Raw grinding Satarem.co
The raw material must leave the mill with an appropriate fineness to enter into the burning process. In the raw grinding process, the raw material cannot be homogenized due to the short retention period. Raw material grinding can be divided into: Dry grinding process: The desired size of the raw material depends on the burning process requirements and is normally in the

Rawmill
Wet grinding is more efficient than dry grinding because water coats the newly formed surfaces of broken particles and prevents re-agglomeration. The process of blending and homogenizing the rawmix is also much easier when it is in slurry form. The disadvantage is that the water in the resultant slurry has to be removed subsequently, and this usually requires a lot of energy. While ene
