M istracking is prevented by first understanding the basic patterns of belt behaviour and then following established procedures to carefully align the structure and components to correct fluctuations in the belt’s path. Mistracking indicators: becoming a fire hazard. When a high-speed belt edge contacts the stringer, it can cause fraying, shredding, or splice damage and cut through steel mounts. rise. Spillage fouls idlers and pulleys, causing them to seize, leading to friction damage on the belt and potentially FEELING CENTERED: THE ZEN OF CONVEYOR BELT TRACKING The moment a conveyor belt wanders, material spills, system safety and productivity quickly degrade, and operating costs
• Belt edge damage • Excessive spillage • Idler/Pulley fouling • Off-centre belt at head or tail pulley
Sensing slight variations in the belt path helps make immediate micro-adjustments.
Common causes of mistracking There are three general groups of common causes for mistracking. Belt and Splice: If the belt is poorly manufactured or stored improperly, it can bow or camber. Poor installation of a vulcanized or mechanical splice can result in a splice that causes belt tracking problems. Exposure to weather or to chemicals can degrade the carcass (plies or cords) and the cover of the belt, leading to bowing, cambering or
A Martin expert draws out a quick sketch to help an attendee visualise the solution.
By reducing the energy required to correct the belt, wear on both the conveyor and tracking equipment is reduced, resulting in a longer, more efficient service life.
