Големи икономии чрез маршрутно-базиран мониторинг на състоянието на топкова мелница

Използвайки ръчния инструмент Leonova Emerald и акселерометрите DuoTech , норвежката минна компания Rana Gruber следи механичното състояние на критичната за производството в този случай топкова мелница. Планираната подмяна на повреден главен лагер, открит чрез маршрутно измерване, спести на компанията значителни суми.

Топковите мелници са приложение с ниска скорост (типичната скорост на въртене е 10-20 об./мин.), при което повреда на лагер може да бъде предизвикателство за откриване. Мониторингът на състоянието на топковата мелница започна през декември 2016г. и от самото начало показанията посочваха потенциална повреда на главния лагер на  изхода.

С течение на месеците показанията остават на доста високо, но стабилно ниво, докато стойностите на BPFO показват нарастваща тенденция и ясни BPFO съвпадения. Когато лагерът беше подменен по време на планирано спиране за поддръжка, повредите на външната гривна на лагера бяха потвърдени.
