--- title: Metal-Tipped Primary Belt Cleaner Improves Removal of Abrasive Carryback description: Ensuring conveyor belt cleaners are correctly installed and maintained will improve carryback removal while decreasing spillage and cleanup. image: https://blog.martin-eng.com/hubfs/PrimaryCleaner.png --- [Skip to content](https://blog.martin-eng.com/problem-solved-papers/metal-tipped-primary-belt-cleaner-improves-removal-of-abrasive-carryback#main-content) [![Martin Engineering](https://blog.martin-eng.com/hubfs/Martin%20Engineering%20Logos/martin-sig_white.png "Martin Engineering")](https://www.martin-eng.com/) ## Problem Solved Paper call 800.544.2947 # Metal-Tipped Primary Belt Cleaner Improves Removal of Abrasive Carryback [Martin Engineering](https://blog.martin-eng.com/problem-solved-papers/author/martin-engineering) September 20 2024 [Safety](https://blog.martin-eng.com/problem-solved-papers/tag/safety) ### Problem ![PSPBlog_VitalisOlbia_Problem](https://blog.martin-eng.com/hs-fs/hubfs/PSPBlog_VitalisOlbia_Problem.jpg?width=350&height=193&name=PSPBlog_VitalisOlbia_Problem.jpg)The Vitali Olbia plant transports highly abrasive sand and gravel via conveyor belt to produce concrete and asphalt. Having recently launched the [Mr. Blade®](https://www.martin-eng.com/content/page/545/mr-blade-replacement-blade-installation) program in Italy, a Martin Engineering technician visited the site and noticed that the existing belt cleaners were allowing a substantial amount of carryback to remain on the 800-mm wide belts, creating significant [spillage](https://foundations.martin-eng.com/en/knowledge/material-spillage). As a result, two employees were assigned to clean up the fugitive material every day, taking time away from more productive activities. In addition to the wasted material and increased labor time, this also placed the workers in close proximity to the moving conveyors, introducing a possible safety risk. ### Solution ![PSPBlog_VitalisOlbia_Solution](https://blog.martin-eng.com/hs-fs/hubfs/PSPBlog_VitalisOlbia_Solution.jpg?width=350&height=262&name=PSPBlog_VitalisOlbia_Solution.jpg)After a thorough review of the conveying system, the Mr. Blade® technician recommended two [Martin® QC1+™ HD Belt Cleaners](https://www.martin-eng.com/content/product/15293/qc1plus-cleaner-hd) with metal-tipped blades to handle the highly abrasive materials. The belt cleaner consists of a primary blade with a spring tensioner system designed to keep a tight seal across the blade profile while minimally wearing on the belt or splice. For the first conveyor, a standard orange [blade](https://www.martin-eng.com/content/page/683/high-performance-urethane/) was used for its ability to handle abrasive conditions. For the second belt, which feeds the oven, a green high-temperature blade was installed due to its ability to withstand continuous temperatures of -40 to 150°C (-40 to 300°F) and intermittent exposure to temperatures as high as 177°C (350°F). ### Results ![PSPBlog_VitalisOlbia_Results](https://blog.martin-eng.com/hs-fs/hubfs/PSPBlog_VitalisOlbia_Results.jpg?width=350&height=262&name=PSPBlog_VitalisOlbia_Results.jpg)Upon completing the installations, the improvement was readily apparent, and the plant manager noted the absence of fugitive material that accumulated so quickly before. Instead of daily cleanup, maintenance workers now check for spillage and remove as needed just once every 6-7 weeks. "We subscribed to the Mr. Blade® program at a number of our production sites, and we quickly saw the benefits in reduced spillage and increased system uptime," said Luigi Pinna. "We anticipate that the program will continue to help us improve productivity, reduce carryback, and minimize spillage, and we hope to extend the program to more of our plants in the coming months."
