing connection accordingly. Recently, decided to perform an in-depth...

Thanks for the a quick reply. "Are you trying to ascertain mechanical load power requirements via the data from the VFD output" Yes. I'm trying to do that. I'm trying to compare calculations vs measured mechanical power. in other words, how well calculated value correlate with measured results...

Hello, I've been doing data analysis of asynchronous motor under load with frequency inverter. I've got active power and current values exported from the frequency inverter (as .xls file) in one second intervals. My question is as follows: do i need to take into account efficiency of the motor...
