mill power required to grinding media

Stirred Media Detritors (SMD) Outotec

The power drawn by the SMD motor is required to establish the grinding rate. As the grinding media wears fine enough to exit through the mill screens the total media charge will diminish and the power draw will decrease. Media should be added either manually or automatically to maintain as consistent a power draw as possible. SMD is normally
