In the production of ball mills, due to the energy conversion and the temperature of the materials entering the mill, the temperature in the ball mill will also increase after a period of time.

The main reasons are as follows:

1. From the analysis of mechanical equipment, because the cement ball mill is in operation, especially when the grinding is stopped, it causes a large temperature difference on the grinding body, which causes significant thermal stress and thermal deformation, and sometimes even causes damage to the cement ball mill's parts, such as linings. Geometric deformation of the liner, etc. Thermal deformation causes a certain coherent force when it is restarted, which forms the current pulsation and its own vibration during operation. In addition, the heat of the cement ball mill is transmitted to the main bearing, which increases the temperature of the main bearing and makes maintenance difficult.

2. From the process analysis, the abrasiveness of materials decreases with the increase of temperature. In the finer areas of the ball mill, the fine particles of the cement will rub against each other and cause electrostatic adsorption. In addition to agglomeration, they also adsorb on the grinding body of the cement ball mill, forming a so-called buffer layer, which significantly reduces the grinding effect of the cement ball mill. ; And the higher the temperature, the more serious the side effects of this agglomeration. In addition, the high temperature inside the cement ball mill can cause false or rapid setting of the cement, which affects the quality of the cement.

The higher the fineness, the more obvious the effect of temperature.
