Flat Belt Conveyor With Roller for Bag Transfer Application Flat Belt Conveyor With Roller for Bag Transfer Application, the traditional industrial workhorse, belt conveyors complement the powered roller conveyor. Whereas a roller conveyor can only handle larger items with a flat lower surface and a low center of gravity, the belt conveyor can accommodate almost anything: from discrete packages to small components; powders to aggregates. Items that might be prone to toppling are less likely to do so on a belt conveyor than they are on a powered roller conveyor. They can also handle semi-solid or sticky items such as clay or bread dough etc. The belt conveyor is very flexible, able to form bends, as well as gradients. It also permits a very wide range of belt material and geometry, including such things as antibacterial belts for the food industry, contoured and/or flighted belts for aggregate handling, wire mesh belts (to allow air or liquid to circulate around a product), and a wealth of other applications. The limitation of a conventional belt conveyor is – ultimately – the carrying weight. Beyond a certain weight threshold, the belt will begin to slip. At this point you might need to consider a chain-driven belt conveyor, or possibly a plate link conveyor. The latter is also the conveyor of choice for sharp or abrasive products that might puncture or tear a conventional conveyor belt.
