Approach to High Temperature of Cement Ball Mill

2021-6-6  Approach to High Temperature of Cement Ball Mill. In the operation of cement ball mill, the stop can cause a large temperature difference on the mill body, resulting in significant thermal stress and thermal deformation, and sometimes even cause mechanical damage of the ball mill, such as the geometric deformation of the liner.Starting the thermal deformation after the stop grinding can ...

Keeping Concrete Cool In the Heat of Summer Concrete ...

1993-6-1  In summer, the cement temperature can be high, so it may be necessary to store cement longer to let it cool. Aggregates can be cooled by spraying them with clean water and storing them in the shade. It can be even more effective to reduce the heat-generating capacity of the mix by reducing the cement. The hydration of portland cement generates ...
