What if you want a flighted belt

If you read part 1 of this article, we have mainly focussed on the belt material itself. If you know all of the diameters, then you need to refer back to the belt manufacturer's brochure again because there will be a minimum roller diameter given for each belt material. Some other conveyors use welded on flights or cleats on the conveyor idler manufacturers underside of the belt that uses grooves in the bed and the rollers to align the belt. Both methods use different belt designs, so be aware.What kind of belt tracking does the conveyor have? Some bet conveyors have "Crowned rollers" that are a slightly larger diameter in the middle of the roller. On a centre drive conveyor the belt will not want to grip the powered roller and your belt could well remain stationary. This is used to align the belt.

What if you want a flighted belt? Not possible with a centre drive for this very reason. However you also have to look at the actual conveyor machine itself if you are going to get this right. Mainly they are used for horizontal transport of products, but now advancements in the machine and belts allow them to be used also for ascending and descending product applications.What are the diameters of all the rollers involved (And I mean all the rollers involved) on the machine? Not all rollers are visible; some can be hidden from view inside a centre drive module for example. If so, then the bearings may well need to be upgraded and some if not all parts be replaced with stainless steel or plastic components. The reason for this dimension and the reason why it's so important is that the more rigid the belt is, the less flexible it is and the less likely it is to wrap around a small roller.Selecting the right belt for your conveyor.

Conveyor belts have been utilised in a multitude of industries for many years.Will the belt get wet or be cleaned frequently? If you are changing the function of the conveyor to say a food environment, then the likeliness is that the conveyor will be frequently washed. Conveyor belts are used in industrial applications but also on large farms, in warehousing, from freight-handling, down to your local supermarket and in movement of bulk raw materials..Is the conveyor an end drive or a centre drive? Centre drives usually have pinch rollers and therefore the top and bottom surfaces of the belt will make contact with the rollers, unlike with an end drive. If this happens you will lose traction at the drive end and the belt will rise up at each end of the conveyor, not good
