How Can Get the Optimal Running Speed of Ball Mill?

In the running process of ball mills, the running speed is a crucial working parameter as suitable running ratio can improve the working efficiency of the ball grinding mill. Too low running speed will influence the working capacity of the milling equipment, too high running speed might aggravate the abrasion of the spare parts and lower the working efficiency of the grinding mills. For this reason, it is necessary to seek for the optimal running speed of ball mills.

The method of determining the optimal running speed of ball mill is, in the falling process of the steel balls, the kinetic energy at the falling point can play the role of crushing, and the radial kinetic energy is mainly used for crushing the materials, and the running speed gained with the maximum accumulated value of every layer of radial kinetic energy factors as the goal is the optimal running speed of ball mill.

The kinetic energy and kinetic energy factor of the steel balls in the falling movement are analyzed in the following: The total kinetic energy of the falling point of the steel balls can be divided into radial kinetic energy and tangential kinetic energy. The former mainly crushes the ores and the latter main grinds the ores in the relative movement.

The crushing effect of the milling equipment is determined by the kinetic energy at the falling point of the steel balls in the parabolic movement. For this reason, the accumulated value of every layer of radial kinetic energy factors should be the basis of measuring the running speed of the ball making machine.
