一、问题的提出实验和生产实践证明，引起球磨机电耗变化的主要因素是球磨机充填率的大小，而充填率的变化，直接影响磨机功率的变化。对一定规格的磨机而言，功率仅与充填率有关。并不是要求磨机的功率越小越好。功率变小了，说明磨机的充填率小了，耗电量也就降低了，但充填 First, the question put forward Experiments and production practices have proved that the main factor that causes the ball mill power consumption changes is the size of the ball mill filling rate, while the filling rate changes directly affect the mill power changes. For a certain size of the mill, the power is only related to the filling rate. It is not a requirement that the mill’s power be as small as possible. Power becomes smaller, indicating that the mill filling rate is small, power consumption will be reduced, but the filling
