Intergrinding (co-grinding) in classical ball mills (closed system) leads to a broad PSD, which is usually regarded as beneficial, e.g. regarding workability. Nevertheless, above a certain limit the fine limestone has an excessive water adsorbtion and separate grinding (ball mill and mixing equipment) is favoured. 4
each ball position with a bright finish and sharp demarcation, often surrounded by a ring of brown dehris-indicates excessive external vibration. A small relative motion between balls and raceway occurs in non-rotating ball bearings that are subject to external vibration. When the bearing isn't turning, an oil film cannot be formed to prevent
