The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
(1) the cement cooler can only cool the ground cement, which has no effect on reducing the internal temperature of cement mill, avoiding gypsum dehydration, preventing ball packing forging, increasing the output of cement mill, avoiding the excessive temperature of mill bearing and so on.
temperature increase of approximately 14 K after 30 min milling in an MM200 mixer mill [6, 11]. McKissic et al. observed a temperature of 50 C after 1 h milling in a Spex mixer mill and Takacs and McHenry reported milling ball temperatures of 66 C[12, 13]. Comparably higher tem-peratures can be reached in planetary ball mills (PBMs),
5、affected by the ambient temperature of the ball mill. The ambient temperature also affects the ball bearing temperature, such as season, location, and even the ventilation of workshop level, will affect the bearing temperature. 6、the main bearing cooling water temperature and the effect of cooling water

effect of slurry rheology and flow rate on mill behaviour. He had already highlighted the interaction between slurry and media in the mill by looking at the mill grinding efficiency. At that time, it was difficult to acquire a lot of valuable The performance of ball mills is very sensitive to the
Selection and design of mill liners This model has been added to a ball charge motion model allowing the simulation of mill wear rates as well as ball mill element wear and its affect on
Due to the impact of grinding minerals, mechanical friction energy of grinding materials and the energy released when the materials are broken, it is easy to make the temperature of the ball mill too high, plus summer high temperature weather, the working environment is even as high as 40 or 50 degrees.In this way, the ball mill in high temperature for a long time on the equipment as a whole

The influence of crucial reaction parameters on Knoevenagel condensation in planetary ball mills was investigated. Rotation frequency (νrot), milling ball diameter (dMB), milling ball filling degree (ΦMB), and beaker size had obvious influences on yield. It was found that higher νrot, lower dMB, milling beakers with larger diameter, and a ΦMB of ∼0.3 are advantageous for the reaction.
