Neponset, Illinois – The new Mr Blade replacement programme for belt cleaners from Martin Engineering will deliver fresh polyurethane blades direct to factories. The blades are specified and custom-fitted on site, and will be installed free of charge.
“Although many conveyor users probably don’t realise it, product freshness is a significant issue for urethane belt cleaners,” said Chris Schmelzer, director of the company’s wear components business group. “Because urethane is a hygroscopic material, it tends to absorb moisture from the ambient air over time, which causes a degradation of physical properties. The process gradually decreases the cleaning performance, and shortens wear life.” The usable period is about two years, after which the blade’s physical properties are likely to be affected, he added.
