Abstract

Изобретение касается способа определения степени заполнения мельницы и углового положения (φ) нижнего края загруженного в нее материала, при этом колебания, действующие на электродвигатель мельницы, используются для определения положения нижнего края загруженного в мельницу материала, состоящего из измельчаемой массы. Согласно изобретению из полученных результатов измерений (P(n)) потребляемой мощности или вращающего момента с использованием анализа в частотной области определяют фазу (θ) указанных колебаний мельницы и посредством фазы колебаний (θ) определяют угловое положение (φ) нижнего края загруженного материала.Международная заявка была опубликована вместе с отчетом о международном поиске.
