finish grinding mill cement storage shipping limestone clay Cement is made from limestone, clay, sand and gypsum in a continuous drying and grinding process. The limestone is pre-crushed, mixed with sand and clay and dried in a raw mill. The raw mixture then is conveyed to the rotary kiln, where it is burnt to cement clinker at 1.450 °C.

Concrete Finishing - Levels of Stone Exposure
It's where we grind the top 1-3mm off the surface, usually going over the entire floor just once. There is often no stone exposure in some areas, while other areas have a little or a lot depending on how the slab was poured. This type of concrete finishing is often used for the industrial look, or for garages, restaurants, outdoor areas etc.
