usher grinder raw materials for cement


How to Process Sand-gravel Aggregate? |

As the main raw material in concrete, aggregate plays the role of skeleton and support in buildings. When mixing materials, cement is mixed into a thin paste by water. If it is not added with aggregate, it will not be made and can not be used eventually. Therefore, aggregate is a very important raw material in construction.

Rawmill - Wikipedia

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
