  The particle size of the key high chromium ball gradation grinding material for high efficiency production of cement ball mill should be reduced as much as possible (depending on the crusher capacity), and the moisture content of the grinding material should be reduced as much as possible.

The particle size of the material should be relatively stable, the high chromium ball gradation of the cement ball mill should be relatively stable, and the average ball diameter should be reduced as much as possible in order to increase the specific surface area and improve the quality of the cement ball mill. In winter and spring, the moisture content in the air of grinding materials is different. Generally speaking, the moisture content of grinding materials is heavy in spring, the average ball diameter of gradation is larger, and the dry moisture of air in winter is 1% lower. Some, the average ball diameter of the required grading is smaller.


  The improvement of the feeding system of the ball mill is to improve the working efficiency. In order to meet the needs of the users better, a large number of experts are organized to carry out the transformation of the feeding system of the ball mill, so as to meet the requirements of the user, and the general transformation process is as follows:

  In the design, transformation and production of the ball mill widely used in the mine, a wealth of experience has been accumulated.

In addition to the formation of its own unique ball mill series, the energy saving transformation of the old ball mill has also been carried out. in this paper, the relevant situation is introduced as follows. Improvement of feeder in the past, the ball mill mostly used spoon head combined feeder to feed, because the spoon head was thick and heavy and eccentric, as well as the friction and impact with sedimentary ore during sand excavation, the ball mill produced periodic eccentric load and impact load. When the motor runs under variable load, not only the capacity increases and the current fluctuates greatly, but also shows the variable speed motion of half cycle acceleration and half cycle deceleration. The periodic eccentric load and the impact load have great influence on the wear of the main bearing, the force of the connecting bolt of the cylinder body, the meshing of the size gear and the heating of the motor, and the service life is shortened.
