Abstract

The invention concerns a procedure and an arrangement for measuring the volumetric efficiency of a mill, whereby the variations in the power to the mill's electric motor 8 are utilised for the measurement. For measuring the volumetric efficiency in accordance with the invention, use is made of suitable constant-frequency oscillations which are caused by the lift beams 4 of the mill's housing and which affect the electric motor 8. In order to synchronise the measurements, a measurement transmitter 3 has been set up outside the mill's 1 perimeter, and on the mill's 1 perimeter there is a matching piece of equipment 2 corresponding to the transmitter. In addition, the measurement transmitter 3 and the power transmitter 9 of the mill's electric motors have been suitably connected to a measurement processor 5. <IMAGE>
