Where is the main consumption of the energy consumption of the gold ore ball mill?

　　The ball mill is a larger equipment that can be energy consuming in the mineral equipment, but it is also an indispensable main equipment in the mine. The main user of the ball mill is broken, then 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. Loss of the electric motor itself About 10% of the total electric energy, related to the efficiency of the motor itself.

　　2. Mechanical friction loss, that is, the friction between the module makes the power consumed by the rotation of the cylinder. The friction loss measured by test, It is very inconsistent, the structure, transmission method, and lubrication of the mouse journal and the bearing, and the propagation is proportional to the speed of 10-15%

　　3. Useful power, used to make the grind Mining medium motion generates the power consumed by the grinding effect, the weight of the size of the grinding medium, the rotational speed of the mill, about 75% of the electric energySince the useful power is used to move the mill Therefore, based on the motion of the medium, it is an inevitable method. There is a certain method. There are many calculation formulas in this regard, and it has always been argued and supplemented. As for the practicality of contamination, it is inconsistent, it is difficult to conclusion, below Introduction to the general formulas for calculating the status of the diarrhea and the throttle state, in order to understand the methods and some important situations of analysis problems, as the basis for further studying the power consumption problem of abrasive machines.
