Enhancing Conveyor Belt Efficiency with Raised Elements
Raised elements on a belt surface, such as cleats, ribs, chevrons, and lugs, are often used to assist in the transport of materials. These features allow a conveyor belt to carry material at steeper angles than would be possible with a flat belt. This is particularly beneficial for moving lumps or stones that could easily roll down an unobstructed incline.
Cleats or ribs act like walls or shelves installed perpendicular to the belt edges. Chevrons are arranged in a V-shape, while lugs are individual "islands" or pillars on the belt’s surface. These elements come in various patterns and styles, with heights determined by the specific application. They can be molded directly into the belt during its manufacture, or they can be bolted or vulcanized to the belt surface later.
It's important to note that taller cleats, ribs, chevrons, or lugs are more prone to damage and can make the belt harder to clean and seal.
To improve traction between the belt and the conveyed material, a top cover with inverted chevrons can be used. Unlike standard chevrons, inverted chevrons are recessed into the top cover, similar to tire treads. These grooves are cut into the belt cover with a router and can be angled like chevrons or straight across the belt at 90 degrees to the edge. This design enhances the cleaning and sealing of the belt with traditional systems, although there is a risk of material filling the recessed cleats.
