Abstract: A method of operating a grinder includes acts of: starting a first grinding cycle of a given duration; feeding the grinder with a given amount of material to be ground and grinding the material by rotating a rotary grinding member of the grinder for a period of active grinding; idly rotating the rotary grinding member for a period of idle rotation following the period of active grinding, for removing residual ground material from the grinder; estimating when the given amount of material has been ground, based on an operating parameter of the grinder; and adapting the given duration for a subsequent grinding cycle based on an estimated duration of the period of active grinding of the first grinding cycle.

Abstract: The method of operating a grinder (1) comprises the steps of: starting a first grinding cycle of a given duration; feeding the grinder with a given amount of material to be ground and grinding said material by rotating the rotary grinding member (5) of the grinder for a period of active grinding; idly rotating the rotary grinding member (5) for a period of idle rotation following the period of active grinding, for removing residual ground material from the grinder; estimating when the given amount of material has been ground, based on an operating parameter of the grinder; adapting the given duration for a subsequent grinding cycle based on an estimated duration of the period of active grinding of the first grinding cycle.
