ball mill temperature rise nigeria

The ball mill in operation, the grinding material accounted for only a small part of the total energy consumption, while most of the energy is converted into heat energy and, therefore, get a lot of material in the heat discharging through the hollow shaft or slip ring, heat is transferred to the Bush, will make the main bearing liner temperature increased significantly, up to the bush temperature 70~80 degrees …
