A crucial parameter that defines the performance of a mill is the energy consumption.The power supplied to the mill is used primarily to lift the load medium and charge.Additional power is required to keep the mill rotating.8.1.3 power drawn by ball, semi-autogenous and autogenous mills a simplified picture of the mill load is shown in figure.
The mass fraction is 45. -65. therefore, the lattice type ball mill is often used as a rough grinding device, or a grinding operation in which the material to be ground is liable to be muddy. the milled product has a relatively fine particle size, and the production efficiency is small.
Influential elements on the productivity of a ball mill 1. material type materials are different in hardness, humidity. lower the hardness of the material is, higher the productivity of a ball mill is. on the contrary, if the material is of high hardness, the ball mills productivity will be
Ms holderbank engineering, canada has developed a control strategy for ball mills which can maintain a mill production near optimum, with little operator intervention. the main principle of the concept is that maximum production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific
