How to determine how much the charcoal ball mill is loaded?

　　How much 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.

　　By observing the long-term test of φ3600 × 4000 wet plaid grinding machine, the voltage is 6000 volts with a synchronous motor supporting the ball mill, and the AC frequency is 50 Hz. The power is 1100 kW, the rated current is 125A. The current is 0 when the motor is idling; the motor is driven when the ball mill is operated at the time of operation of 25A; when the ball grinding the mine is 60t / h, the synchronous motor is 85A; when the ball mill is constant, the steel ball When 5T is added, the current increases 4A; when the amount of mine increases 5T / h, the steel ball is not changed, the current increases 5A.
