The surface of the conveyor belt is made rough and tight so that the object placed on it does not slip when the belt moves or stops due to inertia. The rough surface increases friction and therefore helps to hold objects more firmly. Many of the first models of conveyor belts were made of leather because of its durability and accessibility. The leather is also shock resistant and has a good grip.
Drag is a less obvious source of wear and tear. Materials that adhere to the belt after the point of discharge can fall off the belt at any point. If left unaddressed, this drag can accumulate on the floor, under the conveyor, in confined spaces within the system, or in the components themselves. If this build-up grows large enough to reach the belt, it can constantly wear down the top cover through constant contact.
This damage will occur more quickly when materials have particles with sharp edges and higher levels of abrasion. This arrangement not only causes the material to become trapped and damage the belt, but it also reduces the cross-sectional area of the duct wall and, in turn, reduces the capacity of the conveyor. If the temperature of a material exceeds the specifications of a belt sufficiently, the holes may completely burn through the belt. SEMCOR has been distributing high-quality industrial products, including conveyor belts, since 1907. Although it has not been confirmed, many believe that the first conveyor belt appeared between the end of the 18th century and the beginning of the 19th century.
A similar type of wear can also occur on the belt if excess belt materials are used as a dust seal, since the highly abrasive housing will wear out the top cover more than a designed sealing system. Belt cleaners usually contribute to the wear and tear of the upper belt cover, but this damage is usually an acceptable compensation, since it helps prolong the life of the belt. This problem may be due to excessive tension on the belt or foreign materials entering the belt. When the cupping of the belt represents a curve along the width of the belt, an inclination refers to a curve along the belt.
Many different technologies have been developed to identify and correct belt misalignment, including self-adjusting pulleys and laser studies of conveyor systems, but the fundamental key is to identify the source of this error. After Charles Goodyear patented vulcanized rubber in 1844, conveyor belts experienced another significant change in production capacity. The strong impact of large or sharp materials can cause significant damage to the top cover of a conveyor belt. In addition, the twisted joints are relatively located around the slice itself, while a curvature can cross the entire section of the belt, causing constant problems along the conveyor.
Delamination is a condition in which the layers of the housing of a conveyor belt separate or the housing as a whole is separated from the top cover. These belts are part of many different types of conveyors, including inclined, horizontal, food-grade and aerial conveyors, but are not used on chain, pneumatic or screw conveyors. Not all industries have the need or budget to implement computerized conveyor belt technology in their already efficient production line. However, the design and composition of each belt determine what product, weight, speed and industry the belt is most suitable for.
