The ball mill is a large-energy-consuming device in the mineral equipment, but it is also an indispensable main equipment in the mine. The main user of the ball mill is broken. So where is the energy consumption of the ball mill? This is a lot of people want I know, now let's make a simple analysis
The electric energy consumption of the input motor during the mill is three aspects
1. The loss of the electric motor itself, accounting for accounting The total power energy is related to the efficiency of the motor itself.
2. Mechanical friction loss, that is, the friction between the sheets causes the rotation of the cylinder to rotate the power consumed, and the friction loss measured by the test is very inconsistent. The structure, transmission method, and lubrication of the mouse and bearing, and is proportional to the speed ratio, approximately 10-15% or so
3. Useful power to move abrasive medium motion Therefore, the power consumed by the grinding effect, the weight of the size of the grinding medium and the rotational speed of the mill, about 75% of the electric energy
Since the useful power is used to move the grinding medium, so according to Medium movement to establish theory of useful power, is an inevitable method. There are many ways to calculate this, and it has always been argued and supplemented. The general formula for the status and throttle state useful power to understand the methods and some important situations of analysis problems, as the basis for further studying the power consumption of abrasive machines.
