Processed alumina powder exits the refinery on conveyor 721, which is ~450 meters in length, traveling at 2 meters per second. The belt was experiencing serious tracking issues, which caused [damage to the belt](https://foundations.martin-eng.com/en/knowledge/belt-conveyor-and-component-damage) and structural components, as well as [spillage](https://foundations.martin-eng.com/en/knowledge/material-spillage) along the conveyor path. Operators had been using self-aligning idlers from a local manufacturer, but were unable to effectively control the [belt wander](https://foundations.martin-eng.com/en/knowledge/causes-of-conveyor-belt-mistracking). The company needed to correct the issue to avoid further damage and minimize fugitive material. ### Solution ![martin-tracker](https://blog.martin-eng.com/hs-fs/hubfs/Foundations/Foundations%20Microsite%20-%20(Brafton%20articles)/martin-tracker.jpg?width=420&height=220&name=martin-tracker.jpg)Martin Engineering technicians performed an audit on the conveyor and recommended four [Martin® Trackers™](https://www.martin-eng.com/content/product/171/tracker) on the carrying side and five on the return side to stabilize the lengthy run. Rollers attached to the end of a sensing arm assembly ride both sides of the belt edge, detecting even slight variations in the belt path. Employing the force of the wandering belt, the arms automatically position a steering idler in the opposite direction of the misalignment. Transferring the motion to the steering idler through a unique parallel linkage requires less force to initiate the correction, so fine-tuning of the path can be continuous, active, and precise. ### Results Utilizing a troughed [idler support system](https://www.martin-eng.com/content/product_subcategory/475/conveyor-belt-support-products) on the carrying side of the conveyor to retain the proper angle and keep the load centered, the belt tracker upper unit employs guide rolls that are mounted just one-quarter inch (6 mm) from the belt for high precision when making opposing adjustments to the idlers. Belt tracker lower units are hung from the mainframe under the return belt every 70 to 150 feet (21 to 50 m) and use a single flat rubber idler to bring the belt back into alignment. The customer reports that the belt is now properly centered, and the results have been so positive that the company is planning to install additional Martin® Trackers™ on its other conveyors.
