Medium Voltage VSDs in mill drive applications

Frozen charge is a common occurrence with mill applications and it is therefore an advantage that the VSD can offer protection against this condition. Frozen charge can occur when the mill has been stopped long enough for the product to solidify. If the mill is started again this solidified product may fall and damage the mill lining.

Model Amelunxen SGISAGMILLING

Amelunxen SGI Model. This is a model that estimates the specific energy consumption of a SAG or AG mill plus ball mill circuit using the equation by Amelunxen (2014) for E SAG and the classical Bond work index equation for E ball substituting CF ball in the place of the Rowland efficiency factors.. The model requires manual calibration factors for both equations (CF SAG and CF ball
