The steel ball has a close relationship with the size of the main motor current.Experienced milling workers are at the time of operation of the ball mill, and the changes in the main current of the ball mill are always observed.
In the case where the ball mill does not change, and the working conditions are good, the higher the current, the more the ball mill is large; but the more less.
The authors are observed by long-term trials of φ3600 × 4000 wet lattice ball mills, and the voltage of the synchronous motor supporting the ball mill is 6000 volts, the AC frequency is 50 Hz, the power is 1100KW, the rated current is 125A.When the motor is idling, the current is 0; the motor drives the ball mill empty load time current is 25A; when the ball mill is 60t / h, the synchronous motor current is 85A; when the ball mill is constant, the steel ballWhen adding 5T, the current increases 4A; when the amount of mine is increased by 5T / h, the steel ball is not changed, and the current increases 5A.
