Main motor is one of the main auxiliary parts of ball mil.  If the choice of the main motor is not appropriate, it often creates some wrong conditions when ball mill is running up. In order to avoid the main motor is not suitable and delays the time for the ball mill normal being put into use, we choose set up some principles for ball mill:

In the selection of ball mill main motor, in addition to generally consider the motor characteristics, you also should take other issues of principle into account:

1.    The initial investment of ball mill main motor and the operation cost of ball mill must be balanced.

2.    You must consider other equipment motor type of the concentrator, and it is also the basis of the power factor of power network.

3.    When determining the rated voltage of motor ball mill, should consider variable pressure situation of area power grid as well as the capacity of the grid size.

4.    Make sure that the motor should be applied forunified evaluation with the mechanical transmission of ball mill. For assessment, we should take the mechanical mill reducer manufacturing conditions into account.
